  • Why won't my Nokia E52 charge on some USB ports

    - by snot
    I have two computers. If I connect my Nokia to one of them using the usb cable the charge process will start. If I connect the phone to the other computer (using the same cable!) it won't start charging. Any suggestions what the problem is? (I couldn't find a usb related difference between both computers)

  • HOSTS ignored when disconnected [closed]

    - by Synetech
    Problem I’m seeing a strange and extremely frustrating problem. Any system that is not connect to the Internet (Windows 7 shows the no Internet access icon because it cannot constantly ping Microsoft’s servers) cannot even access locally hosted servers. Hypothesis The problem appears to be that the HOSTS file is not being used to resolve DNS entries when there are no active NICs. Tests / Reproduction You can reproduce it as so: Disconnect a system from the Internet (make sure all wired and wireless connections are disconnected). If necessary, add an entry to the HOSTS file (e.g., 127.0.0.1 foobar or 127.0.0.1 foobar.com) Open a command-prompt Type ping foobar or ping foobar.com Observations The screenshots below show a clear and demonstrative example. In the first snap, a laptop is connected to a router wirelessly. The HOSTS file has only three entries and they resolve just fine. In the second snap, the wireless radio is turned off, so the entries in the HOSTS file are ignored. Moreover, notice that pinging localhost still works even without any active NICs (as does 127.0.0.1), but it is using the IPv6 address (must be hard-coded). You can see the same results in Windows XP with no IPv6 installed, so it has nothing to do with IPv6. I tried pining what should have resolved to 127.0.0.1 while the desktop system (with no wireless NICs) was connected via its Ethernet adapter, then again after pulling the cable from the router and waiting a couple of seconds, then again after plugging the cable back in. The same thing happens if instead of pulling out the cable, the NIC is disabled through software (the [Disable] button in the NIC’s Status dialog or via Device Manager). Conclusions It looks as though the HOSTS file is only being read and used if there is an active NIC, otherwise it is being ignored. This makes some sense in that if there are no active network adapters, then presumably there will not be any network activity, and thus no need to resolve host names via the HOSTS file. This assumption is specious however because it precludes locally hosted virtual servers. The HOSTS file should be used regardless of external DNS server connectivity, otherwise you cannot use simple/consistent/testing-production names for locally hosted servers when not connected to the Internet (for example web servers; help servers for Visual Studio, 3dsmax, etc.; and so on). Question Does anyone know how to force Windows to use the HOSTS file even if there are no active NICs? Appendix Figure 1: While the wireless NIC is connected to the router (the cable-modem is in standby, so no external Internet connectivity). Figure 2: With the wireless radio turned off (the Ethernet port is not unconnected in both cases). Figure 3: Same results in XP with no IPv6

  • Looking for a fiber optic "switch" or "router" for home use

    - by Shrout1
    The gist of my question: What is a "fiber optic" switch called? I.E. a layer 2 ethernet switch that uses fiber TX and RX connections and sends layer 2 network traffic between the fiber strands that are connected. Can someone purchase a dedicated fiber switch that does not have copper ethernet ports? What is the current average price of a device like this? Not necessarily looking for product endorsements, just information Might not make sense to go this route if it is too cost prohibitive What type of fiber connector is used for terminating a fiber strand into a jack on the wall? Can fiber be "patched" using two jacks and a "patch" cable? Is signal loss a concern with the longest runs at 100-200ft, a patch cable and media converters? The full story: My parents had unterminated fiber optic cable and terminated Cat5e run throughout their home when it was built in 2004. 10 years later the Cat5e isn't providing the throughput that my father needs to accomplish multiple streams of HD and fast system backups throughout the house. He can't reach gigabit speeds across the distance of the Cat5e runs. We are both interested in terminating the fiber connections and using them as high speed "backbones" to copper switches in each room of the house. It would be easy to attain gigabit speeds (or better, eventually) using the fiber. I have searched and searched for a "fiber optic switch" or "fiber optic router" and cannot find the correct term to describe this piece of hardware. We can use fiber media converters at the end points of each connection, however it would be nice to have a "patch panel" set up in the network closet in the basement that has fiber connections on it and switches the ethernet streams between the connections/systems in the house. Each fiber media converter costs between $50-$100 a piece... After 10 or so terminated connections it might make sense to find a piece of hardware that does not require media converters. That would depend upon the cost of this hardware Somewhat unrelated, if we are able to route between these fiber strands successfully, what is the physical connector type used in a jack on the wall? Just like RJ45 has a wall outlet (depicted below): What is the fiber optic equivalent of this? In the interim could we "patch" a couple fiber strands together in the network closet? Would signal loss be of concern with a run length of 100-200 feet, a patch cable and two media converters? If that would work then it could be used until the funds are available for more.

  • apcupsd on Linux does not report on APC BackUPS Pro 900

    - by lserni
    From what documentation I could find, the UPS should be (is!) supported by Linux and ought to work with apcupsd. I looked for specific problems such as the infamous Microlink protocol, and found none. I have found a feedback from a guy in UK that reports using this very model on a not-too-different OS version (his OpenSuSE 12.1, mine 12.3 x86_64).

If I disconnect the USB cable, I get an apcupsd message to the effect that communications have been lost; and I get the "communication restored" broadcast too, if I reconnect the cable. apcupsd is monitoring. So everything tells me that it should work -- only it doesn't. Does anyone spot what I'm missing?

  • When a server gets rooted, should I disconnect network or power?

    - by Aleksandr Levchuk
    When a server gets rooted (e.g. a situation like this), one of the first things that should be done is containment. Quoting from Robert Moir's Answer: "disconnect the victim from its muggers" A server can be contained by pulling the network cable or the power cable. Taking into consideration the need for: Protecting victims from further damage Executing successful forensics (Possibly) Protecting valuable data on the server Which method is better?

  • Starting over and new to Ubuntu

    - by 2funnyyone
    We have been having repeated problems with our interent service and using windows xp & sp3 (users and premissions) I see no need for them. I started with computers long before windows. Every since sp 3 come out in 2009 I have had nothing but problems. I have lost so many computers to virius and trojans, we just stack them up. We are with Qwest/ Century link which is using advertising servers which I think is causing the problem. All the computers are networked together which is not how I set them up. I beleive Century link is networking them through assignment of a domain for our home. This causes all the computers to crash twice. This is getting expensive. We tried buying new harddrives but reinfect with hours of connecting to internet. I also beleive the modem, router and all computers are infected. I put combofix on this one and that is the only reason we are still online with this laptop. I am afraid to install new equipment because my partner and I are on SSDI and this cost a lot. I go to school at UOP and had to run off a flash and reboot this laptop to recovery every other day or so, this pass month. New plan is: We are getting ready to install new equipment but afraid to reinfect again. Need help to install new equipment. The plan is to use current internet services from Qwest/ now Century Link. The list of New equipment in order: Century link wireless modem is ZyXEL PK5000Z with 4 direct connect Ethernet ports Next Dell Optiplex 210L ( used auction purchase ) 2 gb ram 80 g hard drive Ubuntu 11.10 operating system Next Wireless D-Link router WBR-1310 with 4 direct connect Ethernet ports OK-------- Purchased Dell OEM disk for Repair or Reinstalling Windows XP Professional Operating system (2 roommates as well) All infected computers are Dell desktops or laptops with XP Pro Also purchasing Ubuntu 12.04 for 3 computers. We like the way it runs but still learning it. Questions 1] How do we fdisk the infected computers without infecting new system. We have Dos disks, but none have floppy dish drive. We do have a new floppy disk drive and usb adapter we purchased from Amazon. 2] We are thinking Avast internet security because of the boot scan. We want all software loaded before reconnecting. We can manually load our internet provider information. We purchased StopZilla $100 for 5 computers, but not sure that is what we need. But need how to setup ports security and services we will need. Really lost at this part. So we are safe when we go back on the internet. 3] Want to connect reloaded fdisk systems to router as public connection and no sharing. Do not want to network all computers. 4] Want parental/ ownership control from Ubuntu system for internet connection (Children and friends). Do we restrict at the modem and/ or router? Any help would be a blessing. I do not want to go alone on this anymore.

  • Creating a network link between 2 very close buildings

    - by Daniel Johnson
    I have a charity who have two adjacent medium sized modern detached houses (in the UK): the buildings stand next to each other and are less than 5 metres apart. They have DSL connected to a single computer in one of the buildings. They want to add a network with wireless, and want it to work across both buildings. Being a charity they need to keep costs down. The network would be used for sharing Word documents, e-mail, browsing and skyping. My initial thoughts were to connect the buildings with fibre. So: Option 1 Use fibre between the buildings. Sufficient cable and two TP-LINK MC100CM Fast Ethernet Media Converters. Cost ~£80.00. But there is the extra cost and hassle of running the cable down and up the external walls, lifting and relaying paving, and burying underground. Never having fitted fibre I'm also a little worried about going up the wall and then bending the cable at 90 degrees to go through the wall and into the building. Option 2 Use two TP-Link TL-WA7510N High Powered Outdoor 5Ghz 15dBi Wireless antennas to connect the buildings. There is a clear line of sight at first floor level. Cost ~£100. And much easier to fit than fibre! Is using the TL-WA7510Ns overkill? Is there something more suitable? I had hoped to use some Netgear stuff, e.g. two DGN2200, one in each house and also use them to provide the wireless link between the buildings. However, in bridge mode wireless client association is not available and repeater mode with client association only supports WEP security which isn't strong enough. Is there something similar that would be up to the job? Option 3 Connect the buildings with UTP cable. My concerns here are risk of electric shock due to a difference of potential between the buildings (or are they so close this shouldn't be an issue) and protection from lightning strikes. Is fitting lighting arrestors expensive? And what can be done to ameliorate against the risk of shock? This all falls outside my area of expertise so I would really appreciate some advice.

  • Computer doesn't boot with Entertainmen Keyboard 8000?

    - by Smetad Anarkist
    I have a Microsoft Wireless Entertainment Keyboard 8000, and when the charger/usb-hub is connected, the computer won't start. All I get is the bios boot screen, and it won't go further. But if I disconnect either the usb-cable or the power-cable to the charger the computer boots normally. Any suggestions as to what's causing this behaviour? I've tried the charger on two different computers with the same result.

  • MacBook (13 in. Aluminum late 08) power adapter starting to fail

    - by Mr. Man
    I have a MacBook (Late '08 13 In. Aluminum) with the Apple provided power adapter. I think it may be failing because It takes a little moving around with the cable nearest where it connects to the MacBook to get it to charge (small light turns on). The area of cable nearest the MacBook gets very hot, almost burning. Any ideas of how I could fix it? Hopefully without replacing the adapter. Thanks in advance!

  • Simple hardware RNG

    - by roygbiv
    I made a tongue-in-cheek comment to this question about making a hardware RNG. Does anyone know of any simple plans or can anyone descibe a simple hardware based RNG and the software to drive it? Go to Radio Shack. Buy a diode, an NTR resistor, a capacitor and serial cable. Cut off the end of the serial cable that does not fit on your computer. Solder the diode and resistor in series between pins DTR and DSR of the cable. Solder the capacitor between DSR and TXD pins. Write a small C program to do the following: Set DTR to 1. Start Timer. Monitor DSR until it goes to 1. Stop Timer. Calculate resistance from elapsed time. Retreive serveral bits from that value to use as part of random number. Repeat until enough bits have accumulated.

  • Does all the network card use the same frequency to send signals to wire?

    - by smwikipedia
    Hi, I am comparing my cable TV wire to my network wire. In a TV cable wire, different frequencies are used by different TV channels. And since a certain channel use a fixed frequency, I think the only left way to represent different signal is with the carrier wave's amplitude. But what about the network wire? For all the network card with the same type, do they also use different frequencies to send signals just like TV cable? I vaguely remember that they use frequency adjustment to represent signals. So the frequency should not be a fixed one. So how did all the network cards that sharing the same medium differentiate their own signal from others?

  • To File Share or to not File Share, that is the Question.

    To file share or to not file share, that is the question. The concept of the internet was developed in the 1960’s as a revolutionary idea to share information and data amongst a group of computers. The original concept was to allow universities and the United States Military share data for research and field operations. This network of computers was designed to provide redundant data storage and communications in case one or more locations were destroyed. Since the inception of the internet, people have attempted to use it for sharing data. As the Internet has evolved so did the users and the information they wanted to share. In today’s modern internet people can share information through various avenues, for example: websites, social networks, email, documents, executable files, data files and much more.  Unfortunately, as the internet and its users have grown, some industries have not paid attention. Currently, there are several industries that have really fallen behind in keeping up with current trends, and are severely paying the price for their lack of action. A current example of this is with the Recording Industry Association of America (RIAA) and file sharing. RIAA contends that customers who purchase music can only listen to the music and cannot share it with others. This can be seen when the RIAA sued Napster for distributing copyrighted music through a technology called file sharing. File sharing as defined by the Media Awareness Network is downloadable software that permits users to share music, video, image or book files directly with peers. Users of file sharing networks simply had to extract the music from a CD into a music compatible format. Typically most music files at that time where saved as MPEG file format. Once the users got music in this format it was very easy share their music with others. The big question now is who actually owns the music, does the music industry still retain the rights of the music regarding who has access to listen to it, or is it up to the owner of the music CD.  According to the First – Sale Doctrine, it is the right of the purchaser of the CD to decide who can access the information on the CD. In addition, the original owner looses all rights to the music once it has been sold.  The importance of defining who actually owns the music has a great impact on the future of the industry. If the industry is determined to be the actual owner of the music then anyone who has shared at least 1 fine with another is guilty of violating the copyright. However, if the owners of the CD are determined to be the owners of the music then the music industry will have to figure out some other way to protect their music so that it is more lucrative for them or they will go out of business.

  • IPv6, isn't it just a few extra bits?

    - by rclewis
    It's always an interesting task, to try and explain what you do to family and friends. I have described IPv6 as the "Next Generation Internet"  or "Second Internet" but the hollow expressions on my kids faces scream for the instant relief of the latest video game.  Never one to give up easily, I have formulated a new example - the Post Office... Similar to the Post Office the Internet delivers mail and packages based on addresses. As the number of residences, businesses, and delivery locations increased, the 5 digit ZIP Code (Washington, DC 20005) was expanded to ZIP+4  allowing for more precise delivery points (Postmaster General, Washington, DC 20260-3100). Ah, if only computers were as simple.  IPv6 isn't an add-on or expansion of the existing IPv4 Addressing, it is a new addressing model which will allow the internet to grow from a single computer in the basement of a university or your parents kitchen table, to support the multitude of smart phones, smart TV's, tablets, dvr's, and disk players, all clambering to connect for information. Unfortunetly there are only a finite number of IPv4 public addresses left, and those are being consumed at an ever increasing rate. Few people could have predicted the explosive growth of the internet or the shortage of IPv4 addresses we now face - but there is a "Plan B" and that is the vastly larger address space of IPv6.  Many in the industry have labeled this a "business continuity" problem,  when in fact most companies will be able to continue conducting business once they run out of existing IPv4 Addresses. The problem is really a Customer Continuity problem, how will businesses communicate with existing customers and reach new customers online who's only option is to adopt IPv6 when IPv4 is depleted? Perhaps a first step is publishing a blog that is also accessible via IPv6, it's just a few extra bits.

    - by Tijo Joy
    My intention is to create a .bat file that toggles the check box of "use automatic Configuration Script" in Internet Settings. The following is my script @echo OFF setlocal ENABLEEXTENSIONS set KEY_NAME="HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings" set VALUE_NAME=AutoConfigURL FOR /F "usebackq skip=1 tokens=1-3" %%A IN (`REG QUERY %KEY_NAME% /v %VALUE_NAME% 2^>nul`) DO ( set ValueName=%%A set ValueType=%%B set ValueValue=%%C ) @echo Value Name = %ValueName% @echo Value Type = %ValueType% @echo Value Value = %ValueValue% IF NOT %ValueValue%==yyyy ( reg add "HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings" /v AutoConfigURL /t REG_SZ /d "yyyy" /f echo Proxy Enabled ) else ( echo Hai reg add "HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings" /v AutoConfigURL /t REG_SZ /d "" /f echo Proxy Disabled ) The output i'm getting for the Proxy Enabled part is Value Name = AutoConfigURL Value Type = REG_SZ **Value Value =yyyy** Hai The operation completed successfully. Proxy Disabled But the Proxy Enable part isn't working fine the output i get is : Value Name = AutoConfigURL Value Type = REG_SZ **Value Value =** ( was unexpected at this time.

  • smtp.gmail.com from bash gives "Error in certificate: Peer's certificate issuer is not recognized."

    - by ndasusers
    I needed my script to email admin if there is a problem, and the company only uses Gmail. Following a few posts instructions I was able to set up mailx using a .mailrc file. there was first the error of nss-config-dir I solved that by copying some .db files from a firefox directory. to ./certs and aiming to it in mailrc. A mail was sent. However, the error above came up. By some miracle, there was a Google certificate in the .db. It showed up with this command: ~]$ certutil -L -d certs Certificate Nickname Trust Attributes SSL,S/MIME,JAR/XPI GeoTrust SSL CA ,, VeriSign Class 3 Secure Server CA - G3 ,, Microsoft Internet Authority ,, VeriSign Class 3 Extended Validation SSL CA ,, Akamai Subordinate CA 3 ,, MSIT Machine Auth CA 2 ,, Google Internet Authority ,, Most likely, it can be ignored, because the mail worked anyway. Finally, after pulling some hair and many googles, I found out how to rid myself of the annoyance. First, export the existing certificate to a ASSCII file: ~]$ certutil -L -n 'Google Internet Authority' -d certs -a > google.cert.asc Now re-import that file, and mark it as a trusted for SSL certificates, ala: ~]$ certutil -A -t "C,," -n 'Google Internet Authority' -d certs -i google.cert.asc After this, listing shows it trusted: ~]$ certutil -L -d certs Certificate Nickname Trust Attributes SSL,S/MIME,JAR/XPI ... Google Internet Authority C,, And mailx sends out with no hitch. ~]$ /bin/mailx -A gmail -s "Whadda ya no" [email protected] ho ho ho EOT ~]$ I hope it is helpful to someone looking to be done with the error. Also, I am curious about somethings. How could I get this certificate, if it were not in the mozilla database by chance? Is there for instance, something like this? ~]$ certutil -A -t "C,," \ -n 'gmail.com' \ -d certs \ -i 'http://google.com/cert/this...'

  • How to Reuse Your Old Wi-Fi Router as a Network Switch

    - by Jason Fitzpatrick
    Just because your old Wi-Fi router has been replaced by a newer model doesn’t mean it needs to gather dust in the closet. Read on as we show you how to take an old and underpowered Wi-Fi router and turn it into a respectable network switch (saving your $20 in the process). Image by mmgallan. Why Do I Want To Do This? Wi-Fi technology has changed significantly in the last ten years but Ethernet-based networking has changed very little. As such, a Wi-Fi router with 2006-era guts is lagging significantly behind current Wi-Fi router technology, but the Ethernet networking component of the device is just as useful as ever; aside from potentially being only 100Mbs instead of 1000Mbs capable (which for 99% of home applications is irrelevant) Ethernet is Ethernet. What does this matter to you, the consumer? It means that even though your old router doesn’t hack it for your Wi-Fi needs any longer the device is still a perfectly serviceable (and high quality) network switch. When do you need a network switch? Any time you want to share an Ethernet cable among multiple devices, you need a switch. For example, let’s say you have a single Ethernet wall jack behind your entertainment center. Unfortunately you have four devices that you want to link to your local network via hardline including your smart HDTV, DVR, Xbox, and a little Raspberry Pi running XBMC. Instead of spending $20-30 to purchase a brand new switch of comparable build quality to your old Wi-Fi router it makes financial sense (and is environmentally friendly) to invest five minutes of your time tweaking the settings on the old router to turn it from a Wi-Fi access point and routing tool into a network switch–perfect for dropping behind your entertainment center so that your DVR, Xbox, and media center computer can all share an Ethernet connection. What Do I Need? For this tutorial you’ll need a few things, all of which you likely have readily on hand or are free for download. To follow the basic portion of the tutorial, you’ll need the following: 1 Wi-Fi router with Ethernet ports 1 Computer with Ethernet jack 1 Ethernet cable For the advanced tutorial you’ll need all of those things, plus: 1 copy of DD-WRT firmware for your Wi-Fi router We’re conducting the experiment with a Linksys WRT54GL Wi-Fi router. The WRT54 series is one of the best selling Wi-Fi router series of all time and there’s a good chance a significant number of readers have one (or more) of them stuffed in an office closet. Even if you don’t have one of the WRT54 series routers, however, the principles we’re outlining here apply to all Wi-Fi routers; as long as your router administration panel allows the necessary changes you can follow right along with us. A quick note on the difference between the basic and advanced versions of this tutorial before we proceed. Your typical Wi-Fi router has 5 Ethernet ports on the back: 1 labeled “Internet”, “WAN”, or a variation thereof and intended to be connected to your DSL/Cable modem, and 4 labeled 1-4 intended to connect Ethernet devices like computers, printers, and game consoles directly to the Wi-Fi router. When you convert a Wi-Fi router to a switch, in most situations, you’ll lose two port as the “Internet” port cannot be used as a normal switch port and one of the switch ports becomes the input port for the Ethernet cable linking the switch to the main network. This means, referencing the diagram above, you’d lose the WAN port and LAN port 1, but retain LAN ports 2, 3, and 4 for use. If you only need to switch for 2-3 devices this may be satisfactory. However, for those of you that would prefer a more traditional switch setup where there is a dedicated WAN port and the rest of the ports are accessible, you’ll need to flash a third-party router firmware like the powerful DD-WRT onto your device. Doing so opens up the router to a greater degree of modification and allows you to assign the previously reserved WAN port to the switch, thus opening up LAN ports 1-4. Even if you don’t intend to use that extra port, DD-WRT offers you so many more options that it’s worth the extra few steps. Preparing Your Router for Life as a Switch Before we jump right in to shutting down the Wi-Fi functionality and repurposing your device as a network switch, there are a few important prep steps to attend to. First, you want to reset the router (if you just flashed a new firmware to your router, skip this step). Following the reset procedures for your particular router or go with what is known as the “Peacock Method” wherein you hold down the reset button for thirty seconds, unplug the router and wait (while still holding the reset button) for thirty seconds, and then plug it in while, again, continuing to hold down the rest button. Over the life of a router there are a variety of changes made, big and small, so it’s best to wipe them all back to the factory default before repurposing the router as a switch. Second, after resetting, we need to change the IP address of the device on the local network to an address which does not directly conflict with the new router. The typical default IP address for a home router is 192.168.1.1; if you ever need to get back into the administration panel of the router-turned-switch to check on things or make changes it will be a real hassle if the IP address of the device conflicts with the new home router. The simplest way to deal with this is to assign an address close to the actual router address but outside the range of addresses that your router will assign via the DHCP client; a good pick then is 192.168.1.2. Once the router is reset (or re-flashed) and has been assigned a new IP address, it’s time to configure it as a switch. Basic Router to Switch Configuration If you don’t want to (or need to) flash new firmware onto your device to open up that extra port, this is the section of the tutorial for you: we’ll cover how to take a stock router, our previously mentioned WRT54 series Linksys, and convert it to a switch. Hook the Wi-Fi router up to the network via one of the LAN ports (consider the WAN port as good as dead from this point forward, unless you start using the router in its traditional function again or later flash a more advanced firmware to the device, the port is officially retired at this point). Open the administration control panel via  web browser on a connected computer. Before we get started two things: first,  anything we don’t explicitly instruct you to change should be left in the default factory-reset setting as you find it, and two, change the settings in the order we list them as some settings can’t be changed after certain features are disabled. To start, let’s navigate to Setup ->Basic Setup. Here you need to change the following things: Local IP Address: [different than the primary router, e.g. 192.168.1.2] Subnet Mask: [same as the primary router, e.g. 255.255.255.0] DHCP Server: Disable Save with the “Save Settings” button and then navigate to Setup -> Advanced Routing: Operating Mode: Router This particular setting is very counterintuitive. The “Operating Mode” toggle tells the device whether or not it should enable the Network Address Translation (NAT)  feature. Because we’re turning a smart piece of networking hardware into a relatively dumb one, we don’t need this feature so we switch from Gateway mode (NAT on) to Router mode (NAT off). Our next stop is Wireless -> Basic Wireless Settings: Wireless SSID Broadcast: Disable Wireless Network Mode: Disabled After disabling the wireless we’re going to, again, do something counterintuitive. Navigate to Wireless -> Wireless Security and set the following parameters: Security Mode: WPA2 Personal WPA Algorithms: TKIP+AES WPA Shared Key: [select some random string of letters, numbers, and symbols like JF#d$di!Hdgio890] Now you may be asking yourself, why on Earth are we setting a rather secure Wi-Fi configuration on a Wi-Fi router we’re not going to use as a Wi-Fi node? On the off chance that something strange happens after, say, a power outage when your router-turned-switch cycles on and off a bunch of times and the Wi-Fi functionality is activated we don’t want to be running the Wi-Fi node wide open and granting unfettered access to your network. While the chances of this are next-to-nonexistent, it takes only a few seconds to apply the security measure so there’s little reason not to. Save your changes and navigate to Security ->Firewall. Uncheck everything but Filter Multicast Firewall Protect: Disable At this point you can save your changes again, review the changes you’ve made to ensure they all stuck, and then deploy your “new” switch wherever it is needed. Advanced Router to Switch Configuration For the advanced configuration, you’ll need a copy of DD-WRT installed on your router. Although doing so is an extra few steps, it gives you a lot more control over the process and liberates an extra port on the device. Hook the Wi-Fi router up to the network via one of the LAN ports (later you can switch the cable to the WAN port). Open the administration control panel via web browser on the connected computer. Navigate to the Setup -> Basic Setup tab to get started. In the Basic Setup tab, ensure the following settings are adjusted. The setting changes are not optional and are required to turn the Wi-Fi router into a switch. WAN Connection Type: Disabled Local IP Address: [different than the primary router, e.g. 192.168.1.2] Subnet Mask: [same as the primary router, e.g. 255.255.255.0] DHCP Server: Disable In addition to disabling the DHCP server, also uncheck all the DNSMasq boxes as the bottom of the DHCP sub-menu. If you want to activate the extra port (and why wouldn’t you), in the WAN port section: Assign WAN Port to Switch [X] At this point the router has become a switch and you have access to the WAN port so the LAN ports are all free. Since we’re already in the control panel, however, we might as well flip a few optional toggles that further lock down the switch and prevent something odd from happening. The optional settings are arranged via the menu you find them in. Remember to save your settings with the save button before moving onto a new tab. While still in the Setup -> Basic Setup menu, change the following: Gateway/Local DNS : [IP address of primary router, e.g. 192.168.1.1] NTP Client : Disable The next step is to turn off the radio completely (which not only kills the Wi-Fi but actually powers the physical radio chip off). Navigate to Wireless -> Advanced Settings -> Radio Time Restrictions: Radio Scheduling: Enable Select “Always Off” There’s no need to create a potential security problem by leaving the Wi-Fi radio on, the above toggle turns it completely off. Under Services -> Services: DNSMasq : Disable ttraff Daemon : Disable Under the Security -> Firewall tab, uncheck every box except “Filter Multicast”, as seen in the screenshot above, and then disable SPI Firewall. Once you’re done here save and move on to the Administration tab. Under Administration -> Management:  Info Site Password Protection : Enable Info Site MAC Masking : Disable CRON : Disable 802.1x : Disable Routing : Disable After this final round of tweaks, save and then apply your settings. Your router has now been, strategically, dumbed down enough to plod along as a very dependable little switch. Time to stuff it behind your desk or entertainment center and streamline your cabling.
