  • Automated VLAN creation with residential Wireless devices

    - by Zephyr Pellerin
    We've got a few WRT devices from Linksys here, and the issue has arisen to deploy them in a relatively small environment, However, in the interest of manageability we'd like to be able to automatically VLAN (ideally NOT subnet) every user from one another. It seems obvious to me that the default firmware isn't capable of this - can OpenWRT/Tomato/DD-WRT support any sort of functionality such that new users are automatically VLANed or otherwise logically separated from other users? It seems like there's an easy IPtables or PF solution here, but I've been wrong before. (If that seemed a little ambiguous, heres an example) User 1 sends DHCP request to server, new VLAN (We'll call VLAN 1) is created, user is placed in that VLAN. Then, user 2 sends a DHCP request and is placed in VLAN 2 etc. etc.

  • Can't Ping - Wireless network of home

    - by Naunidh
    Hello, This may seem like other ping problem, but I have tried a lot before posting it here. I have a linksys WRT54G - firmware v8.00.8. I have two laptops one windows vista (192.168.1.99) and Windows Xp (192.168.1.13) connected on WiFi . The Router's IP address is 192.168.1.4, and default gateway is the ADSL modem (192.168.1.1) connected through wire. The problem is that laptops can not ping each other, they can ping the gateway and the linksys router, and both can access internet. Following has been tried (I am pinging from XP machine to Vista): I saw that arp entires for Vista machines were not being populated, so I added static ARP entries. 192.168.1.99 00-19-7e-70-d0-4e static I checked on ethereal that an ICMP packet for MAC address of Vista machine does go out from XP machine towards the Vista machine, but never reaches the Vista machine. So its get eaten by the Router? I added Vista machine to DMZ in my linksys router, so that all the ports are open (In case it was an issue). Firewalls , antivirus etc were turned off, echo was enabled explicitly on vista, file sharing, network discovery were turned on. Network type was set to private. Unchecked everything in Router;s firewall, even though they are only meant for WAN requests. Is there anything else that I should try. Thanks.

  • windows 7 virtual wireless adapter keeps going to sleep

    - by conners
    Just a quick question that I can't see mentioned anywhere online. I have a Windows 7 box configured like these guys recommend http://www.itgeekdiary.com/windows-7-as-an-wi-fi-access-point/ simply so that I can have my Windows 7 box as a wifi access point or a wifi emitter. It's also called a Microsoft Virtual WiFi Miniport Adapter. But it powers off and shuts down automatically and stops working. Basically everything works as intended and then - well -it will stopped working when I am not at the Windows 7 PC for a long time. The problem seems to be that every time my PC goes to "power save / sleep" and in the morning the Windows 7 machine "wakes" but blooming heck the wifi has stopped and you have to power cycle the PC (which is very uncool). When I power Cycle I have to do the following as administrator C:\Windows\System32\netsh.exe wlan start hostednetwork I then tried a gazllion things involving services and power management and eventually discovered that if I run the following commands as administrator it will be ok (for a bit) but every 3rd ot 4th time I try this "trick" it simply fails. the trick that seems to work 3 out of 4 times (i.e. "most" of the time) C:\Windows\System32\netsh.exe wlan stop hostednetwork C:\Windows\System32\netsh.exe wlan start hostednetwork But why does this only work "some" of the time? What else I did by myself: on every manage adapter properties (that relates to the wifi) I right clicked [configure] [power management] /disabled/ "allow the computer to power off to save power" <- this made no difference Also (and this is a bit annoying) there is no system tray app/GUI for the Microsoft Virtual WiFi Miniport Adapter output signal ... none... so (lame as it sounds) the ONLY way I can check if it's on is to physically go to another device and SCAN.. lame so my question can probably be solved by any of the following: a) can I stop Windows 7 sleeping this wifi when the machine sleeps b) can I force Windows to force wake this process on wake? if so how? c) what is the service / process REALLY called and how do I restart it if it crashes d) how can I flush the wifi properly rather power cycle the host machine e) anyone have a link to an program or app that can sit in the system tray that shows windows 7 wifi hotspot emission status (on/off/etc etc) Since I am a programmer I can easily write a vbs script / windows exe to fix this (and I will share this solution) and the gui problem if I can work out the actual service that is running that netsh stops/starts

    My laptop connects via a wire into the modem fine and it works without any problems but it wont connect to it wirelessly, when I've taken it out places it connects fine in wifi area's! Also my son has his Wii connected wirelessly to it from his room upstairs without any problems, so I'm not sure where the problem lies, it hasn't worked since we got the modem it did on our old one and phoning Sky is just a waste of time they dont seem to know either and I just keep getting passed round departments repeating myself!

  • External HDD connecting via USB disconnects wireless LAN connection

    - by Kensai
    Strange problem. I have this MEDION Akoya PC that has a dedicated bay to slide an external HDD sold separately. It's very handy indeed cause the slot is providing a fast USB 3 connection and power to the HDD unit, without extra cables. All works fine except this show-stopper behavior to disconnect me from the router once I slide in the unit and it powers up. The moment I connect the unit the (normally) three-four WiFi connections I see in my neighborhood disappear and my own to the router loses its signal strength (no Internet traffic is possible). After a while it throws me off that one as well, never to connect me again as long as the unit is powered. Once I disconnect the HDD the various signals come back and it automatically reconnects to my own. What takes? Are we in front of a serious design fault by MEDION here? Does the spinning of the HDD on top of the PC cause electromagnetic interference strong enough to throw off my WiFi connectivity? Is it a simple USB problem? Some kind of strange hardware conflict? Where should I look?

    - by James_Smith
    Hi, Both laptop and desktop are connected to same wifi router. desktop is connected through wire and laptop is on wifi. Both Pcs are running windows 7 and can ping each other and are in same workgroup. When I try to RDC my desktop on my laptop, it connects to the desktop and shows the windows credentials screen. An admin user (J) with same password exists on both PCs. But it gives an error "the user name or password is incorrect" However when I RDC the laptop FROM desktop using the above steps..it works perfectly wel! The same credentials issue comes with Shared folders. What am I doing wrong?

  • Linksys WAP54G v3.1 no access, power and link LED solid

    - by user142113
    I'm managing the Network of a small enterprise. A Linksys WAP54G v3.1 used to provide the WiFi network. I was called, because the device did not provide a WiFi network anymore. I first of all tried to ping the device via LAN, but there was no reaction. I've frequently reconnected the AP to the mains and always the POWER and the LINK LED keep solid, even if no network cable is connected. What I've done yet: Reset as documented: Pressed the RESET button for 10 seconds. After that I have tried to access the AP with a direct cable connection to my computer, that I've set to a static ip of 192.168.1.240, but i got no ping response on the default IP 192.168.1.245. Furthermore ipconfig reports "media disconnected". More complex reset method as described here http://bruceshankle.blogspot.de/2005/12/how-to-reset-linksys-wap54g.html as well had no effect. also tried to ping 192.168.1.1 without success Tried this method: http://www.daniweb.com/hardware-and-software/networking/threads/142437/linksys-wireless-access-point-problem#post680245 but there was no ping response when powering up. As well the tftp transfer timed out Finally tried to short pin 15 and 16 of the flash chip on the bottom side of the AP mainboard while booting to provoke a Checksum error. This should lead to the possibility to upload a firmware with tftp, as the AP stops booting and waits for a tftp connection on 192.168.1.1. But I've had no success. As well i've put pin 15 and 16 to ground while booting, also without an effect. After all that I still can't ping the AP, ipconfig still tells me "media disconnected". The POWER and LINK LED are solid. I would appreciate your answers

  • Outdoor WiFi Mesh Topology vs. Repeaters

    - by IronJaxor
    Here's the current configuration in our organization (which I believe is incorrect): We have a number of Cisco 1500 series AP's (22 in total), that are mounted outdoors to provide seamless WiFi coverage over a large area. Each AP however has its own physical ethernet connection back to the WLC (All the AP's are marked as Root AP's). They are all broadcasting the same SSID. We have tried to stagger the channel selection but because there are only three non-overlapping channels to choose from, and in some areas the density of AP's is quite high, there is multiple places of channel interference. With this configuration we experience 100-150 disconnects from clients every day. (Our clients are mobile so they move throughout the coverage area constantly). My idea is to switch the AP's to the same channel thereby forming a wireless mesh, use the built in functionality of the 1500 series to use 802.11a as the backhaul, designate one or two AP's as root AP's and wire them back to the WLC. Thereby forming a WiFi mesh, which if I'm not mistaken is the point of the 1500 series in the first place! I am however completely new at WiFi networks and wondering if I am simply mistaken in what I believe my proposed changes will enable, or if there is a better way to tackle the WiFi topology.

  • Connecting a Wifi router to receivers with a cable instead of antenna?

    - by 31eee384
    This is a very strange question--I'd go so far as to say it's a stupid question. I'm being told that it is possible to, to describe it briefly, use a cable to connect an access point and a receiver directly to one another. This means that I would unscrew the access point's antenna, and attach one end of a cable to the port. Then, on the wireless receiver, I would also unscrew the antenna and plug in the other side of the cable. I'm being told the connection would work after this, just as a normal Wifi connection would. Bonus mini-question: if this works, would it still work if a splitter were attached to the access point and multiple receivers plugged in to the network? What would happen if I do this? Based on my surprisingly deficient knowledge of radio transmission, I don't think it would work. I would like some help knowing why it won't (or will) though, if possible. This is a somewhat hypothetical question--I realize that Ethernet does this exact job very handily, and I could just throw in a switch instead of the splitter. I simply feel that I should understand this scenario. Thanks for any help you can offer.

  • why would resetting the Netgear N300 router fix my Win 7 laptop's slow wifi?

    - by rjnagle
    In the past day the wifi download speeds of my Win 7 HP 64 bit laptop have slowed considerably. I am trying to troubleshoot the problem and to figure out whether it's hardware related (i.e., is the Intel(R) Centrino(R) Wireless-N 2230 the problem?) or router related. I have a Netgear N300 router connected to my modem. I'm using Speedtest to measure my speed. First, during my problem state, my ipad can download and upload at normal speeds. It's only my Win 7 laptop which is having problems. Because my ipad downloads at normal speeds, that would tell me that the problem is specific to the laptop (either HW or SW). But when I restarted my Netgear router, the laptop wifi problems disappeared. That just doesn't make sense. If we know that one device can connect properly to the router, why would a laptop have problems? What are some possible reasons why this might happen? Also, during my problem state, I noticed that on my laptop upload speeds were faster than my download speeds. Anybody have a guess about what might cause upload speeds on one device to be faster than another? Is there any actions i could take (or options to enable) so this problem won't occur. (I initially thought my problem might be software related or memory related -- Norton AV or browser plugins. But even after I disabled everything and made sure memory footprint was minimal, the slowdown was still occurring -- and it solved itself altogether when the router was reset).

  • Is WEP used in conjunction with a wireless access list adequate security?

    - by LeopardSkinPillBoxHat
    I use a Netgear wireless router, with various wireless devices connecting to it. One of my wireless devices doesn't support WPA2 security, so I had to downgrade the security on the router to WEP. We all know WEP is broken, so as an added measure I enabled a wireless access list on the router so that only devices with specified MAC addresses which are in my access list are permitted to connect to the router. I know it is possible to spoof a MAC address from a device for the purposes of accessing a secure network like this. But is it easy? Is using WEP and a wireless access list good enough to prevent most hacking attacks? Or should I do whatever I can to ensure all devices support WPA2 in the future?

  • Can my ISP find out if my wireless is protected or not?

    - by Zakukashi
    Im just wondering how much my ISP knows about my activities. I have a Modem from them this modem then connects to a SITCOM wireless router which then leads to MY PC's, Phones, Laptops. I really need to know if my ISP knows if my router is in unprotected state of wireless or not. The Sitcom box it not theirs, we payed for it long after getting this internet. Does my Sitcom wireless router send data to my ISP on its own, indicating delicate information such as wireless protection on or off? Or does the ISP's modem fish out this information on its own since our wireless router is connected to it? Would greatly appreciate any answer.

  • Mouse/Touchpad not working in Mac OS X Lion Pre-Boot Authentication (PBA) with File Vault 2

    - by Chris
    I set up File Vault 2 in Mac OS X Lion with Pre-Boot Authentication (PBA). In PBA-login my USB-keyboard is working, while using a wrong keyboard layout. I can neither use my magic touchpad nor an USB-mouse in PBA. Thus I can't change the keyboard layout located in the upper right corner. I tried unplugging all USB-devices except keyboard and mouse. Nothing seems to help and the mouse cursor isn't moving. How can I get magic trackpad or USB-mouse to work in PBA login screen or manually set the used keyboard layout in PBA? Update: Still no (USB-)mouse or bluetooth trackpad support in File Vault 2 Login Screen. Today I talked to Apple Support for over one hour with no result. Every idea is appreciated.

  • wireless printer - entering WPA - is there a quicker way?

    - by camcam
    I have a wireless printer (Brother DCP-585CW). The wireless setup instruction says I should enter the WPA key to the printer. The key is entered using up and down buttons on the printer. So, I am supposed to enter 64 characters using up and down buttons. To enter 1 character, it takes on average (24+10)/2 = 17 times pressing the button (digits start after 24 letters). So 17*64 = 1088 times. Is there a quicker way to setup a wireless printer? Maybe there is a Windows program that discovers printers connected to computer through USB or Ethernet (my printer has both sockets) and allows to pre-configure it for wireless usage (enter the long WPA key)? Update There is BRAdmin program and it allows to set up almost all wireless settings... almost - all except WPA :(

  • jQuery: Is mouse over element?

    - by JamesBrownIsDead
    I could write something pretty easily to determine whether the mouse is over a given element, but is there already anything in the jQuery core library (or a plugin I guess) that will tell me whether the current mouse position is over a given element?

  • Help finding a USB Joystick mouse?

    - by shane87
    I am currently developing a final year project which involves using a joystick instead of the mouse for those who are physically impaired. Does anyone know where I can find a USB Joystick mouse? All I can find on e-bay and amazon is very sophisticated flight joysticks with loads of buttons and controls etc. I am looking for a plain and simple joystick? If anyone could point me in the right direction I would be very grateful.

  • Monitor USB optical mouse activity for movement and call a program on Windows

    - by CheeseConQueso
    I'm essentially looking to monitor a USB port input for whatever happens when the optical mouse detects its own movement and turns itself on. These mice usually have a dim red light when in "standby" mode and then the red light becomes brighter once you start moving it around. I want to use Visual Basic or something else native to the Windows environment to open an exe file or play a wav sound or call a bat file when the mouse "wakes up". Any suggestions or pushes in the right direction are appreciated.
