• Router drops internet connection if I connect an additional pc

  - by BluePerry

  Hey, I'm using a SMC2804WBRP-G router connected to my ADSL-modem. Usually there are two computers connected to this router: a win7 ultimate desktop(wired) and a macbook air (wireless). Both working absolutely fine and never caused any connection drops as far as I know. A new room mate moved in last month and each time she starts up her win7 home laptop the router looses the internet connection. The laptop is on a wired connection. The first time she connected to my router, the connection dropped every 2 mins. To find out whats wrong with her machine I disabled all unnecessary services etc. besides the anti virus software. That helped to eliminate almost all of those periodic connection drops. But the start up drop remained and I've got the feeling that the router is still loosing connection from time to time. I haven't had the time to find out what service caused the periodic drops. But I'm more concerned about is that start up drop. Can anyone point me in the right direction to look for the problem? I would be very thankful for any hints or tips!

• Resolving loss of internet bandwidth in home network

  - by Caspar

  Recently, I've decided to connect my laptop at home to my modem/router through Ethernet cables built into my apartment. As these built-in Ethernet cables are usable via plugs built into the walls (called powerline adapters), I use some additional cabling (STP CAT6 cables) from my laptop/router to the plugs. In addition, I don't know any technical details about these built-in cables (as they're not visible), only the maximal bandwidth (1 GBit = Cat6?) that they're supporting. The built-in cables are Cat. 5e Ethernet cables. The problem is now that when I set up the connection, I cannot use the full bandwidth that my internet connection is actually offering (100 Mbit/s), only about 85 Mbit/s between 85 - 88 Mbit/s, despite the fact that all cables involved should support the maximal bandwidth. I know from other tests with one of the Ethernet cables in use that I can use almost 99 Mbit/s when I connect my laptop directly to the router/modem using only this one cable. In addition, it is very unlikely that the length of the resulting cable connection from my laptop to my router involving the built-in cables exceeds 100 m. So, what possible reasons for this loss of bandwidth exist? And how I can fix this issue? I hope this might help resolve the issue: The built-in cables appear to be Cat. 5e Ethernet cables. So, is there any problem when I connect Cat6 Ethernet cables directly to Cat5e Ethernet cables via the plugs?

• File ownership and permissions on web site PHP files

  - by columbo

  Hello, I am learning the basics of linux servers so I am green. I have an Ubuntu server upon which there are websites that I have inherited. In a fit of security worry I decided to check out the ownership of the web site files. They are all 2016:sites. If I run the command 'cat /etc/group | more' I can see that the group exists. But when I run 'lastlog' the user 2016 does not appear. I started to worry that 2016 might be the username of web users connecting from the web so I set the permissions on a testfile to chmod 600, giving read permissions to only the file owner. Sure enough I could still access the file from the web. Can anyone suggest what is going on here? I tried creating a new user and giving them file ownership but then when I access the file from the web it wants me to have all directories up stream owned by the same person. Thanks

• How do you enable view source in ie8 when it gets magically diabled

  - by Tim Meers

  I have multiple computers that all seem to have View Source disabled from the content menu when you right click on a web page. Now I know it's not that the web page is some how disabling it, I'm pretty sure thats not even possible. But alas I have at least 3 machines in my office (not on AD) that have this problem. I have also worked on clients computers that have this same issue. It's down right maddening! I tried to Google for it, but it just shows results from the dawn of IE6 in all of it's "glory" with a bug where if the cache was full it would be disabled. But this is not the case in IE8. Any body have a clue why this is happening, or a fix for it? Maybe a reg setting? Update: So I got a little closer to solving it, but there was still an issue on one computer where it allowed it not is HTTP, but not in HTTPS. One other computer works correctly in both. I Found these two keys missing in the registry: [-HKEY_CURRENT_USER\SOFTWARE\Microsoft\Internet Explorer\View Source Editor] [-HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\View Source Editor]

• Best way to troubleshoot intermittent network outages?

  - by Ben Scheirman

  We have a Comcast 50/10 line into our office. We keep seeing very short but sometimes frequent drops in our internet service. It's enough to kick you off of skype and stop any websites from loading, which is obviously affecting our productivity. We've tried 4 different routers, we've tried moving everyone off of wireless and onto wired via a switch and so far nothing has helped. Right now we're on a Cisco SB WRP400-G1 router. Attached to the router is a 16 port switch going to the ports in all of the offices. We've moved to OpenDNS in the case that it was the comcast DNS servers going down. Today we tried putting the modem, router, and switch on a UPS to make sure it wasn't power fluctuations that was causing it. Every time we call Comcast, by the time they are here the internet is working fine. I'd like to somehow prove that the problem is with Comcast, so if that means plugging in a machine directly into their router and collecting data all day, I'm up for that. I just want to hear ideas on what tools to run and how to collect this data. I could just continuously ping google.com all day long but I'm not sure how valuable that data would be. Thoughts?

• Client unable to access OWA website after temporarily changing SSL certificate on the server

  - by Lorenz Meyer

  I have the following issue: One client computer (Windows XP) cannot access the OWA website. All other client computers can (Except another one in the same remote office). How this happened: I temporarily changed the SSL certificate on the Exchange Server yesterday. After a few minutes, I reverted back, an now the same certificate that was installed for years is back again. During these few minutes, they were in OWA on this computer and got a certificate error. What exactly happens: Internet Explorer displays the error Internet Explorer cannot display the webpage, Firefox displays The connection was reset and Crome shows This webpage is not available. The connection to ... was interrupted. What I already did to try to get this working: Restart the client computer Restart the exchange server Deleted Internet Explorer browsing history In IE, Internet Options, tab Content, under Certificates deletes SSL cache Restored Internet Explorer to the default parameters I looked into certmgr.msc, but did not find a certificate related to the issue What could I do else to narrow down the origin of this problem (or better: resolve it) ? Can you give any advice ?

• Internet Troubles - PPPoE vs PPPoA?

  - by AkkA

  I have been having some internet troubles at home (ADSL2+ connection in Australia). We get random drop-outs from the authentication connection. It will keep the connection to the DSL service, but we lose authentication and either have to restart the router/modem (its combined, a Belkin one, not sure on model number) or unplug the phone cable, wait about 30 seconds and plug it in again. I've called the ISP (Telstra) a few times, but they only offer limited support when we dont use their supported hardware. Apparently something had happened on their side, they checked the box again (at least it sounded that simple), and told me it would be fine. It wasnt. I've replaced all the filters around the house, but that didnt help either. We do live a little bit away from the exchange (get a sync speed of about 3000/900), so I thought it could be due to line noise but that hasnt helped. Telstra allow both PPPoE and PPPoA connections (which I'm configuring through my router, dont have software on the PC side). I've been running PPPoA the whole time, would it make any difference changing it to PPPoE? If not, are there any other theories as to why we would be experiencing these drop-outs? It has been fine for at least 12 months, then suddenly started about 2 months ago.

• Lion MacBook Pro will not load webpages with DNS just after wake

  - by NReilingh

  I'm working with a 2011 MacBook Pro running Lion (10.7.2), that after waking from sleep (i.e. opening the lid) takes an inordinately long amount of time (2-3 minutes or more) to get a usable internet connection. Upon waking, the wi-fi icon signifies it is negotiating a network connection, and completes one a few seconds later. At this point, network diagnostics will not show any issues, and everything in Network preferences looks as normal: I'm connected to the proper network, have the right IP address and gateway, and DNS settings are correct. However, any site accessed with a domain name (like http://www.google.com) in Safari will return the "You are not connected to the Internet." error. Accessing a site directly, say, with Google's 74.125.226.212, is successful. Yet, Network Diagnostics will insist that DNS is functioning properly. After a few minutes, the following lines will be printed to the Console log, and regular behavior will be restored. 11/18/11 8:11:31.288 PM airportd: _doAutoJoin: Already associated to “Wireless”. Bailing on auto-join. 11/18/11 8:11:32.000 PM kernel: en1: BSSID changed to 00:25:9c:63:91:bd This behavior occurs only when waking from sleep--not when turning wi-fi on and off. This problem also occurs when using a wired Ethernet connection. As per this thread, I have tried flushing the DNS cache and wiping the wireless network from memory (it's not a protected network). Neither have worked.

• Synchronize folders on different computers without cloud and without network just internet

  - by theimmortalbg

  I have two computers with windows 7, one in my home town and one in another town. So they are not in private network but I have internet on both. They have exactly the same file structure. I am searching for program that can keep the data equal. I know about dropbox or google drive but they are cloud and I don't want to use them. Also they are using folder that you should copy your data in it. There is another programs that are like a server, just put something and after that you can download it but I dont need them. I want just to point which folders to be synchronized and the program make the synchronization. The sync can be in real time if the two computers are powered, or after few time when they are powered. Or it can lock another computer synced folder till update is required. At all this is my documents that I want to be synced in all my computers and to be changed from where I want. In fact I can move the updates with flash but if some program save the changes and make them on another computer with one click it will facilitate my work.

• Installed IE8 & SP3 on XP now I can't HTTPS from any browser.

  - by Kevin

  The computer is Windows XP Professional SP3 with IE8. On the Tools Options Connections the "Settings" is GRAYED OUT (I am an admin on the machine) Any browsing of https:// addresses results in IE displaying the following: "this program cannot display the web page" After installing an alternate browser and trying the same https:// address I get a similar error message. I have tried using Compatibility View Settings to for all web pages and this has no effect on the problem. HTTP addresses work fine, I can PING sites such as google.com without issue. Question: What could be preventing me from getting at the settings to check to see if I'm using a proxy? What else could be preventing HTTPS access?

• Allowing access to company files accross the internet

  - by Renaud Bompuis

  The premise I've been tasked with finding a solution to the following scenario: our main file server is a Linux machine. on the LAN, users simply access the files using SMB. each user has an account on the file server and his/her own access rights. user accounts are simple passwd/group security accounts, not NIS/LDAP. The problem We want to give users (or at least some of them, say if they belong to a particular group) the ability to access the files from the Internet while travelling. Ideally I'd like a seamless solution. Maybe something that allows the user to access a mapped drive would be ideal. A web-oriented solution is also good but it should present files in a way that is familiar to users, in an explorer-like fashion for instance. Security is a must of course, and users would be expected to log-in. The connection to the server should also be encrypted. Anyone has some pointers to neat solutions? Any experiences? Edit The client machines are Windows only.

• DSL Connection drops

  - by user60024

  Ok, I just moved so I had to switch from Cable to DSL. I know very little about computers or internet connections and such, so I had AT&T come out to the new house to set up their highest speed. When they got here, they told me that I needed to downgrade to 3.5mbps because I was too far away. Well we did and everything was going great for two days until I started experiencing random disconnects which have been happening now for about 2 to 3 weeks. I am using a N300 Wireless Dual Band ADSL2+ Modem Router and my ethernet cable is hooked directly into my computer from it. I recently started to notice that it disconnects around 5:30 and 8:30, which may be because a lot of people are on their computers(?) and that it works perfectly fine, almost, all the time if I'm not playing a game. During this time, when I try to load up World of Warcraft the Internet light disappears and the DSL light begins blinking. (So maybe it's too much for the modem and it resets?) Other than that it is amazing, but I'd like to try and fix some of these problems. If you need more information, let me know on how to get it for you and what to do. Thanks for the help!

• Does ICS modify windows firewall policies in the registry?

  - by insipid

  I had a host machine I wanted to enable ICS on. First I realized that doing so was not possible until I enabled the Windows Firewall. Once I enabled the firewall and set up ICS, I noticed due to group policy I could no longer disable the firewall. Also, any ports I tried to open seemed to be ignored. Although nothing seemed to be configured when I used the mmc snap-in to view local computer policy, when I checked the registry I noticed several policies set there in HKLM (such as disabling AllowLocalPolicyMerge). I was able to remove the policies from the registry and my open ports worked, but they were eventually re-added without my input. The network I am sharing the internet from is an "unsecured" wireless network with an authentication page, is it possible that this is causing those policies to be set? Did ICS set those policies? When you go to the properties of the ICS enabled adapter and go to the ICS settings it takes you to a tab called services where you can add and remove "services running on your network that internet users can access". Is this related to the windows firewall?

• Credentials needed for BT line on Netgear router

  - by Bali C

  I have recently bought a new Netgear router to replace my current BTHomeHub as it doesn't support wireless. I did buy a WAP but figured it would be easier to use a router with wireless built in. (It's a modem/router combo). I have got as far as setting up the router on the web interface, but then it asks for a username and password to connect to the net, I can only assume this is for the phone line? I have tried some passwords I could find written down but they don't work, the internet light comes on and then when the creds fail it goes off. I have been on the homehubs web interface and been through all the settings it has to find the credentials it is using which obviously work, but no joy. Is there anything obvious I am missing, or is there a way I can retrieve my settings from my existing router? Any pointers will be very appreciated.

• Two internet connections at once in Windows 7

• KVM virtual machine unable to access internet

  - by peachykeen

  I have KVM set up to run a virtual machine (Windows Home Server 2011 acting as a build agent) on a dedicated server (CentOS 6.3). Recently, I ran updates on the host, and the virtual machine is now unable to connect to the internet. The virtual network is running through NAT, the host has an interface (eth0:0) set up with a static IP (virt-manager shows the network and its IP correctly), and all connections to that IP should be sent to the guest. The host and guest can ping one another, but the guest cannot ping anything above the host, nor can I ping the guest from anywhere else (I can ping the host). Results from the guest to another server under my control and from an external system to the guest both return "Destination port unreachable". Running tcpdump on the host and destination shows the host replying to the ping, but the destination never sees it (it doesn't even look like the host is bothering to send it on at all, which leads me to suspect iptables). The ping output matches that, listing replies from 192.168.100.1. The guest can resolve DNS, however, which I find rather odd. The guest's network settings (connection TCP/IPv4 properties) are set up with a static local IP (192.168.100.128), mask of 255.255.255.0, and gateway and DNS at 192.168.100.1. When originally setting up the vm/net, I had set up some iptables rules to enable bridging, but after my hosting company complained about the bridge, I set up a new virtual net using NAT and believe I removed all the rules. The VM's network was working perfectly fine for the last few months, until yesterday. I haven't heard anything from the hosting company, didn't change anything on the guest, so as far as I know, nothing else has changed (unfortunately the list of packages updated has since fallen off scrollback and I didn't note it down).

• IIS7.5 is only resolving to the Default Web Site

  - by Dennis Burnham

  I am able to access only the Default Web Site on a Windows 2008 R2 Server which is running IIS 7.5 The Default Web Site's binding is to "All Unassigned", same way as I have done it on a different machine running IIS6 under Windows 2003 Server. The bindings of the desired Web Site have the IP address of the server and the correct home directory. Regardless what I do, the only page content I can see is the default index page in the wwwroot directory which is the Default Web Site. What must I do to deliver the correct content from the Web Sites that are configured in IIS7.5?

• map linux drives to windwos 7 for media stream over internet

  - by Ortix92

  I'm trying to map a linux network drive to my windows 7 laptop, however this laptop is not on LAN. At home, I simply use Samba, but this obviously won't work over the internet. I'm trying to avoid VPN, so if there are other solutions, I would like to know about them. The reason I ask is because my university does this as well. We can simply map folders to our computers without VPN connections. I'm not sure what they are running as servers. The main reason is because I want to be able to access my files stored on my home server wherever I go. They are located in the /home/ folder (videos, music and pictures folder). I'm trying to keep my websites and media separate from each other. I wouldn't mind accessing them from a web interface either, but I would like to keep the directory structure intact. I remember having an app like that come with winamp and running it on my windows pc (As the server). Unfortunately it doesn't work for linux. Any ideas on what I could use? Would XBMC be able to help me out with this? I did do some researching but I couldn't find any concrete answers

• wireless to wired internet

  - by Mark T

  My wife uses an old computer which doesn't really like having an internet connection via a USB wireless adapter. I've tried several, and none have been satisfactory. The connection gets dropped often and it is frustrating for her. A wireless card also had the same trouble. Repositioning the computer made no difference. (Two laptops, nearby, connect just fine and stay up, so it isn't the router.) However, the computer always worked well when I had an Ethernet cable connected to it. I know there is a box which will connect to my wireless network and provide an Ethernet cable connection. But the terminology used is so complex, I can't tell what it is I really need. In case that wasn't clear, here it is in different words: What I need is just the opposite of a wireless router. My wireless router takes my cable modem's Ethernet connection and makes it available to wireless clients. What I want is a box which is a wireless client to my wireless router and provides an Ethernet cable connection that I can connect to any device. I need to know the right name for a box with such capabilities. If you know of some inexpensive examples, that would also be helpful. I'm running a wireless G network with a Linksys Router.

• Windows 7 'Unidentified Network'

  - by Throdne

  So my internet was working last night before I went to bed and woke up to a computer that is showing unidentified network. I have tried multiple ways of fixing it. > route delete 0.0.0.0 > uninstalling drivers - restart - reinstall from downloaded drivers > ipconfig /release - /renew > static IP > speed & duplex from auto negotiation to 1.0gbps full duplex > and also changed my network address to no value to 1234567890ab (not in that order) nothing seems to work. I have Comcast internet and when I connect the computer to the modem it works perfectly. but when I connect it to my router again, Unidentified network. I know my router isn't faulty, because my macbook pro, server, NAS, iPhones, and iPads are still working. I have also tried moving the port on the router, still same problem. my router is a: Cisco Small Business RVS4000 motherboard: GIGABYTE GA-990FXA-UD3

• Mount linux partition as Windows network share over internet

  - by CptEO

  I have a Linux server running RHEL 6. I have two Windows servers. All servers are connected directly to the web with an external IP, they are not in a local lan. What I would like to achieve is to setup the Linux server so that it offers a single share (the whole partition) that can be mounted as network drive within Windows. I don't want to use any 3rd party software to access the linux server because I want to use the linux server as a backup for Bare Metal Restore. In order to do so, I need to be able to access the linux partition from within the Windows Recovery Enviroment where I cannot install any 3rd party software. The linux server should only be accessible from given IP addresses (e.g. the 2 windows servers). Does anyone know if the setup I would like to have is possible?

• How to change the MAC address in Win 8 to spoof a Roku Player through a WiFi splash page?

  - by luser droog

  My Linux laptop died yesterday and now I can't watch TV. Let me explain. I use a Roku Player to stream Netflix shows to my television; and a year or two ago, the Internet Service provided in my apartment complex added a Splash Page to get through the router and onto the net. After not too many days, I remembered that internet devices identify themselves with a MAC address. So I delved into the manpage of ifconfig and discovered that I could persuade my laptop to pretend to be the Roku Player, connect, click through the Splash Page, disconnect and change it back. This would allow the Roku to connect for about 24 hours, when I would have to do it again. But the laptop died yesterday during my smoke break. So during lunch, I ran to OfficeMax and got a new one. But I don't know where to begin looking for where to change the MAC address (assuming it's possible). I know I can try dual-boot, or a keychain OS, or possibly other things to resurrect my old method. But, is it possible to get Windows do it?
