Internet Connection Stopped Working On Desktop PC?
Nov 19, 2012
I've been happily using a desktop PC wired into a router (using an ethernet cable) as well as a laptop that connects wirelessly to the router. This setup has been working fine since I started with it a few weeks ago.
On Friday evening the desktop PC stopped being able to connect to the internet and hasn't been working since. The laptop is able to connect fine wirelessly.
The router light seems to indicate that the ethernet connection is ok. I've tried connecting wirelessly from the desktop PC but that doesn't work either - the Netgear wireless usb adaptor won't open from within Windows as it usually would do.
Nothing has changed to the hardware setup (I've checked all connections) so I wonder if this is a software problem caused by a virus or maybe by Windows updates?

My computer stopped being able to Remote Desktop to my server on my network. My backup software also doesn't recognize my server. But, I can access its folders using Windows Explorer. Any other PC on the network can remote desktop to the server and connect. What happened to my machine? This message appears when i try to connect: "Remote Desktop can't connect to the remote computer for one of the following reasons:
1) Remote access tot he server is not enabled
2) The remote computer is turned off
3)The remote computer is not available on the network
Make sure the remote computer is turned on and connected to the network, and that remote access is enabled."
My computer is:
AMD: Athlon 64 X2 5200+ 2991 MHz
Mobo: Gigabyte M57SLI-S4 v.2
RAM: 4GB Mushkin DDR2 PC2-6400
OS: Win 7 64bit
VC: Geforce GTX 470

recently my network adapter just stopped working. The wifi signal was really bad so i unplugged it and when i plugged it back in it doesnt even turn on. I've reinstalled the drivers and still it doesn't turn on. In device manager there is a yellow exclamation mark next to it and when i click on properties it says code 10. I used it on my laptop and it turns on but when i plug it in my desktop it doesn't seem to turn on.

The other day I went to a friends house, came back home, booted up my PC, and my wireless network adapter wasn't working. I've tried everything to fix it.It's a D-Link DWA-525 802.11n Wireless PCI netowrk adapter. On device manager it just says 802.11 Wireless LAN Card with a yellow exclamation next to it. And when I check what the error is, it's either error 31 or 52 at different times, depending what I've tried to do to fix it.I tried downloading the driver for it off the D-Link website, nothing happens at all when I install it. I tried taking it out of my computer and plugging it in. I tried enabling it and disabling it on device manager.I noticed one thing, when it's in my computer the green light at the back that says activity next to it isn't on.

I Have a HP dc5000MT desktop. I run an ethernet cable from its network card {Broad NetXtreme Gigabit} to a Westell 327W router{this has worked for the last four years}. My laptop connects to the internet through this router using wireless and for test purposes through the ethernet port. I installed a new network card {Dynex DX-E102 PCI NetworkAdaptor}in the desktop. When i'm enabling either the old or new card through Control Panel, Network Connections, i get the message "acquirin network address,Firewalled".and it never enables. I ran Malwarebytes and no infections were found. I use AVG anti-virus and Internet Explorer.

I own a laptop and a desktop, and I use my DIR-600 to connect them both to the internet, using a PPPoE connection. After "repairing" the Desktop (by booting via Windows XP CD) my PC just stopped connecting to the internet. I had rested the router, then configuring it again. Still same issue. Wireless works perfectly. Direct connection.

"Ethernet Connection has stopped working".Its stopped working again and I've run the Network Test and the results are in the file REG.txt attached. I can connect to the internet via wireless OK but I had wireless turned off to run this test.I've proven the ethernet cable OK by connecting another pc to it which works OK.

I have an ASUS X58C laptop which has been working OK to the internet via the ethernet cable but it has stopped working.I used the laptop via the wireless connection to access the internet while away from home and on my return I can not connect via the ethernet but I can connect OK via wireless. The results with the wireless enabled are :
C:>ipconfig
Windows IP Configuration
Ethernet adapter Local Area Connection* 13:
Media State . . . . . . . . . . . : Media disconnected
Connection-specific DNS Suffix . :
[code]....
I can see that the ethernet adapter(s) are shown as media disconnected but I don't understand how to make them connected. I also don't understand why there are two ethernet adapters or what the Tunnel Adapters are.Before I did the ipconfig command I went into Control Panel/Device Manager/Network Adapters/SiS Ethernet Controller, right clicked and selected the Update Driver Software which searched the internet for a driver and installed it.

My internet went down temporarily last week and ever since my computer has not been able to maintain a connection. It will pick up the signal intermittently but produce painfully slow internet and then promptly lose the signal all together. The wireless connection is working perfectly on laptops and smart phones, even when in the same position from the router as my PC.
Router: Netgear Dg834Gv3
Wireless Adapter: Netgear WG111v3 USB
Computer: Dell Vostro 200
ISP: AOL

I have the WRT54G router for years and use it to provide both a wireless network for our home computers and a wired network for by internet phone that connects me to my office phone system and for my work computer and printer. Last week, the wired network stopped working. I checked the wiring and plugged my wire into all four of the ports in the back of the router with no success. I followed the troubleshooting procedure that I found and changed the MTU setting. I tried to update the firmware but the screen seemed to lock up and I was unable to complete the task.

I've had the WRT400N for about a year and a half now and just last night it stopped sending out data when connected to my cable modem. I've tried connecting the modem directly to my Mac and it works just fine (that's how I'm sending this message now). But when the modem is connected to the router, I get no data. It connects to both the 5 Ghz and 2.4 Ghz networks, but it refuses to send data through the pipe. I've tried power cycling both the modem and the router to no avail.

I have an HP/Compaq laptop that is quite a few years old but has been working fine. It has stopped connecting to the internet although it will connect to my wireless network. The internet works and all other devices (my tablet, my phone, daughter's laptop, etc) all connect. The laptop started having troubles recently and would eventually connect to the internet if I rebooted a couple of times. However, I've been trying multiple times today and it still won't connect.I have Windows Vista and the repair function has not fixed it or diagnosed the error.

I don't know how to copy / paste the ip config so I ss'd it:(url) internet provider is RCN, I have AVG and Malwarebytes installed, I've tried disabling them both and didn't fix it! Anyways my internet was working fine, until one day it just suddenly stopped working. We have multiple computers hooked up to the network (5) and all work except mine. This same problem happened to my sister's computer, she has almost the same model as mine. We fixed it by switching it to wireless, but I was wondering if there was any way around that. It's a HP Pavilion. The box thingie lights up green and everything. I can access the other computers through the network, it's just the internet that won't work.

I have a new Alienware X51 running Win 7. It's connected to a home LAN, both wired and wirelessly. For the prior two days internet connectivity has been fine. Today, the PC will not connect to the internet. The Network and Sharing center in control panel shows that the PC is connected to both the wireless network and the wired network, but with no internet connectivity. All other computers and devices in the house are able to connect to the internet. Tried restarts, virus scans, router power off/on, ipconfig /release and renew, all with no luck. When I try and ping other computers in the LAN or the router I get a "General Failure" message.

I got the computer in 09 with windows vista and the internet worked correctly. i upgraded to windows 7 in 2010 or 11 and the wireless was still working. Last year all of a sudden my wireless internet stopped working and had to use a cable to connect to my router. A few months went by and i randomly got my wireless internet connection back for about 2-3 months now all of a sudden my wireless is out again. i ran tests in other threads posted on this subject and the only way they got it to work was to buy a usb connection. is this the only way im going to be able to get wireless back?

I have an old Gateway W322 laptop running Windows XP Home Edition and it recently stopped being able to connect to the internet. It happened gradually, at first having connection problems off and on for a few hours, and eventually it would no longer connect at all. I tried using an ethernet cable to the modem and that didn't work. I also know it's not my modem because I have other computers in my house and they are connecting just fine.

I have a samsung 365E5C-S02 Laptop running Windows 8. The internet worked just fine until yesterday when it stopped working. Now I can connect to the wireless network just fine but no internet. Several other computers work on the same wireless network. I ran the troubleshooting sequence at "control panel-> troubleshooting -> network and internet " but it didn't find anything.

I purchased an e4200 about 6 months ago and it worked great until the other night the Internet stopped working on my laptop (wireless). I tried unplugging both my modem (Motorola Surfboard) and router and plugging them back in, but no luck. I can accesss the Internet when plugged directly into the router (with both my PC and laptop), so it looks like the issue is with the e4200. To make matters worse (and I fear much worse), I can't even access the admin page to the router through either the Cisco Connect software or through the IP address. I've tried resetting it, I've tried the 30/30/30 reset (holding the reset button while doing an unplug and pluging back in), and reinstalling the Cisco Connect software, all to no avail.
I've found threads where others have not been able to access the admin page, but they still had access to the Internet url... I haven't found a similar thread where the router doesn't seem to work at all. A few other bits of information I can think of (let me know if there's other information I can provide):The Cisco logo light flashes slowly after reset which I believe is expected.The lights in back of the router seem to work as intended.Running Windows 7 Diagnostics finds the connection "doesn't have a valid IP configuration" and "The default gateway is not available."

I have a HP desktop Pavilion p6531 p-b (Windows 7) that is hardwired to a Linksys 2500 Router. Internet worked fine until this morning where it can't connect at all. It can pick up the Wireless connection from the router but I can't get it to go online even wirelessly (although I am not sure if I'm doing that part right). I called my ISP and they reset the modem, etc as well as bypassing the router and we still cannot connect to the web. We looked at the Network Center and made sure that in the Local Area Connection, the Internet Protocol Version properties all have "Obtain address" and "Obtain DNS server" automatically checked. At that point their tech support was stumped.

I have recently upgraded my router to a Belkin N750 DB and am having issues getting remote desktop connection working. Previously I had a Netgear router and it was working no problems at all.I have port forwarded (virtual server on Belkin) port 3389 TCP to the servers IP address.I can get Remote desktop connection to work when I am within my LAN by just typing the computers name.However when I try to connect via the IP address, as I would if I were away from home, then I get the message that says "remote desktop cannot connect for one of these reasons
1) remote access not enabled (it is because it worked before)
2) remote computer is turned off (no it isn't)
3) remote computer is no available" (yes it is cause can connect from LAN)
Turned off static IP for my server and let the router assign IP, and changed the IP address in the port forward, same, no connection.Double, triple checked my IP address, as this obviously changed when I plugged in the new router.Have updated to latest firmware for router and NIC.

I am having wireless connection/internet issues that are irritating me to the core!!! I have called tech support 4 times now, and I still can't get everything to play nice...I have the 655 set up as a wireless router to a Windows 7 laptop, one iPad, two iTouches, and one N3DS. I can't find a setting that will work with all devices. Here are the senarios...
1) Settings: Wireless enabled, 802.11n only, Auto Scan off-channel set to 1, Best Transmission rate, Channel Width Auto 20/40, Visible, Auto WPA Mode with AES Cipher and a pre-share key. This yields fantastic results with my laptop, it can stream video for entire episodes, and I have no problems with loading webpages in either IE or Firefox. However, it does not support the kids iTouches or N3DS.
2) Changed the above to mixed 802.11n/g AND ALSO tried 802.11 only: iTouches work and can connect to the internet, but laptop doesn't like it. I get "Problem loading webpage" every other time I access and website, and streaming stop every 5-6 minutes. Bars indicate wireless signal is strong, but intermittently get that yellow triangle.

I am having trouble connecting to my home computer from my work computer via the Windows Remote Desktop Connection app.On my home computer (win 7 pro) I have:
1. Allowed incoming remote desktop connections
2. Verified that the firewall is open for RDC
3. Forwarded port 3389 on my router to my devices static IP
4.Verified that I am using the correct IP (Router has a dynamic IP but I called home and had my wife read the current IP # from whatismyip.com)
5. Setup an account on the home computer that is password protected
I am connecting from a win XP pro computer.I receive 0% packet loss with reasonable time delay when pinging my home IP from the work computer.I also asked a family member to try from a different location (using Vista Ultimate) with the same result Error is that connection is never established and I am never prompted to logon to the home computer.I can connect via RDC when on the home network.

I've just had a custom computer built and I seem to have a problem with my wireless internet connection. I have a Realtek 8185 extensible 802.11b/g wireless adapter. My computer recognizes my house's network and is connected to the internet with a good connection, but when I open up my web browser it takes a very long time for the page to load and sometimes never does. The laptop I'm on right now is connected to the same internet and it is running just fine. I've uninstalled the device and rebooted to have the driver reinstalled but the problem still occurs.
