I have an HP p6733w-b desktop with AMD Phenom II 511, 3.4 ghz dual core, 5 gb DDR3, Windows 7 Home Premium with all updates and Internet Explorer 8. I have Norton Internet Security 2012, Super Antispyware, and Malwarebytes. My internet is AT&T DSL. My router is A Belkin N+. My main computer is hard wired to the router but I also have ANOTHER computer ethernet hard wired to it and at least 2 more COMPUTERS, a WII, and other devices that connect wirelessly. The internet or network disconnects most of the time on the main computer when I leave the computer idle for a while. When I try to reconnect or troubleshoot, I am told that no connections are available. All of the other computers, WII, Internet DVD players, etc. are not affected and maintain their internet connectivity. The only way to reconnect is for me to reboot. When I reboot, it takes a long time for the computer to shut down. I am considering wiping the hard drive and completely starting over, but wanted to ask you guys if you have any suggestions that I could try; i.e., reinstalling Internet Explorer, reinstalling networks or something? I do not lose connection as long as I am actively on the internet, only when the computer is idle. All my devices have been unplugged and rebooted several times since this started but that doesn't resolve anything. Try these in order.

1. Try a different port on the router, swap the main PC with another computer's port.
2. Reinstall your network card drivers.
3. Restart the router.
4. RESET the router.

If none of these work, I can offer more..I haven't abandoned my question. I am testing the things you recommended to see if my computer continues to lose connection. It takes time, so I'll return when I've tried them all. Thanks.Good evening

This sounds and awfully lot like a IP conflict, or a HOT router or a miss-configured router.

You can also try this shut down ONE of the desktops that is having the issue and unplug the cat cable and reboot the PC if it boots normally and shuts down normally it is in your router more than likely or you have a bad cat cable etc.

Hope this helps. Quote from: hartbeatmr on July 20, 2012, 03:47:57 PM
