Cannot connect to LAN in evenings, but WiFi works fine

I've been with Uverse for 3 months now.  I've had a few problems but nothing major.  However, for the past week my desktop starts losing it connection to the network starting in the afternoon, until around 9-10pm, it cannot connect to anything at all.  The weird thing is that my laptop can connect to the WiFi, no problem.  I've tried restarting the router, and unplugging/replugging it; still no internet!

 

Has anyone had this experience?

What OS are you running and have you got it connected by ethernet or is it wireless also.

Vista, wired ethernet.

 

As I said, the wired ethernet works in the morning, then when I get home from work, it will have started to lose connection 'til it is completely gone.  The laptop I have, however, continues to connect with WiFi with no problems.

By "morning" do you mean when the desktop is first turned on for the day? If so, the problem could be heat related.

It could be a NIC card going bad . If you run connection manager does it specify anything also try a different port on the router.

It could be a trojan / virus / root kit and someone is using your computer - have you done a comprehensive malware scan lately?

 

Does that box have any special applications? Or an online backup program (and maybe you got the clock times reversed or put in 9:00 instead of 21:00 ...)?

 

If you do a ctrl-alt-delete and bring up the task manager, you can see applications that are running, and processes - the processes list also shows utilization ... you should be able to locate the application(s) or processes that are killing your throughput. There is also a window that shows network throughput, if some other application or process is hijacking your bandwidth, it should show up on that screen as 100% (or near) utilization.

Figured it out.  The wired ethernet goes through the electrical system of the house through those cool plug in adapters.  I had the one on the computer side plugged into a surger protector.  I moved it to the wall socket and it works great.

Those adapters are pretty nice, aren't they?  :smileyhappy:
