Windows 7 intermittently drops wired connection

I have same problem, network randomly drops every so often while using the computer.

No wireless, all wire. Doesn't happen on any other of our systems running 7.

Okay guys stop bumping this thread. If you too have a problem create your own thread so that everyone has a chance to read it.
Also I should like to point out that you need to
1st check that your router is not overheating they don't have to get very warm before they break down. At room temp they only need to be on the carpet to overheat...
2nd Reboot the router and check all settings.
3rd Still a problem it's more than likely the router in this case.
All the best

This has absolutely nothing to do with a router. Nothing at all. Nada, zip, zero. It's also not a thermal issue. Perhaps you could have read the posts before you quashed the thread.
Let me reiterate that it's local to the machine and has nothing to do with anything beyond the physical computer case. Okay?!
I tried reinstalling with new Realtek drivers - it didn't work. In the process I also lost my sound 1/2 hour before the Super Bowl! Luckily I was able to figure out that it reset my audio drivers and had put the audio output to speakers instead of HDMI... 5 minutes before kickoff! *phew* Still at square 1 with this problem. >

I have a theory about all the network connection issues

what I think may be happening here is when an update of the device driver occurs during the time when the adapter is actively connected something happens to then cause the connection issue.

I would download the latest driver from vendor save it and disconnect the active connection if it's wired LAN unplug LAN cable if it's wireless turn off radio switch uninstall the device from device manager along with any other software connected with the device apply new driver and reactivate adapters and reconnect

lol

I've also got a problem like this on a slightly different setup.

I've got an Internet connection from my ADSL2+ modem to a Windows 7 PC. I can use the Internet fine on that PC alone. However when a networked PC (they're Windows 7 and XP based) start trying to use the Internet dropouts start occurring; sometimes it'll drop out in 1 minute and at other times it'll work for an hour or so before carking it. The thing is even though the Internet drops out the actual network still works so files can be shared and copied over.

By the way the modem is also connected to a Realtek network card port, probably a trend with this brand?

I've been thinking of buying a switch to see if it'd fix it but I'll see how it goes here first.

I'm going to be buying a NIC this week and hopefully that will fix the problem. I do believe that this is a Realtek/Windows 7 issue that they have failed to address. Here is the statement from a Windows 7 employee on their forums (scroll to bottom, post by Cody): Windows 7 and loss of Internet connection

Before you go and buy a new router or whatever, I've found that this solution helps a lot of people that have the same complaint.

I'd like to suggest taking a look at your Network adapter. Start -> dev manager -> network adapter. Double click, open her up and then under "advanced", take a look at "Link Speed & Duplex".

If this is set to auto-negotiation, try re-setting it to 10 or 100mbps Full Duplex, re-start your computer and see if the problem persists.

For whatever reason, auto-negotiation features in some network cards poor.

Didn't work. Still same problems, going to go ahead with buying the new NIC tomorrow.
