while browsing the web, once every 15-20 mins or so I won't be able to connect to any web sites for about 60 seconds. I get the Firefox error "The connection to the server was reset while the page was loading", and I will need to click "try again" or refresh several times before any pages will load again.

The interesting part- while this is happening, I can still ping yahoo.com, google.com just fine, and games that are already connected to the internet aren't interrupted.

I'm running windows 7, connecting to my wireless router using a WG111v3 USB card, and using WPA2 with a strong passphrase.

Any ideas? Thanks in advance!!

The connection to the server was reset

I'm fairly certain this is indicating that the remote server closed the connection with an RST, this is very different from something timing out.

Are you on an ISP that does traffic shaping? Do you have one of those shitty anti-virus/firewall apps?

maybe try running some of the tests at http://www.measurementlab.net/measurement-lab-tools

The best thing you can do is install wireshark and get a packet capture of this in action.

If some device on the internet is sending you RST packets, then that rules out almost anything you can fix on your machine.

Open the advanced WLAN adapter properties, set the Power Saving mode to OFF/CAM (constantly awake mode) and see if the problem persists.

Edit: test the connection with an unencrypted network or change the channel of the router (maybe another appliance or wireless network nearby is causing an interference).

thanks, but did not resolve the issue –  jeff Jan 2 '10 at 18:57

From your description of symptoms, I suspect a problem in Firefox, likely with an extension. You might start by using Internet Explorer on a few web sites for a half-hour to an hour. If no intermittent problems are noticed, then run Firefox in "safe mode" without any of your extensions enabled, for a half-hour to an hour. Again, if you don't notice any problems, it points to a Firefox extension.

Now run Firefox with extensions enabled and disable as many of your newest extensions as you can remember, or disable all of them to be safe. Then enable them one-by-one until the problem returns. Disable that extension and continue enabling the other extensions one-by-one. If you don't see the problem again, it is likely an interaction between that one extension you still have disabled and another extension that you enabled before the misbehaving one. Send a note to the extension author with a list of those active extensions and see if the author knows of a conflict or can discover a conflict with another extension.
