Sorry to post this like this but I figured no one would look at an old post. Thanks. http://www.computing.net/networking/wwwboard/forum/18697.html

And the results were the same after you followed Steve's excellent advice? You migth try this; when both machines are access the internet do a ipconfig and not the stations ip address and dns listing. Ping for example microsoft.com and see that you get ping back. When it goes dead so the ping and ipconfig. What are the results? Go into the routers log file and see what its says. Perhaps it will give some clues like isp link down for example would tell you something is going on with the isps connection.

that was a "e' on the end of not so note the dns and ip address. When the internet goes down can you ping between the workstations? If so this would indicate that the router as far as the lan side is working fine. That's half the equation.

Hey guys- I'm having a very similar problem with my new linksys router dropping my internet connection and I think I finally found a solution! Here's the background info: Got a new PC last week and I wanted to create a home network with the new PC (Win XP Pro) and old Win 98SE PC so they both can use the internet. Here's my Config: ISP is Adelphia Location is Northeastern PA. Ericsson PipeRider cable modem New Linksys router BEFSR41 V3 (wired) firmware: V3 version 1.04.8, July 20 2003 New PC is generic built by local store with 2.8gig P4 CPU/512Meg ram/Intel D865PERLK motherboard with built in Intel Pro100 LAN port - New PC running Win XP Pro and Norton Internet Security (Norton antivirus, firewall, spam block, privacy thing, etc). Old PC is generic AMD450 CPU/128meg RAM/Kingston 10/100 eithernet card running Win 98SE and ZoneAlarm. Old Win98 PC works fine surfing the net with the linksys connected. However, when I surf the net on the WinXP PC, it always connects ok at first, but then the WinXP PC randomly drops the internet connection! Sometimes the WinXP system is connected for 2 minutes, sometimes 30 minutes, but it always drops. When this happens, I can ping the router OK from both PCs, but I cannot ping the modem, so it appears the router is loosing connectivity to the modem. Strange thing is, the modem and router lights are still flickering and I cannot ping the modem! The only way to restore the connection is turn router off/on or hit reset on the router. I did notice that the WinXP PC is more likely to drop when I am doing lots of activity (ie several MS explorer windows open). WinXP will stay connected for hours if there is no activity. This problem has been driving me nuts for almost a week, but I think I fixed it last night. I tried the following on the WinXP PC: 1) Disable WinXP firewall - did not work, still drops me. 2) Disable Norton Internet Security (firewall, not anti-virus). Doing this scared me since I now felt wide open to the net, but I hope the router would block anything nasty. However, this did not fix the problem either! 3) And finally, last change was the charm - I was going to update the router firmware and read on linksys site that you must switch to static IP and change the network connection to 10mbps prior to doing the firmware upgrade. Not sure why, but linksys said to do it, so I changed WinXP from get IP address dynamically to static assigned -ip=192.168.1.2, subnet mask=255.255.255.0, default gateway=192.168.1.1 and then I plugged in my DNS numbers for Adelphia. Then I changed my LAN connection to 10mbps and rebooted. Tried it before flashing the firmware, and it worked great!! Stayed on for a few hours last night! I never did flash the firmware, but I may do that later as well. Sorry this is soooo long, but I hope it helps you or anyone else that is pulling their hair out trying to get the linksys stable. Anyone have any comments as to why this worked? Good luck, John O.
