Linksys Router Disconnects Both Computers

This is my first time using this site in a very long time. I'm not sure if I'm posting in the right section. Please feel free to correct me.

I have DSL service and I've been using a linksys WRT54GS to service one computer that runs XP for 4 years now. I've had no trouble out of the router. Now, when I built this new computer that runs Windows 7, I have both computers hooked up to the same router. They WILL work together, but they don't always. Periodically, usually only once per day, both computers will lose connection to the internet at the same time. The internet lights on the DSL modem are still blinking, but the little icon at the bottom of the screen says no internet connection. The router can still be accessed during this time by typing 192.168.1.1 in the address bar of internet explorer, and appears to still be receiving an ISP from the modem, but it just isn't routing. The most typical time I can recreate this error is by running SWTOR (resource hog of a video game) on the Windows 7 machine, and then turn the other computer (Windows XP) on. As soon as the power button is pressed, before it even tries to load windows (not sure if it's before POST), the internet dies on the Windows 7 machine. Then, after the XP machine is booted, it has no internet either. I have to power cycle the linksys, and the DSL modem and all is fixed for the rest of the day. I've looked up what could be causing this several times, and have yet to find anything that fixes it. It's also sort of hard to test, because it doesn't always do it. I bought a new Linksys Dual band E2500 and the same thing happens with the same frequency of occurences.

One of the suggestions I read on another site is to disable uPnP on the router. I've done that, but it still happens. There is only one phone cord coming into the house, and it is running straight to the DSL modem, and there is no filter on it.

Thanks for reading. Any suggestions appreciated. I hope the format is correct, as I've not posted a question here in more than 5 years, probably.

oops! I just noticed there is a networking subforum, and this probably should go there. I swear I looked several times for one. Any way I can move this over there?

Sorry.

Hello GotSnazz,

I'd like you to try something and post back with your findings.

When the computer looses it's internet connection, open up a command prompt and type the following command; ping 8.8.8.8

Does the ping work? Or does it come back with a timeout?

Regards,
Olrik

Thanks for the reply. I'm having trouble getting it to foul up on command... Go figure. I get the impression that when both computers are turned on, initially, it has a chance to either work, or foul up, and if it works, it does so for the remainder of the ip lease from the ISP. If it fouls up, it sometimes takes 2 or 3 more attempts to get it right, and then once it goes, it's fine. In other words, I think if I take a break from trying for a few hours, and force the ISP to send me a new lease, it may screw up again so I can post back with the results you're asking for.

i reset the dsl modem and linksys router, and it didn't restore the connection. tried once more and it didn't work either.. then after about 30 seconds, it worked all of a sudden.

Sounds like packet loss/your line goes down every so often.
I had this very same problem and contacted my ISP who realised a problem their side
I would speak to your ISP and let me know how many times the connection is dropping and times and dates this is occuring
