Hi, I've been using the WRT54G for a while now and for some reason it started to act up on me and I'm not sure what's wrong. Here's the problem: The router would be working fine, but then after like 12 hours or so all of the computer in my network starts losing the ability to web browse. Programs like MSN messenger and Yahoo messenger still works but web browsing doesn't. I try to Ping the router and it doesn't reply. If I hit the reset button on the router it works again, but only for like 2-3 hours before the problem shows up again. If I turn the router off for about 15 minutes and then turn it back on it works for another 12 hours before the same problem shows up. I have 2 CAT 5 and 2 CAT 5e cables hooked up to it. I have WEP on and it takes 4 Keys to log into the wireless network. I change the password of WEP and the router every month. The router has the lastest firmware released by linksys on it. And the router is kept well within the approved environment for operation. Could anyone please tell me what the problem is so I can search for a solution. Or if you know the solution please tell me. Thank you for your time.
