I have already taken this problem to the Linksys tech support with no avail. Maybe, I can find a solution here. I have a Linksys WRT54G router using Verizon Online DSL. My problem is that my internet will slow down and eventually stop working and usually the solution to it is for me to unplug, wait 30 sec and plug my router back in. However, this provides only a temporary solution as hours later the problem will arise again. Basically, websites and everything will work fine, then hours later websites will take forever to load or not load at all. Some internet applications already online will work like AIM or Warcraft III. However, if i disconnect them they do not connect. I usually have 3 computer connected to my router which will run normally for a while then eventually bottleneck. I tried each individually with the internet and I have no problems of lag or such. The people at Linksys have already had me lower my MTU over and over again till it got to 1250 but that didn't work. They had me make a clone of my MAC address and that didn't work. I'm tired of constantly having to unplug my router in order to refresh the connection. I also tried to upgrade the firmware from v4.0 to 4.30 but all that did was make the application, NetSet(which usually auto sets up the router for internet), not work. I am really frustrated with this problem as all my previous attempts at fixing it have failed. Can someone help me?
