Ah. Where to begin?
I have a 5 computer network--2 wired, 3 wireless--a Belkin Wirelss G Router F5D7230-4 version 5000. Various computers, wired and wireless, lose connection with the Belkin router at various times and sometimes all of them at the same time. Sometimes there's just a loss of internet, but usually it's a loss of intranet. Sometimes the router utility shows the computers as connected, but the individual computers involved in the incident show they are not connected even though they can detect the network and the wireless have good connections.
Things I have tried: contacting Belkin. Their advice was to reset the router. That didn't work. There doesn't seem to be any firmware available for download, but then the Belkin site doesn't have version 5000 listed (made especially for Wal-Mart?

). I've disabled security. Didn't help. I bought a 900 MHz phone to use instead of the 2.4 GHz. Didn't help. I've set static IPs. Didn't help.
I had similar problems with the Netgear I used to have. The only temporary things that help are sometimes to have the problem computer(s) log off and log on again (sometimes works if the Belkin router still thinks the computer is still connected). Having the problem computer restart sometimes fixes the problem. If I can still connect with the router from my wired computer and can access the router utility, I can have the router restart, which temporarily fixes the problem. When all else fails, I unplug the power cord and plug it back in. These are only temporary fixes. Sometimes the connections fail several times a day, which is really frustrating because the 3 wireless computers are homeschoolers being disconnected from their school work.
Is this a common wireless router issue? Is it fixable? It's bad enough that I have teenager volunteering to crawl under the house to run wire.
