Netgear WGR614 Intermittent Disconnectivity Problem

Hey all.

Have what seems like the archtypical wireless router problem - often the wireless signal stays strong but the connection to the internet doesn't go through. This is always fixed by restarting the router - unplug and plug back in. Very annoying.

1) What is going on here. I don't care to do this, but come on, there has to be a permanent fix.
2) What is that fix.

All connected computers generally run Win XP Home, if it matters.

Thanks,
Steve
