Given that more than one PC is affected and that you are getting some very
bizarre symptoms, I'd suspect two things: 1) interference from another
router on the same channel; 2) the router has died.

Download NetStumbler (www.netstumbler.com) and install it on one of the
wireless PCs. With your router turned off, run Netstumbler and see what
other networks are visible and what channels they are using. Now turn your
router on and re-run Netstumbler. You should see your own network as well
now.

If there is any other network on the same channel as yours, try configuring
your router (by an Ethernet connection from the PC) to use a different,
unused channel, preferably differing from any neighbouring network by at
least two channel numbers. I think channels 1, 6 and 11 are non-overlapping;
any others overlap to some extent with these. With the WAG54G, I think you
have to explicitly save any config changes and then reboot: alway check
after rebooting that the change has "taken" and that you haven't reverted to
the previous state.


If that doesn't solve the problem, I'd suspect the wireless access point in
the router. I've seen quite a few Linksys routers fail one way or another -
far more than Netgears, and Netgears are far more common with my customers.
