Wireless drops connection after 30 minutes

I just installed my first wireless (802.11b) network, and I have a
question. My wireless adapter (Win98 pc) connects fine when the pc is
first booted, but always drops connection after about 30 minutes. The
only way to re-establish connection is to actually reboot the pc, and
it then works fine for another 30 minutes or so. Besides interference,
what would cause this? I've tried a unique SSID, plus various
channels. I do not think it is interference, because the pc is only
about 80 feet from the router, I do not have any 2.4ghz phones, and I
figure if it was interference, why does rebooting fix it.

I appreciate any advice...

To be honest, eighty feet is pretty good going in my experience.
Indoors I get no signal at the front of my house, from my AP mounted
on the rear wall - thats about 50 feet through four brick walls. I get
about eighty feet outdoors - I can _just_ get a signal sitting at the
end of my garden. I'm afraid that the advertised range is best-case
line-of-sight perfect weather conditions, with all the aerials aligned
just right, and a following wind caused by lots of salesmen spotting a
mark.....

Important factors would be the design of your antenna in the PC
(external? Internal? can you change its orientation?), and the design
of the one in the AP (same stuff), the orientation of both (some
antennae are quite directional, try moving the AP around, standing it
on its end etc). If its an option you could fit an external antenna on
the AP, aimed at where you most need signal.

Shutdown power management in bios and software. Have a look at wake-on-lan
stuff etc. ect. on your NIC.

Good luck.

Thanks for all your advice. I did forget to mention that this is a USB
adapter (not a card). I don't know if that makes a difference as far
as troubleshooting. I also tried replacing the USB 1.1 port with a
2.0, but that didn't help. Could power management be turning off the
USB port? I'm at work now, so I'll check it out when I get home.
Thanks again!
