Good. I have a bunch of these around as well. Which firmware version ?
It should say so in small print in the upper right corner of the Web
GUI.

Did you check dmesg whether the association was still there ? One
thing that could cause such troubles is DHCP trying to renew the
lease and something going wrong there.

One way to find out would be to run

iwconfig eth0
ifconfig eth0
route -n

while the connection is good, record the output, and run these
commands again after the connection has failed. Then post them
here for analysis :-) Including a dmesg output wouldn't hurt
either.

Thanks,
