One of my computers is running Win98 SE and has a 3Com NIC in it. It works great, connects to the net, everything... for a while. After about 2-3 hours of being connected to my network here, it drops the connection. The only way to get it back is to restart.

I haven't tested the ethernet connection yet, but I have tried updating the driver for the NIC.

I just don't understand what would be causing something like this!?

Any ideas?
