Sorry for the "me too" post. but i've had the same problems with 2 Linksys routers. I exchanged the first one, thinking the problem was with the router, but the second router has the same problems. There are 3 computers on the network, 2 running OS X, one running OS 9, and they all drop connection with the router on at least a daily basis. Looks like its time to switch companies. It only seems to happen with the wireless routers however. When i had just a standard 5 port Linksys router, we never had any problems.

Just to update all you friendly folk that tried to help me: after trying everything and anything I took one last suggestion and exchanged the router with linksys. The new one is working fine. Thanks for your help.:)

firmware?
 

Have you tried to find a firmware update for the router? I had a similar problem with 2 netgear boxes which were fixed instantly with a new firmware update. A simplistic answer but sometimes they work the best.

Thanks. Firmware updating was one of the many, many suggestions that I tried. But to no avail. Since I exchanged routers with linksys, however, I no longer lose my internet connection, either on the wireless or wired computers.

good stuff
 

glad to hear all is well...
