I have a wireless network with Linksys cable modem and router. On the wired computer I can use firefox (2.0.0.4) for a while but the internet connection eventually stops working. I must then restart the computer and the process starts over. I am able to use Internet Explorer and it never crashes. I have no problems using anything on the wireless laptop and it stays up even when the connection on the wired computer ends. I took the router out of the network to test and firefox eventually crashed again. Hmmm. Suggestions?
