When I first bring my Dell 520 up, the network card connects and disconnects randomly for about 5 minutes. I've updated to the latest drivers, turned off all power management (except standard sleep), and I still have this problem (the tech support folks said to turn off hibernate to solve this, but turning it off did not solve the problem). Any ideas on what the problem is? Does anyone else have this problem? This really waste about a half an hour a day while I wait on this card to crank up and decide to start working. Russ
