This is interesting to me too but the reverse problem. My Vista 64 bit
connects to the Internet wirelessly every time, even if I am physically
connected to the Ethernet. I am familiar with wireless device options that
permit user to disable the wireless connection in the presence of an Ehternet
connection, but I am not finding that here. What I want is default connection
to the Ethernet LAN if the cable is connected, and default connection to the
wireless if the Ethernet cable is not connec ted or there is some other
problem with the LAN. Both the LAN and the wireless are connecting to a cable
modem via a Linksys router. The connectiosn and the preference I want works
fine for other computers on the network - it is only this one with the Vista
64 bit that has this problem.
