I`ve not found this problem with any of the USB wireless adapters I`ve tried. How are you connecting them? Are they in the main USB ports or thru a hub? Is your ASDL modem also USB? As you state the problem occurs on the first pc when you try to connect to the internet I would look at device conflicts or power problems via USB first. On the second machine at what point in the install does it freeze? I would try removing the drivers and reinstalling, both with and without the adapter plugged in, yes I know what the manual says but it can make a difference. Get the latest driver from the Belkin site just in case but I am sure this can be resolved, the first wireless adapters I set up took me a while to suss out but I got there in the end!
