I've installed the 1.40 driver for this wireless card on my AMD3000+ computer running Windows XP home edition with SP2.
The system has a built in network card and currently connected to a DIR655 through a network cable.
When I add the DWA552 with the current driver or the older version 1.30 it lock up my network. I have to disable the wireless card to get the network rolling again or vice versa.
I have a laptop that when I connect to the router through wireless G and wire at the same time it seems fine.
