thanks again ! ok, it must have popped up by coincidence at the same time I was installing the drivers.
Here's my 802.11 status:
I have been getting the Windows updates. Everything seems good on the machine (except for the motor revs up and down - I'll post that separately).
I clicked on driver and "Update Driver" and it said "Windows successfully updated driver . . .". Now I'm at 4.0.10.0 for 802.11 b/g.
