last week, me and my friend where playing with are laptops.
We connected to a wireless network that was BG and my wifi card is B/G.
First I was connected then when I try to connect again, windows tells me
that my card does not support it when I was just connected to it.
My friends wifi card is also B/G.
please help.
P.S. I got Vista Home Premium

Hi
May be there was a change in the Wireless' source parameters (like security
was added).
Otherwise, to check your own system, the following might help.

P.S. the card is built-in and I use it a lot.
