<html><head></head><body>OK it is a broadcom chipset which is supported using the b43 driver which is in kernel on most modern distro's for at least the last 2 years.<br>
<br>
I'd suggest doing a 'modprobe -r b43' and then a 'modprobe b43' and then check the kernel logs to see what is going on at the driver level. This should indicate what is going on with the wireless card and driver layer.<br>
