Any ideas how I can troubleshoot this?
OK, I found what the problem was ... the AP is currently transmitting on channel 13, which it seems is outside the capabilities of the b43 driver. I am blaming the driver here because the Windows 7 OS has no problem using channel 13, while iwlist wlan0 in Gentoo shows only up to channel 11. :-( Will need to wait for the driver to hopefully improve. -- Regards, Mick
