$ iwlist scanning
doesn't return any network on pair channels. And I can't associate with network on pair channels.
I thought it could be faulty hardware, because experienced same odd behaviour using Cacko1.23 on my c760 (only tried channel 2 though), but then I tried wellenreiter, and it began detecting my network on channel 2, and other vicinity networks on pair channels.
Is the card faulty? Or just the driver? Any of you experienced something similar?
