Greetings,
I thought I'd do some testing with a recently acquired AR9220 MiniPCI
card (a Compex WLM200NX) in AP mode. It seemed to be fine for an SSH
session but locked up as soon as I tried some bigger transfers. I'm not
sure what I should be prodding to get further details -- nothing
relevant turned up in dmesg.
At bootup:
