I modified the source to force the tx power up, and signal level stays high, and the rate does not drop below 54Mb/s, but... throughput still remains low, and after rx of around 400-500kb of data I get a kernel panic, entire system locked up, just capslock flashing.
Any suggestions on how to catch the oops details, I reboot but they have not appeared in the logs, it must be crashing so hard that the kernel does not get a chance to write them out.
