Don't worry Kevin - "There's something wrong with bgscan" with 802.11n.

Even with pre-11n stuff, the code for scanning resets the NIC very
often (one per channel change) and this occasionally results in some
weird behaviour.

Further investigations are on my TODO list because of how sensitive
this is with 11n.
