Can you please try this firmware:

I have verified that it works fine for me when connecting to an
AP on a DFS channel.  It should have the bridging fix as well.

There was an inverted beacon-filter setting bug in my code, though that
also should have been fixed in the previous firmware I sent you.

I might have had some other problem in that older firmware, however.
