Ok. I got a chance to try it.

Try changing the line that says PAN_ROLE=GN to PAN_ROLE=NAP (line 23 or so).

Apparently the Blackjack only acts as a network access point and not a GN controller.

I also modified my script to use dhcp per fanoush's earlier post.

It seems to work quite well. I think I'll use this method instead of the hack I'm using now.
