Hi Eddie,

Ok, thanks.

That looks correct.

That also looks fine.

Ok, that shouldn't change anything in this case, but good to know.

Yeah, I forgot to ask about the AP. Can you show the output of "iw wlan0
scan dump" for your AP while you're connected? It should show something
like this (note the "associated" indication):

BSS 02:00:00:00:00:00 (on wlan1) -- associated
	TSF: 1352188517669470 usec (15650d, 07:55:17)
	freq: 2432
	[...]

I'm particularly interested in the "freq" (as above) and the HT
capabilities/operation information.
