Bjoern,

I've attached the logs here.

The funny thing is, after I set the country to what the router says, it 
did connect, but ifconfig still says it's 802.11a. However, the speed 
greatly improved: it now shows 90+ Mbps instead of the 10 I saw before.

So probably, I don't have the problem I've originally reported.

Still, ac doesn't seem to be on, tho.
