I see two things here, one is that there is no IP on that wlan2, indicating that 
it is connected but not routed. The other is that it's wlan2 insteadl of wlan0, 
indicating that something is going on, since even with the built-in (802.11g) 
and plug-in (802.11n) NICs, I have wlan0 and wlan1, so they always do start and 
zero and go consecutively.

Try:
- dhclient wlan2
- netstat -r
and post the results. I would expect you will get connections after that.
Your dmesg output should have information of why that's wlan2, please read and 
report.
