Hi,
Is it possible to check for whether the N-mode is alive on the laptop and not
blocked by the OEM (HP)?
I don't have access to an N-mode AP to try to associate and check; but I'm
planning to buy a new AP/router - so, might as well go for one having N-mode
now that it's standardised.
The device I have is AR9285 - which does have N mode support as per the
following iwconfig output:
kunal@plutonium:~$ iwconfig wlan0
