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:

interesting, why is MCS range just 0-7, which means no HT?

I have no clue why it's that way - I don't even know what HT means in wireless
context :)
Sorry, I'm just an end-user in this respect ..

MCS 1-7 is for single stream devices.

So, does this mean that I can use N-mode on this device?
That would be really great, if possible :)

Yes, MCS 7 is your highest rate on your card.
