That's probably a different issue. Upgrading firmware won't solve the problem.

I'm guessing this is regulatory (wireless-regdb) problem. You can
verify that if you run `iw reg get` command. I get:

 country US: DFS-FCC
         (2402 - 2472 @ 40), (N/A, 30), (N/A)
         (5170 - 5250 @ 80), (N/A, 17), (N/A)
         (5250 - 5330 @ 80), (N/A, 23), (0 ms), DFS
         (5735 - 5835 @ 80), (N/A, 30), (N/A)
         (57240 - 63720 @ 2160), (N/A, 40), (N/A)

Note the @ 80 at 5GHz band which means it's possible to operate on
80MHz channel bandwidth. If you get @ 40 it means you have an old
wireless regulatory database. You can get the latest one here:
http://drvbp1.linux-foundation.org/~mcgrof/rel-html/wireless-regdb/ .
Make sure you have crda binary installed and up to date as well (
http://wireless.kernel.org/en/developers/Regulatory/CRDA ).

Support for firmware-2.bin was added in kernel 3.13.
