wow, that's old. Luis posted a "special" compat-wireless release
for carl9170:

"See Announcement: Re: Compat-wireless release for 2010-10-01 v2 with RX filter for carl9170 on -p release"

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Now that's interesting, apparently Netgear's AP can't send HT (802.11n) frames!

But that's not your problem, it's the missing WMM extension.

Your AP should (additionally) display:
        WMM:     * Parameter version 1
                 * BE: CW 15-1023, AIFSN 3
                 * BK: CW 15-1023, AIFSN 7
                 * VI: CW 7-15, AIFSN 2, TXOP 3008 usec
                 * VO: CW 3-7, AIFSN 2, TXOP 1504 usec


But since it doesn't, mac80211 does not enable ht.

Maybe a new firmware for the router would fix the issue?
