Huh? TL-WN721N should be ar9271 hardware. All ar9271 devices are
single stream devices which means the highest MCS rate is MCS 7. I
forget but I believe 11n wifi cert accepts single stream devices now.

As per Christian it seems this is an ar9170 device, which is dual
stream and using the older Atheros hardware. It certainly has capacity
to TX/RX more but remember that it is more expensive too. Single
stream devices bring 802.11n hardware price down to a competitive
level and kill 802.11g :)
