"The chip fully supports 802.11n"
This is Draft-N specification, not Final-N.
http://en.wikipedia.org/wiki/IEEE_802.11n-2009#Wi-Fi_Alliance
In short, manufacturers have rushed to release WiFi 802.11n devices
before the specification was finalized - and, as result, compatibility
between Draft-N and Final-N wireless devices is not ideal.
There are lots of Final-N WiFi USB adapters, which could also achieve 300Mbps
- 450 Mbps
I am not interested in 802.11ac devices, because there is the same story (all
current 802.11ac devices are Draft-AC, final specification is not ready)
