Hello, Adrian.

 Without reboot (iface dow/up) it showed very low speed (~30Mbit UDP)
 with clear environment (RSSI 28, RATE 270M according to list sta).
 After router reboot it is 140-160Mbit/s UDP (2x2 MIMO, HT40 channel),
 but with drops to 20-50M for 1-2 seconds.

 But I cannot repeat previous hang in this "clean" conditions :)

 It looks like I need wait night :)
