[Voyage-linux] Re: Low bit rate on hostapd AP (802.11n)

[Przemysław Matejko]

Problem solved, that was my mistake (wrong backup of config file).  I
had 150Mb/s on previous system, but when wpa_pairwise was set to TKIP
- on Voyage I had CCMP (which is stronger algorithm), which causes
lower rate.
It seems I have to choose beetween speed and security...
