Ahoj,
rad bych se zeptal, zda se nekomu uspesne podarilo nakonfigurovat
FreeBSD
jako access point na 802.11n.
Pohravam si s Alixem (prosim, pominme vykonnost ALIXu pro 802.11n) a
miniPCI kartou
Compex WLM200NX (AR9220)a v rezimu 11n ne a ne docilit stabilni
konfigurace.
V rezimu 802.11g bezi AP jako vino.
Zde je me prostredi (config pro 11g):

Veskera doporucena nastaveni z googlu vetsinou konci:
ath0: stuck beacon; resetting (bmiss count 4)
nebo poklesem rychlosti na par kilobitu.
Diky,
zdravi
