Koszi!

Es azt hiszem talatam egy nagy bugot: 5GHz-en nem lehet AC-t bekapcsolni (VHT80) !!!

VHT: 40-el elindul a dolog, s mukodik is (az az N-es szabvany lenne 5GHz-en?), de 80-al meg sem mozdul (minden mas ugyanaz a configban, shh-rol javitva a konfigot, s onnan ujrainditva a networkot.)
Es ezt mar a reghack elott is csinalta.

A helyes konfig (ami most is fut) :
config wifi-device 'radio0'
option type 'mac80211'
option hwmode '11a'
option path 'pci0000:01/0000:01:00.0'
option noscan '1'
option country '00'
option channel '44'
option txpower '23'
option htmode 'VHT40'

config wifi-iface
option device 'radio0'
option network 'lan'
option mode 'ap'
option hidden '1'
option ssid 'xxx50'
option key 'xxxx'
option encryption 'psk2+ccmp'

Amivel nem indul el (csak a HTmode van valtoztatva):

option htmode 'VHT80'

Ekkor az iwinfo ezt adja:
root@TpLinkArcher:~# iwinfo
wlan0 ESSID: unknown
Access Point: 00:00:00:00:00:00

Amikor jol mukodik, akkor ilyen:
wlan0 ESSID: "xxx50"
Access Point: E8:DE:27:59:AF:C0
Mode: Master Channel: 44 (5.220 GHz)
Tx-Power: 23 dBm Link Quality: unknown/70

Es mikor a luciban 80-as van kivalasztva (mikor nem indul el), akkor save/apply utan a fo kepernyojen a Mode-nel Client van !!!! (es nem AP , ugyan a konfigban 'ap' szerepel.) Tehat az a resz is bugos.
