[SOLVED] "no IR" on almost all 5Ghz ac channels #586

Open lukasz-bielinski opened 4 years ago

lukasz-bielinski commented 4 years ago

hi,

i am using tp link usb card t9uh ver 2.0 with drivers aircrack-ng/rtl8812au branch v5.6.4.2.

problem is that almost all 5GHZ ac channels cannot act as ac access point

        Frequencies:
            * 5180 MHz [36] (20.0 dBm) (no IR)
            * 5200 MHz [40] (20.0 dBm) (no IR)

i saw pr https://github.com/aircrack-ng/rtl8812au/pull/531, this code is present in my drivers but mentioned channels are not available for access point.

please advise what i can do to enable more channels.

edit: usb card is connected to raspbery pi4 with latest raspbian

i cannot start access point on channel with 80Mhz width.

is my config invalid?

with hostapd config below i have link 300Mbps. what should be changed to get link 860/1300Mbps?
