Hi all

I am trying to get Intel Wifi AX200 card working at 5GHz.
I have kernel 5.10.34 with linux-firmware-20210315 installed.
I even patched regulatory db as suggested here - https://vimeo.com/22938112.

Now

Code:

So not 5GHz AP mode is possible with hostapd:

Code:

interface=wlan0
driver=nl80211

hw_mode=a
channel=149

country_code=US
wmm_enabled=1
ieee80211d=0
ieee80211h=0
ieee80211n=1
ieee80211ac=1

It just emits:

Code:

# hostapd ./hostapd.5ghz4
wlan0: interface state UNINITIALIZED->COUNTRY_UPDATE
Frequency 5745 (primary) not allowed for AP mode, flags: 0x20053 NO-IR
Primary frequency not allowed
wlan0: IEEE 802.11 Configured channel (149) or frequency (5745) (secondary_channel=0) not found from the channel list of the current mode (2) IEEE 802.11a
wlan0: IEEE 802.11 Hardware does not support configured channel
Could not select hw_mode and channel. (-3)
wlan0: interface state COUNTRY_UPDATE->DISABLED
wlan0: AP-DISABLED
wlan0: Unable to setup interface.
wlan0: interface state DISABLED->DISABLED
wlan0: AP-DISABLED
wlan0: CTRL-EVENT-TERMINATING
hostapd_free_hapd_data: Interface wlan0 wasn't started
nl80211: deinit ifname=wlan0 disabled_11b_rates=0

Any help?

I tried for a while a year or so ago and had no real success even though the adapter claims it is possible. Then there is this: https://www.intel.com/content/www/us/en/support/articles/000030429/wireless/intel-wireless-gigabit-products.html I wish you luck and hope you can create a wiki

I believe that AX200 does not support 5Ghz band. I guess I need to move to another hardware instead.

I am allowed 4 channels but from memory it still would not initiate as an AP , I forced several times and with iwmvm and the other module iwldm? , that just caused segfaults. Once again if you do have success you will be very popular for a wiki.

running similar to you :

Code:

iwlwifi 0000:03:00.0: Detected Intel(R) Wi-Fi 6 AX200 160MHz, REV=0x340

good luck
