Your adapter can not transmit to channel 36, frequency band 5GHz.

Hi! I found this tool while looking for a solution to create an access point with my AX200 PCIe card. I'm looking to connect my Quest 2 VR headset (which supports WiFi 6) directly to my computer with as little latency as possible, and no access to the external internet. My understanding is that a 5GHz hotspot should provide this, so I ran the following command:

$ sudo lnxrouter -n --ap wlan0 MyAccessPoint -p passphrase --freq-band 5
linux-router 0.6.6 (https://github.com/garywill/linux-router)

I had the same issue trying to use linux-wifi-hotspot, so I think it's an issue with create_ap, but it seems it is now unmaintained. Is there anything I can try? The 2.4GHz hotspot gives me 58Mbps, which is not what the AX200 card I bought advertises.

I've attached the output of a few other commands:

Hey, I have the exact same issue. I've got it working by using nm-connection-editor to create a new 5ghz hotspot and then launching it with nmcli connection up hotspot

Thank you! I have since bought a dedicated router, so I do not need to create a hotspot anymore, but at least this solves it for people who come across this issue.

@HuggieBo Hi , I am facing similar issues, can you detail about ho you setup 5ghz hotspot using nm-connection-editor
