I'm hoping to set up a 5Ghz hotspot from my laptop with wifi card: MEDIATEK Corp. MT7922 802.11ax with decent speeds. I'm connecting the hotspot to a Quest 3.
If I set up a hotspot from Windows, I can make it 5Ghz and my Quest says the link speed is 866mbps.
At first I was unable to set up 5Ghz using NetworkManager and Gnome, but was able to fix that by both editing the hotspot connection in nm-connection-editor and running sudo iw reg set GB
However after connecting, while my Quest reports the network is 5Ghz, it says the link speed is only 192mbps.
I decided to try creating a file in /etc/NetworkManger/conf.d/wifi_backend.conf with the contents
[device]
wifi.backend=iwdand restarted NetworkManager.
I then checked nm-connection-editor and there was a new second entry for Hotspot, I set it to channel a.
On creating a hotspot, for some reason it was still only using 2.4Ghz. Interestingly the link speed was reported on the Quest as 300mbps.
I also did some experimenting with hostapd, but after working through the configuration and setting up a hotspot, the link speed was even slower. Around 180.
What can I do to make the fastest hotspot using my card? It would be great if I could match the hotspot speeds I was receiving with Windows.
Edit: I tried some different channels as well, but if I try to use any channel above 48 the hotspot creation fails and I still only get 192mbps on 48.
Thanks.

Some more discoveries.
According to iw phy phy0 info | grep Frequencies -A 24 my card supports these frequencies in the 5GHz range:
* 5180.0 MHz [36] (23.0 dBm)
* 5200.0 MHz [40] (23.0 dBm)
* 5220.0 MHz [44] (23.0 dBm)
* 5240.0 MHz [48] (23.0 dBm)
* 5260.0 MHz [52] (20.0 dBm) (radar detection)
* 5280.0 MHz [56] (20.0 dBm) (radar detection)
* 5300.0 MHz [60] (20.0 dBm) (radar detection)
* 5320.0 MHz [64] (20.0 dBm) (radar detection)
* 5500.0 MHz [100] (26.0 dBm) (radar detection)
* 5520.0 MHz [104] (26.0 dBm) (radar detection)
* 5540.0 MHz [108] (26.0 dBm) (radar detection)
* 5560.0 MHz [112] (26.0 dBm) (radar detection)
* 5580.0 MHz [116] (26.0 dBm) (radar detection)
* 5600.0 MHz [120] (26.0 dBm) (radar detection)
* 5620.0 MHz [124] (26.0 dBm) (radar detection)
* 5640.0 MHz [128] (26.0 dBm) (radar detection)
* 5660.0 MHz [132] (26.0 dBm) (radar detection)
* 5680.0 MHz [136] (26.0 dBm) (radar detection)
* 5700.0 MHz [140] (26.0 dBm) (radar detection)
* 5720.0 MHz [144] (26.0 dBm) (radar detection)
* 5745.0 MHz [149] (23.0 dBm)
* 5765.0 MHz [153] (23.0 dBm)
* 5785.0 MHz [157] (23.0 dBm)
* 5805.0 MHz [161] (23.0 dBm)My router is running at 5260MHz and I can get full link speed to it, but if I try to use the same frequency network manager fails to start the hotspot.
If I select any channel that does not say "radar detection" next to it, the hotspot is created successfully.
So I used a wifi scanner on my phone and can see that the hotspot says 5755-5775 (20MHz) but my router says 5220-5330 (80MHz).
So the second number seems to be key. I understand this relates to bandwidth, but I don't know how to make my hotspot use 80MHz instead of 20.
The Windows hotspot was shown to be on channel 149 (155) at 80MHz. If I choose 149 with NetworkManager, it shows only 149 and 20MHz.
This is the log I get from NetworkManager when trying to use one of the frequencies that fails:

I've managed to solve the problem by following https://finchsec-1672417305892.hashnode … smasq-dhcp and using this configuration for hostapd:
interface=wlp5s0
channel=149
hw_mode=a
ieee80211n=1
require_ht=1
ieee80211ac=1
require_vht=1
ieee80211d=1

vht_capab=[MAX-MPDU-3895][SHORT-GI-80][SU-BEAMFORMEE]
vht_oper_chwidth=1
vht_oper_centr_freq_seg0_idx=155

wpa=2
macaddr_acl=0
ignore_broadcast_ssid=0
wpa_passphrase=somepass
wpa_key_mgmt=WPA-PSK
wpa_pairwise=TKIP
rsn_pairwise=CCMPWith this I'm able to get the full 866mbps.
