@wineway You've probably figured it out yourself, but there are two options:

• use this patch to bring back the lar_disable=Y option to iwlwifi

• use this patch to workaround the stupid limitation in hostapd

@wineway You've probably figured it out yourself, but there are two options:

* use this [patch](https://github.com/torvalds/linux/commit/c545b26dd567a638d62ca29490e9e2e6d04a8b6b) to bring back the `lar_disable=Y` option to iwlwifi

* use this [patch](https://tildearrow.org/?p=post&month=7&year=2022&item=lar) to workaround the stupid limitation in hostapd

I also have the AX201 wifi adapter and tried several months ago using the NetworkManager Hotspot on Ubuntu Server 22.04 and maxed out at a little bit over 100 megabit wifi speeds.

I saw this last week and I tried both of these individually and together with hostapd on Ubuntu Server 23.04 and the fastest I can get is with around 75 megabit speed using any combination with the module modification or hostapd installations.

I recompiled/installed the module modification along with a new kernel with "options iwlwifi lar_disable=1" in /etc/modprobe.d with hostapd.

i also used the apt-get source version of hostapd to run the patch and build the debian package to install it (eg dpkg-buildpackage). apt-get source downloaded the source for hostapd and wpa-2 together as a single tree and the only issue was a required commit message before compilation.

also: the config: "vht_capab=[MAX-MPDU-11454][VHT160][RXLDPC][SHORT-GI-80][SHORT-GI-160][TX-STBC-2BY1][RX-STBC-1][SU-BEAMFORMEE][MU-BEAMFORMEE]" doesn't work together per systemctl & journalctl, but each parameter works fine individually; however MAX-MPDU-11454 doesn't work at all. i got different error messages all pertaining to incompatible parameters depending on the multiple permutations of re-ordering or reshuffling i tried and confirming that they were correct with iw list didn't seem to matter.

i leave this here for anyone else who wants to try and can know what DOESN'T work. i will post an update if troubleshooting yield any results.

I spent a week working on a solution that I was happy with and I decided to post github

Hello, this patch works for 6ghz ?

Hello The patch doesn't enable 6ghz or any other bands itself. Only forces Intel drives to recognise the country so that it allows the right bands. So maybe it works for your use, I haven't test it Sent from Proton Mail Android
