AX200 5GHz AP AX mode works, tildearrow's method. #9976

ghost · 2022-08-21T01:43:08Z

AX200 5GHz AP mode, tildearrow's method. No need for lar_disable!

https://tildearrow.org/?p=post&month=7&year=2022&item=lar

here it is with openwrt.

patch cleaned up for openwrt

999-hostapd-2.10-lar.patch.txt

I posted this to share information that its now possible.

ghost · 2022-08-21T01:56:04Z

some more test

wlshdjj · 2022-08-21T02:32:22Z

So, there must be another 5g AP that AX200 5g will work ?

ghost · 2022-08-21T03:37:23Z

So, there must be another 5g AP that AX200 5g will work ?

I think so, since thats how it knows its own regulatory domain. It does 802.11d compliance this way.
We need more tests.

EDIT:

I just managed to bring it up even after turning off all 5GHz radios in the house, so I'm not sure anymore.

also the usable channels is pretty limited

even if you modify wireless-regdb it will not budge, it has some sort of firmware regdomain inside it seems.

ghost · 2022-08-22T10:30:43Z

Wow, so exciting, thank you so much for sharing this.

I added

if (!iface->conf->noscan) {
//scan
}

as you see this is to do the lar scan you have to do option noscan '0'
this will be handled better if lets say you make option lar_scan or something like that.

also wise to add these radio options

option he_bss_color '8'
option he_su_beamformee '1'

from: https://forum.openwrt.org/t/802-11ax-worse-than-802-11ac-with-mt76-driver/126466/50

and it results to this

I don't know the stability of this setup or what not as I only have PCs as ax clients.

I kinda want to share this on right.com.cn (but I don't speak chinese) as it would be nice to see if someone tests this too on their own especially on x86 builds.

wlshdjj · 2022-08-22T12:42:32Z

I have no AX200 to test. All I want to do now is hope to make MT7921 work better.

ghost · 2022-08-22T12:55:22Z

I have no AX200 to test. All I want to do now is hope to make MT7921 work better.

I think AP mode on MT7921 and MT7921K already works.

also on another note, is MT7922 already available in china?

wlshdjj · 2022-08-22T14:16:51Z

I haven't seen anyone selling the MT7922 yet.

aiamadeus · 2022-08-23T02:31:44Z

also on another note, is MT7922 already available in china?

It's available on the second-hand market, but it's rare and a little more expensive.

Hello! Author of the original patch here.
Note that the way I implemented it is a hack which may not work properly sometimes.

SunSgr · 2022-09-07T17:40:31Z

Sure,I got the MT7922 two days ago, but I don't know how to drive it.

ghost · 2022-09-09T16:05:08Z

openwrt/openwrt#10564

you install kmod-mt7921e and then you will need

WIFI_MT7922_patch_mcu_1_1_hdr.bin
WIFI_RAM_CODE_MT7922_1.bin

in /lib/firmware/mediatek

ghost · 2022-09-10T07:30:15Z

my theory on how to make this patch to not affect other radios (non intel 5GHz) goes like this

if (iface->conf->intel_lar && !iface->conf->noscan) {
      do_lar_scan!
 }

999-hostapd-2.10-lar.patch.txt

then add
option intel_lar '1' on /etc/wireless/config
then it should show up intel_lar=1 on /var/run/hostapd-phyX.conf

it already works on hostapd but I dont know the way on how to add it in uci/luci
but I dont know the proper edit to be done on hostapd.sh and other scripts

EDIT:
I think I've got it

so now in radio config you have to

option intel_lar '1'
option noscan '0'
option channel '149'
option country 'XX'

so you can operate this.

Also yep, It does work even if theres no other 5GHz radio broadcasting around. Just set the country properly. (It seems to accept the hint.)
And even if theres other APs around broadcasting the wrong country, channel 149 is always available on all countries except Qatar.
Feel free to try ;)

@aiamadeus @coolsnowwolf I think this is good enough.

please help me, tks! my wrong steps.docx

you need to add the hostapd.sh edit

I have edit /hostapd/files/hostapd.sh, but still phyX self-managed country is CN,Any other comment ?

backslashxx · 2022-12-04T09:33:11Z

@qq897042818 seems about right, cant open an AP on channel 149~161?

qq897042818 · 2022-12-04T11:22:19Z

@backslashxx Yes, only 2.4g 144M is available now

backslashxx · 2022-12-04T14:30:21Z

@backslashxx Yes, only 2.4g 144M is available now

this is right
show me "iw phy"

you can also plainly try to edit /etc/config/wireless

edit these lines

option intel_lar '1'
option noscan '0'
option channel '149'
option country 'CN'

after editing, in ssh,

# wifi reload

if it doesnt work, show me /etc/config/wireless and logread dump

Forgive my ignorance .... I am primarily a Windows user! :P

I looked into this sometime ago and am pleased to see that some progress has been made since then in getting 5Ghz AP mode "sort of" working at least ....

As someone else mentioned above, in Windows 11 you can share your internet connection over WiFi as a hotspot.

I tried this last night on my 12th Gen Intel NUC which has the Intel AX211 wireless card.

In the hotspot settings in Windows it allows you to select either 2.4Ghz or 5Ghz.

I selected 5Ghz and sure enough a WiFi 6 5Ghz network appeared that I could connect to.

That would suggest to me (and I apologise if I've missed something) that the hardware is capable of being a 5Ghz AP

Why would it work in Windows but then it not be possible to do the same under Linux?

Would be awesome if we could make access points out of these WiFi 6 / 6E cards, they're pretty affordable after all!

Or is the Windows "Mobile Hotspot" implementation still with the same limitations outlined above that are on Linux ie. No DFS etc. ?

Were there any 5GHz networks nearby? If so, can you try again under Windows on a 5GHz-less area and see whether the 5GHz option still exists?

Yes there were 5Ghz networks nearby - unfortunately seeing as I live in a built-up suburb I don't have a "5Ghz-less area" to try (where I would have a computer available to test!)

Maybe it works as long as there are 5GHz networks around?

Hi thanks for showing us. Can you help me to implement this change to an OpenWRT x86 instance? I`m trying to use an ax200 card as an AP in a proxmox OpenWRT vm.
