Help with MT7922 card
Hello all,
I got a MT7922 PCIe card, but i'm having trouble make it work. hostapd fails with:
*wlp4s0: interface state UNINITIALIZED->COUNTRY_UPDATE
Frequency 5180 (primary) not allowed for AP mode, flags: 0x853 NO-IR
Primary frequency not allowed
wlp4s0: IEEE 802.11 Configured channel (36) or frequency (5180) (secondary_channel=1) not found from the channel list of the current mode (2) IEEE 802.11a
wlp4s0: IEEE 802.11 Hardware does not support configured channel
Could not select hw_mode and channel. (-3)
wlp4s0: interface state COUNTRY_UPDATE->DISABLED
wlp4s0: AP-DISABLED
wlp4s0: interface state DISABLED->DISABLED
wlp4s0: AP-DISABLED

hostapd_free_hapd_data: Interface wlp4s0 wasn't started
nl80211: deinit ifname=wlp4s0 disabled_11b_rates=0*
.

.
I uncommented the respective lines in hostapd.conf for MT7921, which should work for this MT7922 (but does not):

Okay. This is like being taken out of elementary school so you can start work on a PhD.
I just saw where the mt7922e cards were shipping recently. What I think I know about the mt7922:
- it is the mt7921 except that it supports 160 MHz channel width
- we may see a mt7922u at some point but let's not forget that USB is always last
- the mt7922 is supported by the mt7921 driver
- the mt7922 has its own firmware (not the same as the mt7921) (have you upgraded it?)
Does the adapter work in managed mode? If so, which bands have you tested?
What does iw dev show?
You must have the driver going because I see:
Supported interface modes:
* managed
* AP
* AP/VLAN
* monitor
So, that seems to indicate AP mode is supported.

Rocky linux 9.1. Just a mini-pc with this chip on a PCIe card. Guide? This very own guide. Kernel have the right driver, so i just need the right hostapd.conf file. Oh, and better antennas :) Oh, i do have the comfast 953-ax, but that's in case i don't manage to make this card work.
EDIT: Using the full line works: ht_capab=[LDPC][HT40+][HT40-][GF][SHORT-GI-20][SHORT-GI-40][TX-STBC][RX-STBC1][MAX-AMSDU-7935]
iperf3 reports 2MB/s with reverse 10MB/s
EDIT2: Using these new settings for testing 5GHz, does not work:
hw_mode=a channel=36 vht_oper_chwidth=1 vht_oper_centr_freq_seg0_idx=42 vht_capab=[SHORT-GI-80]
Fails with:

These are the most basic 5GHz settings, right?
Do you need wpa3 for wifi6?
No. WPA3 is mandatory for WiFi 6e but not WiFi 6.
Rocky linux 9.1. Just a mini-pc with this chip on a PCIe card. Guide?
I have the Bridged Wireless Access Point guide in the Main Menu but I don't know if that is what you want to do.
I am not familiar with Rocky. AP mode, like monitor mode, will have problems if certain procs are left running... Network Manager for example.
Have you thought about trying OpenWRT? If has the mt7921e driver backported to kernel 5.10. You might have to add the firmware but I have a guide up for that.
Do you need wpa3 for wifi6?
No. WPA3 is mandatory for WiFi 6e but not WiFi 6.
Ok, so does the mt7921 driver/module support wpa3? Does this mt7922 support it? hostapd? I'm assuming yes, otherwise they wouldn't market it a 6e capable device, right?

I managed to have a TPLink usb wifi dongle working on another pc with your config. However on this one i'm having trouble have it working. Same hostapd.conf. Same usb dongle. I suspect the kernel module. I'm on 6.2.1. Realtek drivers already on it.
Ok, so does the mt7921 driver/module support wpa3?
Yes. In fact, all in-kernel drivers that I have tested support WPA3. That includes adapters all the way back to ra3070, ra2870, and more. I actually have a lot of adapters.
Does this mt7922 support it?
Yes
hostapd?
It depends on the version you are using.
I'm assuming yes, otherwise they wouldn't market it a 6e capable device, right?
Well, marketing, logic and truth have a loose relationship.

The guilty parties might be wpa_supplicant or Network Manager or something else in the distro. You can run the kernel up to the latest but that does not upgrade others things are needed to be modern for WPA3 and other modern things to work. My basic advice is if you have a distro that was released after mid-2022, you should be good. There are exceptions. What are you using?

Downgraded the kernel to 6.1.9, which doesn't have the realtek drivers and compiled your drivers, 88x2bu-20210702, the tplink dongle is working. Not at full blast, but it's ok. However, i would like to have this mt7922 card working. Maybe the mediatek drivers in the kernel 6.2.1 suck just like the realtek ones?
So now the card works. No idea why it started working. Anyway here is my hostapd.conf file.

Ok, but i'm giving up on this card. I guess the drivers are still bad. I used the 6.2.1 kernel and latest firmware. The connection is kind of "funky", also 20ms+ pings. Sometimes hostapd does not start, etc. No wpa_supplicant and Networkmanager was stopped.
Funny because you were saying mediatek is more stable than realtek. I'm finding the exact opposite. The TPLink dongle i got, is much more stable than this card and comfast 953-ax. 2-3ms pings. Plus, i'm compiling the module for Red hat original kernel, 5.14, not mailine. That comfast dongle is even worse than the card. Complete disapointment. I tried, i really tried.
Maybe i screwed up with the PCIe card, because the antenna plugs were so damn tiny, but at a time iperf3 was showing 40-50MB/s, normal and reverse. So afterall the antennas are correctly working. As for the comfast dongle, it has no excuse to suck so much :) Very unstable.
Rocky Linux 9.1 elrepo kernel-ml 6.2.1, it can't be more recent than this.
Realtek 2 Mediatek 0
Red hat original kernel...
Rocky Linux 9.1
This could explain a lot. There is a reason that I specify that Red Hat/RHEL and any distro that is based on RHEL is not supported by the Realtek drivers we have up here. There two reasons:
-
Red Hat does some things with their kernels that make it very difficult to support with out-of-kernel drivers. There are many good distros for running hostapd, RHEL is not one of them.
-
Red Hat prioritizes extreme stability. That is good for their target market. Running hostapd is about as far away from Red Hat's target market as you can get. A large part of that stability comes from basing on kernels and other parts that are old. That makes trying get WiFi6/6e and WPA3 going almost impossible...without a deep dive into the various components that support those functions. I'm amazed that you got as far as you did. There is far more than a stable driver that is required to make what you were trying to do work.
Maybe i screwed up with the PCIe card
I don't know that this is what happened as I don't think you can properly judge that based on the distro you are using. I've been running Linux since 1994 and if you asked me to do what you are trying to do with RHEL, I would just break out in a cold sweat and take off running.
What I have found is that if users that have a specific project in mind , they should ask for suggestions first, there are those here than can make recommendations that are likely to increase the chances of success. Do I think you can have success with your card? Yes, but it is not likely right now due to the use of bleeding edge hardware on a distro that can be problematic with 10 year old wifi hardware on your end and a lack of knowledge of what you are really wanting to accomplish on our end.
If you decide to give things another try, first explain what end goal/end state you are trying to accomplish and we can see where it goes.
Good luck
So, ok. My end goal is to set an AP. 5Ghz only. Decent speeds, decent pings.
I have 3 devices i can use:
- MT7922 m.2 card (i said before it was pcie, my mistake)
- Comfast CF-953AX with MT7921
- TP-Link T3U Plus
MT7922: Even tough i'm running Rocky 9.1, the kernel, as i said, was mainline 6.2.1, released one week ago or something. So, the argument Red Hat is playing safe, does not apply here. The card/glue patched antennas are correctly installed, i got 50 MB/s on iperf. And again, these are crap antennas. However pings were crap. When i modprobed the module with disable_aspm, the system freezed. I find it strange, the modules have just one or two parameters.
Comfast: Too much crapness, very unstable connection, sometimes it didn't even connected. On hostapd.conf i used the config for mt7921. Cheap is cheap i guess.
TPlink: Realtek sucks eh? With your drivers 88x2bu-20210702, not here. I'm using Rocky/Red Hat's default kernel, 5.14.0-162.18.1.el9_1.x86_64. Pings are low and stable, speeds are enough.
Realtek wins. Mediatek can update their drivers as often as they want. For AP, the chips suck. In my experience, mediatek always sucked, i have tried phones with their chips. They sucked.
Maybe i'll try qualcomm later. Pitty intel does not support AP in 5Ghz.
Apologies if i sound mad, that's because i am :) I bought the mediatek stuff, because of recomendations here.
Apologies if i sound mad, that's because i am :)
I get that. It happens.
I started this site with a primary goal of getting good information to the Linux community. WiFi is a complicated subject and there are many ways that USB WiFi adapters can be used. At times, I have to make changes to the information that is available. If the information here has caused you to see less than excellent results, I'm all for getting to the reason so that the information here can be modified.
My end goal is to set an AP. 5Ghz only. Decent speeds, decent pings.
The speeds and pings depend on a lot of things besides driver and wifi chipset.
If I know your country then we can look at what 5 GHz channels are available to you? Have you taken a look at the congestion levels on the various 5 GHz channels? Are you able to use DFS channels? IOW, do you have clients that can't use DFS?
I have the following speed test up:
https://github.com/morrownr/USB-WiFi/blob/main/home/Speed_Comparison_Test.md
That test is conducted on a DFS channel that has no other AP operating. It is clean air. If I were to do the same tests on channel 36 or 149, oh my, the results would look much different because there are other APs working. Remember that WiFi is a technology based on sharing.
Should we perform an analysis to see what channels would be best for you to use? I rescanned this thread but do not see what kind of computer you are using? Are you locked into Rocky or are you open to other distros?

Not as good but not that bad. Wireless is faster.
The problem with the mediatek stuff, was not the bands. I was using the same hostapd.conf file i use for the tplink adapter, just with ht and vht settings specific for the mediatek stuff. tplink works ok, mediatek not. Latest drivers and firmware. Pc is a mini-pc.
In resume, with the m.2 card, pings were high, but speeds were actually good, 50 MB/s. Strangely enough, my phone showed a 5 icon instead of 6. My laptop too, showed AC instead of AX. The chip is supposed to support wifi6/ax.
The comfast adapter was just crap, sometimes hostapd wouldn't even start. It was bad.
I'm happy with tplink, maybe later i'll try again with mediatek.
The chip is supposed to support wifi6/ax.
It does.
That does not mean it is easy to configure for those without a high level of skill yet. For hostapd, you need to download and compile the dev version in order for AX to even be available to be turned on. Not to mention numerous others .config settings that have to be correct. You can't just install hostapd and expect it to work with WiFi 6 yet. I have a guide about how to do this.
The bottom line is that the hardware and driver support WiFi 6 and WiFi 6e in AP mode. Very few distros have versions of hostapd and other requires things that are at levels to support it yet. You have to compile you way to it. The latest RasPiOS was released about 2 weeks ago. It STILL does not have a version of hostapd that will support WiFi 6. I had to compile hostapd for my Pi4B to use my 951AX in WiFi 6 mode. Hell, I had to compile the entire kernel as the RasPiOS still comes with kernel 5.15.
In Main Menu item 2, I wrote at length telling anyone that read it that if a person wants plug and play, they need to move on down to the AC1200 section. This still holds true. If you are technically proficient, go for it. Otherwise, stay away. This is a hard upgrade because 3 things are happening at once: Wifi 6, WPA3 and WiFi6. This is not a Linux, Windows or MacOS problem. It is an overall problem because of the complexities.
The tp-link adapter you are comparing with is a WiFi 5 adapter. You are comparing apples to oranges. Grab a WiFi 6 usb Realtek adapter and compare it to the 953AX. If you want something to compare to the tp-link adapter, grab and Alfa ACM and tell me which adapter is easier to use and maintain after about 6 months. That would be comparing apples to apples.
Cheers

Can you please share the guide's page? Already compiled hostapd, but don't know the settings for wifi6.

Well, like i said, this tplink adapter is fine for me, but if i could manage to get the this mediatek chip to work, would be great. Plus, would help anyone wanting to do the same.

Understood.
I got a mini-pc what came with a realtek 8821ce. Is it any good?

The guide is tested on Raspberry Pi OS which means it is Debian oriented but you can likely work through that. Ask if you don't understand something.
I just thought about this: you will need to compile wpa_supplicant` as well to get WiFi 6 support. Need a guide? This depends on your distro as Ubuntu 22.10 and later are all moved from wpa_supplicant to IWD so this doesn't apply.
WiFi 6e is likely a bridge too far right now. Have you checked reg.db to see if the 6e band is legal in your country? This is a real problem around the world as many countries around the world have not even passed laws making 6e legal yet. The EU seems to be far ahead of the rest of us.
Right now the goal should be getting WiFi 6 going. 6e is another level of complexity. I'm not even up to speed on 6e in AP mode yet. I'm working on it.
My day job is rocket science but this is far more difficult. Just kidding about my day job but not about the level of difficulty. My guess is that this stuff will mostly be sorted out by the time we see Ubuntu 24.04. We have good chipsets with the mt7921 and mt7922 and the Linux driver is already good and improving. It is all the other stuff that is coming up to speed slowly. Remember that you are on the bleeding edge... me too.
Understandable.
My list was not complete as wpa_supplicant needs to be compiled and the two mt firmware files need to be updated by hand and there is more. Installing kernel 5.19 or later is one little part of this puzzel. And we have no prior art to help us. We are the bleeding edge.

Unknown. I almost exclusively work with usb adapters.
It might help if the goal were to be getting a good solid 5 GHz AP working with this adapter and then we can proceed to WiFi 6.
Ok, i got news. After the comfast fiasco, i decided to give this card another try, because i saw on the kernel changelog some changes were made to the mt7921 driver. So i'm running Rocky 9.1 with kernel mainline 6.2.6 from elrepo.
I get 40+ MB/s normal and close to 70 MB/s on reverse. The high pings seem to come from some power saving action from the chip, because as soon i start youtube streaming or even pressing continuously Enter at a ssh prompt, pings lower to 2ms or even less. Executing iperf3 will get them higher as the link gets saturated of course.

What is "normal" and "reverse"? How do you get MB/s from iperf, I get Mbit/sec.
Even tough, iw list shows this card supports 160Mhz and 80+80, it fails with vht_oper_chwidth=2 and 3, for 160Mhz and 80+80 Mhz respectively.
Configured VHT capability [VHT_CAP_SUPP_CHAN_WIDTH_MASK] exceeds max value supported by the driver (2 > 1)
On vht_capab it accepts [SHORT-GI-160][VHT160], but not [VHT160-80PLUS80].
What is "normal" and "reverse"? How do you get MB/s from iperf, I get Mbit/sec.
I'm talking about iperf3. iperf3 -f M -c server will show in MB/s.
In normal mode, iperf client sends data, with reverse (-R), iperf downloads from server. iperf3 -f M -c server -R
iw list shows this card supports 160Mhz and 80+80
I think I remember seeing a patch 1-2 weeks ago in linux-wireless that removed 80+80. I think the discussion was that it supports 160 but not 80+80, at least at this time. So, that tells me the capability was added by mistake.
FYI: There is a lot of ongoing work on the mt7921 driver. We should see P2P capability in the wild soon. Since last fall, we have been seeing new firmware files coming monthly... never seen that before but then wifi drivers have never been this complicated before. The various versions of the mt792x chipset are going into stuff all over the place... TV's, etc.
Hi @fs30000!
I saw you in your hostapd example than you've set Portugal as country and it has same bands locked as Spain (where I am).... May I ask you how you were able to start hostapd in channel 36? I saw you in your first log "wlp4s0: IEEE 802.11 Hardware does not support configured channel"
I ask because I have a AX210 card and I just can start hostapd for 5GHz in channels from 149 to 157 or similar, but in this case is due Intel shitty LAR implementation. And these channels have a very limited power output so they are useless for a home made router.
I was thinking on buying a mt7922 card in aliexpress but I don't know if it will work well as I want.
Thanks in advance!
Yes, 36 works here. In the begining it was failing because i did't have the right config done. I have it now, working fine. However just wifi5, no AX. For wifi6, like Nick said, you need a recent build of hostapd. 5 is enough for me.

I bought the exact same card but I'm getting slow speeds (for a Wi-Fi 6 card, I mean).
I used this exact conf as a template (modifying the interface id and country code, only) and I'm getting ~150Mbps during iperf3 tests from Wi-Fi 6 client to the host, in both directions (send / receive).

I tested the card in client mode and I get top speed from my previous Wi-Fi 5 (2x2) hotspot = ~600Mbps
Also tested different distros and another host machine, just in case, but the results were the exact same. My primary goal was using it on OpenWrt but I can't manage to get it working - I want to believe it's because 23.05 is on rc stage, didn't test on 22.03.
