Mediatek MT7921K "Question about AP mode" #66

Open craiganderson opened 2 years ago

craiganderson commented 2 years ago

Using the mt7921e driver on a 5.15.12 kernel for a MT7921K device.

When attempting to bring up an AP hosted with wpa_supplicant v2.11 I get the following error:

wlp3s0: Driver does not support AP mode

Would you be able to confirm (or add to your table) the last kernel version that was successfully tested for the devices listed there? And meanwhile if anyone has successfully used this card in AP mode and can supply their kernel version and environment details, that would be helpful.

Thanks!

Hi Craig,

As hard as i try to keep with all of the details related to the new mt7921 chipsets and drivers, I am not where I would like to be.

I am under the impression that the mt7921k supports 6 GHz and I saw the new k device IDs go in about 3 months ago which means they would not be in kernel 5.15 yet. Are you sure your card is not based on the mt7921?

Can you post the results of the following so I can get a better handle on what you have?

iw list lsusb

My laptop has a mt7921 based card. It is dual band, not triple band like you would get from a mt7921k based card. I just ran iw list and it certainly shows support for AP mode. I'd test but my to-do list for this coming week is overflowing.

I updated to 5.17.0-rc3 for good measure but no change in behavior. I'm for sure using the MT7921K, the 6GHz bands show up in iw list but I can't create AP on any band (not even 2.4GHz), but it looks like this is expected since AP mode does not show up in the listed of Supported interface modes reported by iw list.

Can you confirm that your card uses the mt7921e driver? You can find this under Kernel driver in use for your Mediatek device after running lspci -vv

craiganderson commented 2 years ago

Ok, same driver then.

I'm guessing that at a minimum, the mt7921e driver code needs to be updated to properly recognize the presence of AP mode with the newer WiFi cards.

I'll reach out to the driver maintainer to confirm and report back with my findings.

Thanks

craiganderson commented 2 years ago

The principal dev for this driver got back to me quickly and confirmed that "mt7921 only supports sta (client) and monitor mode at the moment." I'm not sure why your card would like AP Mode support in this case since it sounds like it won't work for any mt7921 devices. Anyway, feel free to update your table with these findings to remove indication of AP mode support.

morrownr commented 2 years ago

I changed AP mode in the PCIe chart to show in progress for the mt7921k.

There is very heavy development going on with the mt7921 driver right now.

craiganderson commented 2 years ago

Sounds good! Hopefully we get something soon.

One other small nit - technically the AX200 and AX210 drivers do support AP mode, it's just handicapped for LAR affected bands. So in the AP Mode row for these, you could say something like "2.4 GHz only" to be more precise.

craiganderson commented 2 years ago

Also I just happened to have a MediaTek MT7921 lying around (same card as you), so I tried it:

But it gives the same results, no AP supported with the mt7921e driver:

    Supported interface modes:
         * managed
         * monitor

I actually had two 7961 cards with different sub-models, 7961:4680 which didn't match yours, and 7961:3802 which did match. However the results were the same for both, and neither showed up with AP mode. I have no explanation for how AP mode shows up on your MT7921 when the devs are telling me the mt7921e driver doesn't support AP mode.

Are you certain the iw list output you pasted above showing AP mode support is coming from your MT7921 and not another WiFi card? Otherwise I'm stumped...

morrownr commented 2 years ago

I am sure. No other internal wifi in that laptop and no usb adapter plugged in. You are just going to have to face the fact that my driver is better than yours. ... he he he. Seriously, I'm running kernel 5.13. I've not checked to see if AP mode is working. I have checked monitor and managed modes. Just because my driver says AP mode is working does not make it so. This site is mostly about USB adapters and there are no USB adapters based on the mt7921 yet so there is very little testing going on at this point.

Sorry for the dumb question, but where is the table with the AP Mode support? Does it also show how many SSIDs are supported? I've been looking everywhere for a document like this and it sounds like it may have been under my nose the whole time! xD

Hi @craiganderson

But it gives the same results, no AP supported with the mt7921e driver:

  Supported interface modes:
       * managed
       * monitor

Word from a source that would know is that the AP mode support should be in the firmware very soon. It appears to me that Mediatek is going as fast as they can and they decided to go ahead and release the firmware and driver with support as you see it so that Linux users would have at least good managed mode support in the short term but are working very hard to get the rest of the parts in as fast as they can. These WiFi 6 chipsets and drivers are incredibly complex. It astounds me how well the 7921 based card in my laptop works given this new generation of wifi.

All indications are that the 7921e and 7921u will be full featured once everything is complete.

Are you certain the iw list output you pasted above showing AP mode support is coming from your MT7921 and not another WiFi card? Otherwise I'm stumped...

Hopefully the above info helped. I still haven't had time to use AP mode but managed mode works great. I am busy. Golden Rule that I learned working on the Realtek drivers: Just because iw list or iw dev says something does not make it so. They probably had forgotten to remove the AP support statement in the version of the driver I have.

So, a little patience and we will have what we seek.

Regards

Hi @craiganderson

Word from a source that would know is that the AP mode support should be in the firmware very soon.

The following was submitted last week:

Update binary firmware for MT7921 WiFi devices

File: mediatek/WIFI_MT7961_patch_mcu_1_2_hdr.bin
Version: 20220311230842a
File: mediatek/WIFI_RAM_CODE_MT7961_1.bin
Version: 20220311230931

I suspect that these new firmware files include the AP support for the mt7921e/u. You can keep an eye on the log at the following site:

https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/log/mediatek

Once you see a new entry for those files then you can go to tree and download them and replace your current versions and see what the results are. Please let us know.

Regards

morrownr commented 2 years ago

Hi @craiganderson

Today the follow patch was submitted. It appears that more than the new firmware was needed to turn AP Mode on:

From: Sean Wang <sean.wang@mediatek.com>

add AP mode support to mt7921 that can work for mt7921[e,s,u]
with the common code.

As you know, I keep a watch on the linux-wireless mailing list. The amount of work required for the WiFi 6 drivers is incredible. As best I can tell Mediatek has all hands on desk in an effort to finish work on the remaining features for the mt7921[e,s,u].

FWIW: I've used Linux since before WiFi, as we know it, existed. If my memory is correct, the mt7921u will be the first USB WiFi driver that will be in the kernel and fully ready to go BEFORE adapters are available.

zzxxtt commented 2 years ago

Hello, Although their's a patch on mt7921 ap mode, It seems it not merged to mainline kernel yet? I installed the latest 5.17.5 kernel and download the latest formware but still not have ap mode in iw list. Any idea how to build it by ourselve, like dkms?

morrownr commented 2 years ago

hi @zzxxtt

After I looked at the date on my message above about the latest commit, I can see the date is only 29 days ago. It won't be in 5.17. It may not have made it into 5.18 but for sure will be in 5.19. It is possible to compile and use a module that is in-kernel, however, that is on my to-do list. I need to learn how to do it. Let me know if you find a good guide.

FYI: I updated my guide about Mediatek firmware:

hi all, I am using RZ608 wifi card on ubuntu 22.04 to set up an wifi access point. I am using netplan and NetworkManager to set the wifi in ap mode. However, devices could not connect to the ap and sudo wpa_cli -i wlp2s0 status shows

bssid=10:6f:d9:af:56:c5
freq=2412
ssid=test
id=0
mode=AP
pairwise_cipher=CCMP
group_cipher=CCMP
key_mgmt=UNKNOWN <- this problem. 
wpa_state=COMPLETED
ip_address=192.168.18.1

key_mgmt should be WPA2-PSK or something else. so is the issue related to the driver mt7921e. how could I fix it, great thanks.

morrownr commented 4 months ago

Hi @zeddit

Recommend that you start a new issue. Very few people will see this issue in this location.

I'd help if I could but using netplan and NM for AP mode is not something I know anything about. I do use AP mode a lot. In fact, I have an AP mode guide called Bridged Wireless Access Point on the Main Menu.

@morrownr

zeddit commented 4 months ago

@morrownr great thanks for your kindness and reply. The problem solved after I changed to use hostapd rather than NetworkManager. It's a problem of NetworkManager. thank you again.

rohithhackthlon commented 1 month ago

any updates about mt7921 ap mode support

morrownr commented 1 month ago

@craiganderson

This is a very old thread that has drifted toward various topics. I have various adapters/cards that use the mt7921u and mt7921e drivers and AP works fine for me.

Recommend you start a new issue with details on your adapter/card, distro and what you are trying to do.
