July 2022 Comfast CF-953AX - chipset: mt7921au (single-state) (BT 5.2) http://en.comfast.com.cn/index.php?m=content&c=index&a=show&catid=13&id=182

July 2022 Comfast CF- 951AX - chipset: mt7921au (single-state) (BT 5.2) http://en.comfast.com.cn/index.php?m=content&c=index&a=show&catid=13&id=209

October 2022 Netgear A8000 AX3000 USB Adapter - chipset: mt7921au https://dongknows.com/netgear-a8000-ax3000-usb-adapter-is-here/

February 2023 ALFA AWUS036AXML https://www.alfa.com.tw/products/awus036axml?variant=39754360684616

EDIT: 2022-07-22 - Important info: The above adapters use the mt7921u driver. The mt7921 base driver has been in the Linux kernel since 5.12 so internal cards have been working well for some time with the exception of AP mode. The above are usb adapters and usb support was not added to the mt7921 driver until kernel 5.18. Most of the more popular distros provide instructions for upgrading kernels. I can provide instructions for Ubuntu based distros on request. AP mode support was added in kernel 5.19. It requires a firmware upgrade, see Main Menu 8.

EDIT: 2022-07-22 - We now have reports from @foen73 and @yaslama about the CF-953AX. Both report that it is a single-state adapter. That is very encouraging.

EDIT: 2022-08-03 - FYI: I see from an ad that the chipset is called mt7921au. This is the first time I have seen that specific name. It appears the mt7921au chipset has the same capabilities as the mt7921k that we have known about for some time.

EDIT: 2022-07-22 - Disclaimer: While we do have limited positive reports at this point, there could be issues that have not been discovered yet.

Regards,

Nick

I'm feeling a sudden urge to both jailbreak this thing AND put a 2kW hamradio linear amplifier just to make a statement...

Hmmm...

@yaslama

Which version of OpenWRT are you using?

Are you able to use the 953AX as an AP with 6 GHz?

The AP is configured but I still wasn't able to connect to it (at 5Ghz it was ok). I see the the ssid but, the the connection fails. I ordered some 7921k m.2 cards to test.

My WDR4300 with OpenWRT 22.03 and kernel 5.10 is much more liberal, even has the mt7921u module and is loading it to the correct USB device, but iw isn't recognizing it for some reason. Probably the USB2.0 port? I can try flashing the nightly snapshot of OpenWRT into the RPi4B.

I'm running 22.03 on my Zyxel wifi router. I had not thought to check for the driver since it is running kernel 5.10. I smell a backport:

kmod-mt7921u

Probably the USB2.0 port?

I doubt it. Is the firmware installed?

Done.

It's a backport, but it worked. I had to manually download the firmware though. I will prepare some performance tests later on.

You might want to report the issue with lack of firmware package to:

https://github.com/openwrt/mt76

It is not like the OpenWRT folks don't know the firmware is needed as a couple of the OpenWRT devs work in linux-wireless. It could be that they are not aware that there has been a public release of mt7921au based adapters and we need that firmware package available in 22.03.

Here is the direct link to where I give instructions for the installation of the latest firmware files:

https://github.com/morrownr/USB-WiFi/blob/main/home/How_to_Install_Firmware_for_Mediatek_based_USB_WiFi_adapters.md

Obviously you have already done it but others that read this later may want to know.

Cool.

What does iw dev look like now that the firmware is installed?

@morrownr Nothing there just yet. I haven't connected in the other adapter yet, and if I connect on my own AP it is likely to restrict allowed bands again.

Are you able to use the 953AX as an AP with 6 GHz?

The AP is configured but I still wasn't able to connect to it (at 5Ghz it was ok). I see the the ssid but, the the connection fails.

Good news. I have a connection between debian (CF-951AX) and openwrt running in a rpi400 (CF-953AX) using the channel 53 (6215 Mhz). The distance between them is about 50cm and I obtain about 410Mb/s in iperf3. If you need more info and/or tests, I can do that.

Thanks for the offer. I think the two most important things that viewers would appreciate right now are:

https://github.com/morrownr/USB-WiFi/blob/main/home/USB_WiFi_Adapters_that_are_supported_with_Linux_in-kernel_drivers.md

FYI: I have not added the 951AX yet as I have enough reports on the 953AX to feel comfortable with adding it to the list but am waiting for more reports on the 951AX

adriangranados commented 2 years ago

My interest in these adapters is just from a troubleshooting point of view: being able to scan for wireless networks and capture Wi-Fi traffic. I can confirm monitor mode works well in the CF-953AX in all 3 bands: 2.4, 5, and 6 GHz (US regulatory domain).

On 6 GHz, it can capture traffic using 20, 40, and 80 MHz. You can set 160 MHz, but only malformed frames are generated.

Also, reported "antenna signal" (RSSI) values are way off, unfortunately, but Mediatek is aware of this issue and looking into it.

Very promising as the first Wi-Fi 6/6E USB adapter I've been able to use for capturing.

The firmware is is packaged with kmod-mt7921e so you can either install this package to have the firmware or install it manually.

I'll try to post a pull-request to package the firmware in its own package and have both kmod-mt7921e and kmod-mt7921u depend on it or maybe move it to mt7621-common when I have time...

My CF-953AX is on its way from China and should be there soon to replace one of my Alfa Network mt7612u adapter.

morrownr commented 2 years ago

Hi Adrian,

Thanks for the report. I'm sure it will be read by many.

My interest in these adapters is just from a troubleshooting point of view: being able to scan for wireless networks and capture Wi-Fi traffic. I can confirm monitor mode works well in the CF-953AX in all 3 bands: 2.4, 5, and 6 GHz (US regulatory domain).

We needed a good report on monitor mode and this report provides additional confirmation that this adapter is indeed a tri band adapter.

On 6 GHz, it can capture traffic using 20, 40, and 80 MHz. You can set 160 MHz, but only malformed frames are generated.

The mt7921 chipset does not support the 160 MHz channel width. It is the next step up, the mt7922 chipset that supports 160. If I am reading the messages correctly, the mt7921 driver already supports the mt7922 chipset...but I have yet to see any products, PCIe or USB released with the mt7922.

Also, reported "antenna signal" (RSSI) values are way off, unfortunately, but Mediatek is aware of this issue and looking into it.

Copy all. Good info. I am convinced that Mediatek will work hard at fixing the issues and some issues only show up with the release of the product. I monitor linux-wireless and the best analogy I can come up with is the Ham and Eggs Breakfast. The chicken is involved but the pig is committed. I think you know which of the two companies is which.

Very promising as the first Wi-Fi 6/6E USB adapter I've been able to use for capturing.

This sounds good. I am curious as to your opinion of the range of the 953AX. Any thoughts?

The firmware is is packaged with kmod-mt7921e so you can either install this package to have the firmware or install it manually.

This is good info. I did not think about that but the devs do need to be consistent in how they are packaging things, It does not take much to confuse me. he he

That reminds me. I need to download the Ubuntu 22.10 that is indevelopment to test to see if it is up to speed with the latest firmware. If not, I can post a bug so maybe the new release will ship as plug and play. Users of other distros need to think about doing this also.

Hey @coudu

Hopefully that works its way in soon. Thanks for doing that. My plan is to add 6 GHz capability to my main wifi router as soon as I have two good adapters. What I want to know is where is ALFA? Come on ALFA, we are waiting!

Same here, I was a bit worried when I had to move from ath9k/ath10k cause I needed the mpcie slots for SFP and 2.5Gbe, but I have two Alfa AWUS036ACM (one for 2.4, one for 5Ghz) and they have been quite amazing on stability/AP runtime being USB adapters. I would also like an Alfa made 6Ghz one because their products are very well made.

Thanks @morrownr for "centralizing" all these infos.

The patch still needs to get approved, but made the changes by hand, tried them and got correct RSSI measurements 🥳

I have received my CF-953AX. Shipping to the US East coast was took around 2 weeks. I'm using it as AP instead of the Raspberry Pi 4 Broadcom BCM2711 chip. It works mostly well with the following hostapd config:

The speed differential grows with distance.

However, there is one significant problem with the CF-953AX / MT7921U / hostapd: If I move one of the clients out of range from the AP while running a speedtest from that client, the client will eventually (after a few seconds) disconnect and the AP will hang forever until hostapd is be restarted. dmesg shows (# indicate my annotation):

I plan to email Lorenzo about this issue, as he wrote the driver https://lwn.net/ml/linux-wireless/cover.1647188301.git.lorenzo@kernel.org/ Please let me know if you have other suggestions. For example, if you think this is rather a hostapd issue than a driver issue.

morrownr commented 1 year ago

Hi @leezu

if you think this is rather a hostapd issue than a driver issue.

Can I get you to post the full output of "iw list" so that I can use the info to dig into the hostapd docs? I don't know at this point because I don't have an adapter based on the mt7921au chipset yet but I do have a lot of experience with hostapd so I might be able to make some suggestions.

Are you trying to use 5 GHz? What channel width are you trying to use?

Nick

leezu commented 1 year ago

Thank you, @morrownr! I'm trying to use 5 GHz on channel 36. The full output is at iw_list.txt Preparing the output, I noticed that I mistakenly referred to BCM2711 Capabilities and VHT Capabilities when preparing the CF-953AX hostapd configuration. These are the corrected capabilities:

ht_capab=[LDPC][HT40+][GF][SHORT-GI-20][SHORT-GI-40][TX-STBC][RX-STBC1][MAX-AMSDU-7935]
vht_capab=[MAX-MPDU-7991][RXLDPC][SHORT-GI-80][TX-STBC-2BY1][SU-BEAMFORMEE][RX-ANTENNA-PATTERN][TX-ANTENNA-PATTERN]

The correct capabilities improve the throughput by ~25% and improve the range, or at least the chip does not crash/disconnect anymore when I reach the same distance. However, I did see another hang / crash that required me to restart hostapd, but I'm not yet sure how I triggered it. The output is

I'm trying to use 5 GHz on channel 36.

Good idea to optimize that while we figure out how to handle 6 GHz.

From hostapd.conf above:

channel=36

Recommend:

# Channel
channel=36
# Channel width
vht_oper_chwidth=1
# VHT center channel (chan + 6)
vht_oper_centr_freq_seg0_idx=42

That should take you into 80 MHz channel width mode.

Recommend you add the following:

# Advertises the country_code and the set of allowed channels and transmit power levels
ieee80211d=1
# Enables support for 5GHz DFS channels (requires ieee80211d=1)
#ieee80211h=1

We should check to see if DFS channels are working in AP mode.

mt7921u 2-1:1.3: timed out waiting for pending tx

At this point, I am no help with that.

Question: Does the LED flash?

Nick

leezu commented 1 year ago

Thank you, @morrownr! Enabling your recommended settings worked. Did you mean #ieee80211h=1 or rather ieee80211h=1? How do you suggest to check if DFS channels are working in AP mode?

mt7921u 2-1:1.3: timed out waiting for pending tx

The LED remains on constantly.

morrownr commented 1 year ago

How do you suggest to check if DFS channels are working in AP mode?

Change settings to reflex a DFS channel for your country. I see your country setting is US so:

DFS FCC 80 MHz channels for hostapd: 52(58), 100(106), 116(122) and 132(138)

Example using channel 100:

# Channel
channel=100
# Channel width
vht_oper_chwidth=1
# VHT center channel (chan + 6)
vht_oper_centr_freq_seg0_idx=106

You will also need to uncomment the following line as shown:

ieee80211h=1

save and reboot then check to see if you can connect. Note: DFS channels require a 60 second delay to make sure there is not something on the channel that should make the channel unusable so you won't see the ap for at least 60 seconds... you have to wait. I'm hoping DFS works on 5 GHz as it is very handy depending on the local wifi situation. This message is coming to you via DFS channel 52(58). It is clean air here and my mt7612u based adapter that is in client mode shows ~400 Mb/s as shown by iperf3. WiFi can really go fast in clean air. The mt7612u chipset has not supported DFS in AP mode so I am hoping the new chipset, mt7921au, does support it. Let us know what you find out.

Enabling your recommended settings worked

You may see higher speeds now that you are using 80 MHz channel width.

leezu commented 1 year ago

Nice, thank you @morrownr! I'm in contact with Deren from Mediatek regarding the hang, which also persists with the latest firmware. I'll keep the current setup running for a few days to gather more information about the situations in which the hang occurs / the frequency of occurrence and also see if Deren has a quick fix for this particular issue. Following that, I'll proceed and try DFS based on your suggestion.

adriangranados commented 1 year ago

@leezu Not sure if related, but there's been some activity in OpenWRT about a bug that causes some halting condition when a client leaves a Wi-Fi network, plus some other regressions that have been apparently fixed in the last days.

Dave Taht on a post on LinkedIn:

I have been working on the "make wifi fast project" now for going on 10 years. In the last 6 months we untangled a string of regressions in the openwrt (and #linux mainline) stack that entered the "stable" 21.02.2 and .3 releases, which I think are now fixed in 22.03-rc6. If anyone out there has been struggling with #openwrt's #wifi for the last 9+ months, I apologize. And if you or anyone you know could step up to #help #test 22.03-rc6, especially if you use the #ath9k, #ath10k, or #mt76 wifi chips in your #router, I'd really appreciate it.

The post then points to https://forum.openwrt.org/t/aql-and-the-ath10k-is-lovely/59002/831

Just thought I'd share.

There are some AP mode issues in v5.19 stable tree. The fix is mainline ready and would be post to v5.19.y later. If you want to run AP mode now, please take the patch below and update to latest firmware. :) mt76: mt7921: fix command timeout in AP stop period

haevalencia commented 1 year ago

I am surprised by the good community that there is here.

UnknownProgrammer commented 1 year ago

This seems to be the place to talk about the CF-953AX so I will share my experience using it with Ubuntu 22.04 as simple wifi client.

I bought the CF-953AX to replace my CF-955AX, which I'm currently using with this driver https://github.com/lwfinger/rtl8852au, with something that offers a in-kernel-driver.

To test the CF-953AX with 22.04 I installed kernel versions 5.18, 5.18.15 and 5.19 from https://kernel.ubuntu.com/~kernel-ppa/mainline/.

At first I used the firmware already provided by 22.04.

The router is ax capable -> Fritzbox 6660 cable set to channel 36 at 5Ghz. Channel width can't be changed and can be up to 160Mhz.

The client is set to use only the 5Ghz band.

The distance from client to router is around 7m with two thin ceilings between.

Results:

Kernel 5.18 didn't have stable throughput rates. They where fluctuating between 50 and 300 Mbit using a two minute connection test to the router with iperf.

So I switched to 5.18.15. Throughput became stable at ~300 Mbit. But after about two hours the client got deauthenticated from the router (Reason: 16=GROUP_KEY_HANDSHAKE_TIMEOUT) and a reboot was necessary to reestablish the connection.

After that I tied 5.19 (Daily/current -> 2022-08-11). Throughput stayed at ~300 Mbit. Client got deauthenticated after about two hours again.

As next step I replaced the provided firmware (Files: BT_RAM_CODE_MT7961_1_2_hdr.bin, WIFI_MT7961_patch_mcu_1_2_hdr.bin, WIFI_RAM_CODE_MT7961_1.bin) with the ones here https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/mediatek. Checking the size and date on the files showed that they differ from the included ones. Even with the new firmware the client got deauthenticated again, sadly.

The CF-955AX works stable on the same port at the same location, but with ~110 Mbit less throughput compared to the CF-953AX. No other wireless client has issues with deauthentication.

That's it. No happy end, so far. Maybe this helps somebody.

I have been surprised at how many people use this site. I had known there was need for better usb wifi support for many years and the begiinning of COVID-19 gave me a good excuse to start working on something and it has evolved based on input from many people and help from many people.

Hi @UnknownProgrammer

I think it would work better if you started a new issue for just this issue as this thread has grown so long that many will never read this far. You can copy most of what you wrote above into the new issue. A good title would attract others with the CF-953AX. Maybe something like this:

CF-953AX dropping connection with Fritzbox 6600

Some other questions that might help with the issue:

Have you tested with other bands? 6 GHz and 2 GHz? Results?

Have you tested on alternate 5 GHz channels?

Have you upgraded the firmware in the Fritzbox to the most up to date version?

If we can get verification that this is a driver issue, we can make a report to the Mediatek kernel devs.

Regards,

Nick

UnknownProgrammer commented 1 year ago

Hello @morrownr

took a while to perform the tests to answer your questions.

Have you tested with other bands? 6 GHz and 2 GHz? Results?

Set client to 2.4Ghz fix with the same result -> connection drop after 2-3 hours.

The 6660 is only a wifi 6 device not wifi 6e.

Have you tested on alternate 5 GHz channels?

Set the router to channel 100 -> also connection drop after 2-3 hours.

Have you upgraded the firmware in the Fritzbox to the most up to date version?

Firmware version is the latest 7.29. But the firmware is controlled by the cable provider, which takes quite some time to review and deliver the manufacturer firmware.

Looks like the time-out timer for rekeying is set to 3 seconds, because the deauthentication happens 3 seconds after the rekeying should have happened.

Would be nice if the driver had some recovery mechanism to reestablish a connection after deauthentication.

Thank you for your interest, I will open a separate issue.

Anima1000000 commented 1 year ago

Thank you for writing the instructions of adding a firmware. Aside from the firmware is there a foolproof way of manually installing the mt7921u driver in the kernel? The latest Raspberry Pi OS doesn't yet have the drivers included.

morrownr commented 1 year ago

Hi @Anima1000000

Thank you for writing the instructions of adding a firmware.

Glad it helped.

is there a foolproof way of manually installing the mt7921u driver in the kernel?

The only practical way to install the driver (module) is to upgrade the kernel. Here is a guide for Ubuntu:

https://itsfoss.com/upgrade-linux-kernel-ubuntu/#ukuu

...but don't use that guide as the mainline kernel probably does not yet include some drivers that are included in the RasPiOS. I would have to investigate to see what options are available for the PiOS and I am very busy today patching some drivers. You might post a msg on the appropriate RasPi forum and ask how to upgrade the RasPiOS kernel to 5.19 so as to get driver support for your new adapter. If you don't have luck that way, come back and check in with me next week. I may have time then.

Nick

morrownr commented 1 year ago

@Anima1000000

I had a thought: What are you doing with that Pi? If you are running an AP, OpenWRT 22.03 already has the driver. The devs backported it to kernel 5.10.

morrownr commented 1 year ago

@yaslama @leezu @deren @bcdonadio @coudu @amisix @adriangranados

Good day all,

This is a broadcast message to many of those involved in this thread. Some of you already have cf-953ax or cf-951ax usb adapters that feature the mt7921au chipset. My cf-951ax arrived yesterday and I have been testing it.

So far the results are not good. In fact, the results are so bad that I need to do some comparisons with your results to see if I have a faulty adapter so I can return it.

My system is amd64 running Linux Mint 21 (Ubuntu based) . The kernel is updated to 5.19.3 and various other adapters using mt7612u, mt7610u and various Realtel chipsets are all working fine.

Thinks to look at:

You thoughts and test results are welcome.

Follow on to my above message about the COMFAST CF-951AX: (using kernel 5.19.3)

Further testing this morning:

Regarding the bluetooth issue: Let me write out in simple terms what I think is happening:

I have tested multiple times with this adaper in a port and without it in a port. This adapter is causing the system to think it has bluetooth support. When the bluetooth firmware is available, it is loaded and then there is a failure noted in the log that makes it look like the driver cannot find the bluetooth hardware. If I remove the bluetooth firmware, firmware loading fails as expected.

So, it appears that ID 0e8d:7961 MediaTek Inc. Wireless_Device is triggering bluetooth support but the actual bluetooth hardware is absent or not turned on in this implementation. This leaves a lot of nastiness in the system log. This needs to be addressed as my system shows active bluetooth support but then nothing works. I don't need bluetooth support and I was not expecting it in this adapter but we have a little mess on our hands.

I have a little laptop that has an internal card based on the mt7921. WiFi and bluetooth work great. It looks like someone involved in driver development forgot to account for situations where bluetooth is not implemented.

On to continue testing USB3.

Follow on to my above message about the COMFAST CF-951AX: (using kernel 5.19.3)

Further testing:

Regarding the USB3 issue:

Tested with OpenWRT 22.03 rc6 on a ZyXEL NBG6817 wifi router that has both USB3 and USB2 ports.

Totally non-functional on USB3. Functional in USB2.

Tested with Linux Mint 21 (based on Ubuntu 22.04) with kernel upgraded to 5.19.3.

Same as with the router. Totally non-functional on USB3. Functional in USB2.

So, same results with totally different platforms. I smell a problem with USB3 but it is not clear yet what the problem could be. If you have a cf-951ax or cf-953ax, can you please check your results when the adapter is in a USB3 port?

On to continue testing...

Hi @morrownr,

here are some answers to your questions, using Xubuntu 22.04 with iwd and kernel 5.19.3.

Is your system showing a Bluetooth adapter?

Yes, it does. Mine is now running on USB3 connected with 2m USB3.0 extension cable, I previously tested it only on USB2. My OpenWrt router does only have a USB2 port.

does the bluetooth adapter work?

No, it doesn't work for me after installing blueman and bluez (I removed Bluetooth things on this install). I get error messages like yours in dmesg:

I'm not seeing that, could be because of iwd.

Similar throughput as with USB2.

coudu commented 1 year ago

Hi all,

same here, I've tested mine on OpenWrt x86_64 master, AP mode, and so far results are not good at all. Configured on 5GHz ac it works well, even a bit faster than my mt7612u based Alpha Network sticks, but on 5GHz ax I have a very bad throughput (~ 33Mb/s) and random reboots...

Didn't have time to further look in logs but I think the driver and AP mode needs a bit more work. Didn't test on USB2, only USB3, but my x86 router has both so I'll give it a try to see if it's any better.

This is very much appreciated.

Yes, it does.

does the bluetooth adapter work?

No, it doesn't work for me after installing blueman and bluez (I removed Bluetooth things on this install). I get error messages like yours in dmesg:

I pulled an old bluetooth 4 nano adapter out and plugged it in. I then paired the system and my phone... bla bla bla...and everything works. Our testing and results seem to confirm that the device ID is triggering support for Bluetooth that does not exist. That needs to be fixed.

Invalid HE elem, Disable HE Anyone else seeing that?

I'm not seeing that, could be because of iwd.

Hmmm... is it time to point the finger at wpa_supplicant for this one?

Do you have good guide for replacing wpa_supplicant with iwd?

Some results running it on USB3 port (distance to router, Fritzbox 6660 cable -> 7m with two ceilings between):

Which of the 2 adapters do you have?

Have you tried all of your USB3 ports followed by a lsusb -t to see if you are consistently in USB3 mode?

Thanks again,

Nick

Something we need to keep in mind is that the driver in OpenWRT is not necessarily the same as the mainline driver. The OpenWRT driver could be behind on patches. Same results for AX here... bad bad bad.

Which adapter are your using? Mine is the cf-951ax.

While testing, can you see if 5 GHz DFS channels are working?

Looking at commits for both linux mainline and backported OpenWrt they seem to be quite on par but Openwrt's 5.10 kernel might cause issues...

Which adapter are your using? Mine is the cf-951ax.

Mine is cf-953ax

While testing, can you see if 5 GHz DFS channels are working?

No, only tested on low channels

Invalid HE elem, Disable HE Anyone else seeing that?

I'm not seeing that, could be because of iwd.

Hmmm... is it time to point the finger at wpa_supplicant for this one?

I meant it that way, that since the switch to iwd all network interface messages are missing from dmesg. The event could still occur. Although nothing like that is listed in the iwd log.

Do you have good guide for replacing wpa_supplicant with iwd?

I didn't find a complete guide only partial directions, but that is what I did (for Xubuntu 22.04):

Switch NetworkManager backend from wpa_supplicant to iwd

sudo apt install iwd

sudo systemctl enable iwd.service
sudo systemctl start iwd.service

Add iwd-config-path=auto and wifi.backend=iwd to config sudo nano /etc/NetworkManager/NetworkManager.conf

[main]
plugins=ifupdown,keyfile
iwd-config-path=auto

[ifupdown]
managed=false

[device]
wifi.scan-rand-mac-address=no
wifi.backend=iwd

Disable wpa_supplicant

sudo systemctl disable wpa_supplicant.service

or (but I used just the above)

sudo systemctl mask wpa_supplicant --now

Reboot system.

I didn't try to revert the procedure, so be warned. Do it on your own risk.

Which of the 2 adapters do you have?

It is the CF-953AX model.

Have you tried all of your USB3 ports followed by a lsusb -t to see if you are consistently in USB3 mode?

That mainboard has only 2 USB3 ports and both show 5000M connection speed when I switch ports.

bcdonadio commented 1 year ago

Suggestion: before I was rudely interrupted by a shit ton of work these last weeks, I was testing on my main big x86 with plenty of USB3.{0,1,2} ports and bandwidth, and then handing off the USB devices directly to QEMU/KVM/libvirt via IO-MMU with two x86 VMs running OpenWRT nightly. Maybe this can solve your bandwidth issues?

I didn't get up to the point of doing performance tests, but I left the adapters pinging each other for a while without any issues.

I couldn't however test 6E because the regdomain for Brazil is completely outdated, and the kernel get clues from every damn where of where it is, including other APs and even cellular broadcasts. I left the work at the state that I was preparing a kernel build with a modified regdb with the latest updated rules from the government.
