and gone through the trouble of installing the drivers and setting the country code. The adapter works with AP mode well in 5GHZ, but gives me the following when I try 6GHZ.

# /etc/hostapd/hostapd-WiFi6E.conf
# Documentation: https://w1.fi/cgit/hostap/plain/hostapd/hostapd.conf
# 2024-02-28
# Status: rc3, please test and report.
# Note: This hostapd.conf file is for WiFi 6, not WiFi 6e (6 GHz).

# Purpose: hostapd.conf example for WiFi 6 configuration
# - specific to mt7921au chipset based USB WiFi adapters
# - tested on RasPi4B with 64 bit RasPiOS, 2023-12-05
# - see https://github.com/morrownr/USB-WiFi for...
#   -- make sure mt7921 firmware files are installed/updated in RasPiOS
#   -- you need hostap 2.10 or later for WiFi 6 support: $ hostapd -v
# - improvements are welcome

# Documentation: https://w1.fi/cgit/hostap/plain/hostapd/hostapd.conf
# 2024-02-28
# Status: rc3, please test and report.
# Note: This hostapd.conf file is for WiFi 6, not WiFi 6e (6 GHz).

# Purpose: hostapd.conf example for WiFi 6 configuration
# - specific to mt7921au chipset based USB WiFi adapters
# - tested on RasPi4B with 64 bit RasPiOS, 2023-12-05
# - see https://github.com/morrownr/USB-WiFi for...
#   -- make sure mt7921 firmware files are installed/updated in RasPiOS
#   -- you need hostap 2.10 or later for WiFi 6 support: $ hostapd -v
# - improvements are welcome

Hi @lilkidsuave

I would like to take a look at the driver you are using. Can you point me to it?

As you probably know, the example hostapd.conf that I have up for WiFi 6 is pretty solid. The one I have been working on for WiFi 6e is not solid and I have been busy on other things. WiFi 6e and 6 GHz gets a lot more complicated so this may take some time... or maybe someone a lot smarter than me has it all figured out and will stop by and help.

Hi @morrownr

Iw set country code doesnt work, so this is the way i made it US
lwfinger/rtw8852cu#2 (comment)
According to this forum post, the 8832cu is very similar to the 8852cu and the driver is the same.

EDIT: The wifi 6 config is pretty solid, just had to alter it slightly.

As far as I know, setting the country code to US ensures that the 6 GHz band is disabled.

The iw reg get says otherwise, and also I live in the us, so setting it to somewhere else could be illegal.

I have no explanation as to why your 6 GHz band is blocked other than something is wrong with your regulatory info. Is the package regd installed? That is what works with iw. The regualtory code in the vendor driver is difficult to follow. The standard Makefile sets the country code to XX and the channel plans to 0xFFFF. I have no idea what should be in the channel plans, but the country code should be changed there.

Did you even read the first comment.
The issue isn't that its blocked(its not).

I don't have a rtl8852/32cu based adapter so my ability to add anything to the conversation is limited. What I do know is that my experience working on the rtl8852/32bu driver left me feeling that Realtek does not seem to have a good dev working on their WiFi 6 drivers.

@lwfinger
Copy link

That statement is too general to be fair. The open-source Realtek developers work on PCI-based devices, which have good performance. None of that group works on USB devices. The only Realtek people that work on USB are the people that write the vendor drivers, which are mostly developed as a manufacturing aid. As long as the device works, that is sufficient.

You are correct. I should have been specific. Realtek's USB WiFi support is terrible.

It exists? A lot of sellers have you install their company drivers for realtek chipsets that aren't natively supported ootb.

@lilkidsuave
not that I'm an expert, but this is what I tried. you have 2 options.
let's assume your device is wlan5.

  1. work directly on the device (this will break existing connectivity), the device has to be brought down first, see below:
    iw dev wlan5 set 4addr on
    if there aren't any errors (such as Operation not supported (-95)), then it have worked
    finally, disable 4addr: iw dev wlan5 set 4addr off
  2. create a vritual device with the property set to on:
    first you have to take your device down
    sudo ip link set dev wlan5 down
    then you have to create a new virtual interface from it
    sudo iw dev wlan5interface add myNewIface type managed 4addr on
    then if you don't see any errors, bring it up
    sudo ip link set dev myNewIface up
    and finally delete it
    sudo ip link delete myNewIface

if the adapter you bought has support for it, I think I will buy it instead of the fenvi ax1800 I bought (#392 (comment))

You got an error of -95 because your device does not have a 6 GHz radio, i.e. you are asking for hardware that does not exist on your system.

First off - much appreciation to @morrownr for putting this together. There's not enough thanks for putting this site together and I've spent the last 4 days going deep into Realtek USB drivers for both the 2.5Gb LAN and Wireless. I always came back to your site to reference findings and try a different card. Ultimately I would like a 160mhz USB dongle for a 6ghz band that I have dedicated right over my head. Everything is at 40mhz across all other bands to keep reliability high for WiFI calling.

Then thank you @lwfinger for your dedication to the Linux kernel for the past 20 years. The open source space tests all of our patience to continue giving for free. I hope you're getting much needed vacation time in.

I have a variant of the card above; MSI AXE5400, and experience the same issues. I had to go one step further to add this to @lwfinger code in os_dep/linux/usb_intf.c from lwfinger/rtw8852cu

(USB_DEVICE_AND_INTERFACE_INFO(0x0db0, 0x991d, 0xff, 0xff, 0xff), driver_info = RTL8852C},

I had to also do a usb_modswitch and reseat after running the command:

usb_modeswitch -v 0bda -p 1a2b -V 0bda -P 1a2b -M 555342430860d9a9c0000000800006e0000000000000000000000000000000

After that I can connect to any 2.4ghz and 5ghz SSID but not any 6ghz SSIDs.

I know this device can do WiFi 6E @ 160mhz in Windows as I can see the full bandwidth after connecting to a 6E band.

Also I bought a AX3000M card that could not do 160mhz but could connect to WiFI 6E band at 80mhz in Linux.

I would surmise that @lwfinger 's driver has WiFi 6 support as I can see IEEE 802.11AX in my iwconfig list; however, I'm not sure if it supports channels and channel widths that the card can provide.

CONFIG_RTW_COUNTRY_CODE = US

Screenshot 2024-05-08 at 12 48 41 PM

This device kept switching back to 2.4/5ghz but I was able to lock this to my 6ghz radio with the wpa_supplicant having the following:

freq_list=5935 5955 5975 5995 6015 6035 6055 6075 6095 6115 6135 6155 6175 6195 6215 6235 6255 6275 6295 6315 6335 6355 6375 6395 6415 6435 6455 6475 6495 6515 6535 6555 6575 6595 6615 6635 6655 6675 6695 6715 6735 6755 6775 6795 6815 6835 6855 6875 6895 6915 6935 6955 6975 6995

I don't have an adapter with a rtl8852/32cu chipset yet but may have one in a few months based on the needs of someone I support. That would include me bringing the Realtek out-of-kernel driver up to speed for their needs. I generally also make the drivers public when I do that... so, my point is that I have little add right now for this specific chipset but my experience with the driver for the rtl8852/32au and bu has caused me to ask if Realtek even tests the drivers before shipping so...

...my advice, if you want something that is tri-band and you don't want to pull your hair out getting it to work, take a journey over to the Plug and Play List:

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

Go down to the section on the mt7921au chipset. Read, then look at the listed adapters. I have the Alfa AXML and the Edup adapter. If you are looking for something that is low cost, the Edup adapter is very good. Fenvi has an adapter that I have listed also. Even Netgear has the A8000 that works well but it is not cheap. All you have to do is plug the adapter in and go to work unless you are using a fairly old distro... needs kernel 5.19 or later.

If you want WiFi 7, I noticed this morning that cards with the new mt7925/27 chips are shipping which means usb adapters will be along soon enough. The driver has been in the kernel since kernel 6.7. The difference between Mediatek and Realtek usb driver support these days is astounding.

The situation is that the driver requires tweaking before 6 GHz will work correctly. I complete solution would be to interrogate regd to get the wireless rules, but I do not have a device, thus testing would be a problem. One could also create a module parameter file containing

options 8852cu rtw_country_code=US (or whatever country is appropriate)

The second problem of switching back to lower frequencies is because of roaming. Unfortunately, there is no switch to turn off roaming. If possible, you could give the 6 GHz band a different SSID.
