I recently bought a fenvi 5400mbps adapter

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.

# 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

# 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.

5865 MHz [173] (20.0 dBm)

There are no 6 GHz channels listed.

What kernel are you using? 6 GHz was not added until kernel 5.8.

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.

lilkidsuave · Answer 9 · Sun Mar 24 2024 08:09:25 GMT+0800 (China Standard Time)

Did you even read the first comment.
The issue isn't that its blocked(its not).
The driver does not support the configured HE 6 GHz Max MPDU length

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 · Answer 13 · Mon Mar 25 2024 13:38:47 GMT+0800 (China Standard Time)

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.

Nick · Answer 14 · Mon Mar 25 2024 13:42:48 GMT+0800 (China Standard Time)

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.
