Wireless MT7961 not recognized

Installing and Using OpenWrt
1

So everyone, I made sure to look at the forum before buying a wireless usb adapter. My choice was this one, which says MTK7921AU.

After I added to my raspberry pi 4. It didn't show up in the Network > Wireless.

when I run lsusb:

Bus 001 Device 004: ID 0e8d:7961 MediaTek Inc. Wireless_Device

Filtering dmesg by vendor

# dmesg | grep 0e8d

[    1.259889] usb 2-1: New USB device found, idVendor=0e8d, idProduct=7961, bcdDevice= 1.00
[ 1801.871697] usb 1-1.1: New USB device found, idVendor=0e8d, idProduct=7961, bcdDevice= 1.00
[ 2003.453632] usb 1-1.1: New USB device found, idVendor=0e8d, idProduct=7961, bcdDevice= 1.00

Packages installed:

kmod-mt76-connac
kmod-mt76-core
kmod-mt7921-common
kmod-mt7921-firmware
kmod-mt7921e
kmod-mt792x-common

I have no idea where to go from here. Should I just return it, or there's a way to make it work?

That needs btusb too.

kmod-bluetooth is installed, but nothing changed.

~# lsmod | grep bt

btintel                28672  1 btusb
btrtl                  16384  1 btusb
btusb                  40960  0

Anything wrt mt7 in the boot log (dmesg)

root@OpenWrt:~# dmesg | grep mt7
root@OpenWrt:~#

root@OpenWrt:~# dmesg | grep wrt
[ 0.000000] Linux version 5.15.150 (builder@buildhost) (aarch64-openwrt-linux-musl-gcc (OpenWrt GCC 12.3.0 r23809-234f1a2efa) 12.3.0, GNU ld (GNU Binutils) 2.40.0) #0 SMP Fri Mar 22 22:09:42 2024

not sure if I understood the wrt part, but the commands above returns nothing relevant.

Also try fedora or ubuntu if you have space to do so.

Fixed. I am not sure if the upgrade was the factor. At the beginning everything was the same and I kept installing all packages with mt79*. I think the one that made it work was kmod-mt7925u.
So I hope it helps somebody else.

Did you also manage to get WiFi 6E working? How exactly did you do it? Do you have any other tips for other MT7961 owners who find this topic via Google or a forum search?

Actually the driver that worked was another. Here is the output of the commend suggested:

driver: mt7921u
version: 6.6.73
firmware-version: ____010000-20231109190959
expansion-rom-version:
bus-info: 2-1:1.0
supports-statistics: yes
supports-test: no
supports-eeprom-access: no
supports-register-dump: no
supports-priv-flags: no

I am using 2.4 GHz because of compatibility with older devices.
I don't have much more to say, the device works as expected and the coverage seems good too.

OK, fair enough. I was hoping for some shared experience regarding the 6 GHz frequencies. Not much has been written on this topic so far.
