This project can be dropped for the official driver

[hphilm]

Mediatek released the official driver with its firmware.

Firmware: https://lore.kernel.org/linux-wireless/20260219193751.5823-1-sean.wang@kernel.org/T/#u
Driver: https://lore.kernel.org/linux-wireless/20260219004007.19733-1-sean.wang@kernel.org/T/#t

I did a backport today
https://github.com/hmtheboy154/mt7902/tree/backport

some said that it works, but have some trouble with insmod & depmod, so I have to check Makefile later

[hphilm]

Well on my end it kinda works: AerynOS/recipes#1449

I tried the official driver and the wifi worked using the official WIFI firmware submission https://lore.kernel.org/linux-wireless/20260219193751.5823-1-sean.wang@kernel.org/

However, I didn't find any submission for the bluetooth firmware, and using the one from this repo ( https://github.com/OnlineLearningTutorials/mt7902_temp/blob/main/mt7902_firmware/BT_RAM_CODE_MT7902_1_1_hdr.bin ) did not work

If anyone is interested, here's how to use it with nix dyegoaurelio/nixconfig@4a3db0f

Bluetooth firmware can be found here: https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/commit/?id=df954d275a0797cf3c1d3fb0cbb4580419b44bb0

they just merged it into linux-firmware

@OnlineLearningTutorials I saw your reply here
https://lore.kernel.org/all/20260221133748.309045-1-kush.kulshrestha.5@gmail.com/

I made this patch and it already works on my backport driver, you can give it to them so they can add it in

@dubhater Can you help me test this driver to see if the USB ID that you give here works ?

I don't want to open the laptop again...

Thanks @hmtheboy154, but I have already submitted the patch https://lore.kernel.org/all/20260214082738.139047-1-kush.kulshrestha.5@gmail.com/

and here https://lore.kernel.org/all/CAGp9Lzoq3nZS8A9m=H9JJmiCv11bWDmoLXqBLCU-Qm80k7=R1Q@mail.gmail.com/ they replied that they will include these ids in the next version of the chip may be in chip version 2 we have more features.

I am successfully able to run new wifi driver, please tell me if you are successfully running latest driver. One issue I noticed that when we run this latest driver, the dmesg is flooded with these lines:

IPv6: MLD: clamping QRV from 1 to 2!
IPv6: MLD: clamping QRV from 1 to 2!
IPv6: MLD: clamping QRV from 1 to 2!

if anyone can identify the cause of this line to appear please reply me, as how we can stop this line to frequently fill the dmesg log.

Yours isn't applied on top of their Bluetooth changes though.

I'll check later, you can try mine in the meantime

@hmtheboy154's wifi backport works for me too but the connection seems to dip out from time to time and feels slow but it's fast when it works, like starting an old car engine,

IPv6: MLD: clamping QRV from 1 to 2!

Can't reproduce unfortunately.

@hmtheboy154 your bluetooth backport works as well, but maybe a couple of modules need mentioning to be blacklisted? (btusb and btmtk)
Thank you and @OnlineLearningTutorials for your amazing work btw!

idk but the moment btusb_mt7902 is being loaded, both btusb and btmtk will not load anymore
Makes me wonder if I should tell people to blacklist
