Zabovis Since Novice had a Baikal and you had a Belize, we decided to check the Baikal first. And, frankly @Dr4kk3N figured the firmware issue first for MT7668 chipset. Not undermining your work at all, but, you have to understand that the mainline kernel starting at 5.x+ have had support for MT7668's Bluetooth. The same cannot be said of the WiFi part, sadly. Anyways, for the WiFi to work with the method used, we had to use kernel 4.19. So, we could not use the usual fix for Bluetooth. We had to take another route for that too.
And, please do not feel left out. You worked hard to get the Bluetooth working on some other Belize models, and nobody's gonna take that away from you. But, WiFi requires another set of fixes altogether. In my article about the fix, I do mention and commend your efforts to help the community. So, thanks a lot for that. I request you to kindly not have any hard feelings regarding this. This is a huge success or atleast a small beginning for the whole community. I hope you will understand.
