mt7902 driver development

As mediatek wifi mt7902 wifi 6E works fine in windows 11, however linux does not implemented its driver as it is new and mediatek does not respond to making a driver for linux. We try to take mediatek driver code in mt76 from kernel linux-6.8.9 and in mt76_new from kernel linux-6.11.0 from folder drivers/net/wireless/mediatek.

Compile and Build

Clone the repository to your local pc

git clone https://github.com/OnlineLearningTutorials/mt7902_temp

If you don't want to clone past history than

git clone --depth 1 https://github.com/OnlineLearningTutorials/mt7902_temp

If you want to build the whole module than you just open the terminal in the main folder and execute make it will compile all modules of mt76 project. however if you want to only compile the mt7902 than go to folder mt7902_temp/mt76/mt7902 and than execute the command make

Working with Kernel Modules in Linux

you can check currently loaded modules by lsmod. you can load a .ko kernel module by insmod. you can check if a module is already present in your kernel by modinfo. you can load already present module in kernel by modprobe. Insert the module in your kernel by

sudo modprobe mt76-connac-lib
sudo modprobe mt76
sudo modprobe mt76-sdio
sudo modprobe mt76-usb
sudo modprobe mt76x02-lib
sudo modprobe mt76x02-usb
sudo modprobe mt792x-lib
sudo modprobe mt792x-usb
