Setup

Attention⚠️, the ipk files in this repository only support official firmware. If you are compiling your own firmware, please refer to the scripts in the action.

First, download the corresponding ipk file according to your version, scp it to your device, and then run

opkg -i kmod-r8125_4.14.275+9.011.01-x86-0_x86_64.ipk

If you are using the 5.15 kernel, the r8196 driver should automatically drive your network card. If you want to force the use of the driver from this project, you can delete the r8196 driver.
