Solved Ethernet

1. Setting IP
2. Download intel iwlwifi firmware support linux

   • Download firmware:
     • The MSI PRO Z690-A WIFI DDR4’s wifi card suppose AX201, so download the AX201 firmware:

     • Notice, the MSI Pro Z690-A WIFI (DDR5) & Z690-A (DDR5)'s wifi card suppose AX210
     • The brainless methoed is download and install all Wi-Fi 6 firmware of AX210 AX201 AX200
3. Extract the iwlwifi-???.tgz and follow the step of README file in it.
   • open the terminal and copy firmware file into /lib/firmware
     E.g.:
