# [Solved] PRO msi z690-a ddr4 wifi No WiFi and no ethernet on ubuntu 20.04
2022/04/18
## Description
Installed ubuntu 20.04 LTS desktop, but Wifi, BlueTooth and wired ethernet all wouldn’t’ work.

## Solved Ethernet
1. Setting IP
2. Download intel `iwlwifi` firmware support linux
* Download link: https://www.intel.com.tw/content/www/tw/zh/support/articles/000005511/wireless.html
* Download firmware:
* The `MSI PRO Z690-A WIFI DDR4`'s wifi card suppose [AX201](https://www.technextday.co.uk/product/msi-pro-z690-a-wifi-ddr4-12th-generation-intel-atx-motherboard), so download the AX201 firmware:
| Device | Kernels | Firmware |
| ------ | ------- | -------- |
| Intel® Wi-Fi 6 AX201 160MHz | 5.2+ | iwlwifi-Qu-48.13675109.0.tgz |
* Notice, the `MSI Pro Z690-A WIFI (DDR5) & Z690-A (DDR5)`'s wifi card suppose [AX210](https://www.anandtech.com/show/16970/the-intel-z690-motherboard-overview-over-50-new-models-with-ddr5-support/41)
* 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.:

        sudo cp iwlwifi-???.ucode /lib/firmware

4. reboot

reboot

5. The ethernet work~ but my wifi still not work...

6. If the method above no work, I had done the step below, I'm not sure which method make it work though.
* [Update Firmware on Ubuntu](https://itsfoss.com/update-firmware-ubuntu/)

        sudo apt update && sudo apt upgrade -y

        sudo service fwupd start

        sudo fwupdmgr refresh

        sudo fwupdmgr update

        reboot
