I am currently facing an issue with getting my MediaTek MT7902 802.11ax (Filogic 310) PCIe Wi-Fi adapter to work on my Arch Linux setup. I have already followed several troubleshooting steps, but I have not been able to get the Wi-Fi interface to appear or function correctly.
Here’s a summary of my setup and the steps I’ve taken so far:
System: Arch Linux, running GNOME.
Mainboard: ASUS X870 AYW Gaming WIFI W (with MediaTek MT7902 Wi-Fi adapter).
Wi-Fi adapter: MediaTek MT7902 (Filogic 310) PCIe.
Kernel: I'm running the latest stable kernel.
Network manager: NetworkManager is installed and running.
Steps taken:
1. I installed the mt76 and mt7921e drivers, which should support the MediaTek chipset.
2. The drivers load without error (lsmod | grep mt7921e shows mt7921e loaded).
3. I’ve tried modprobe mt7921e, modprobe mt76, and other related driver options.
4. ip link and nmcli device show no Wi-Fi interface (only enp7s0 and enp9s0u2).
5. I reinstalled the linux-firmware package to ensure all necessary firmware files are installed.
6. I ran dmesg and journalctl but couldn’t find any relevant errors related to the Wi-Fi adapter.
I’ve ensured that no rfkill block is active (rfkill list shows no blocks).
