Hi!
I’m trying to get Wi-Fi working on EndeavourOS with the onboard chipset of the Gigabyte X870 AORUS PRO, which uses the Qualcomm WCN7850 (ath12k / Wi-Fi 7).
System Information
- Motherboard: Gigabyte X870 AORUS PRO
- Chipset: Qualcomm WCN7850 (ath12k)
- Distribution: EndeavourOS (fully updated)
- Kernel: 6.15.3-arch1-1
- Firmware directory:
/lib/firmware/ath12k/WCN7850/hw2.0/
Files present: amss.bin, m3.bin, board-2.bin, Notice.txt
What I’ve tried
- Installed and tested:
- linux-firmware
- linux-firmware-qcom
- linux-firmware-atheros
- linux-firmware-git
- Also manually copied firmware from:
https://git.codelinaro.org/clo/ath-firmware/ath12k-firmware - Confirmed modules are loaded: ath12k, ath12k_pci
- BIOS Wi-Fi setting changed from Auto to Enabled
- Wi-Fi was working on the EndeavourOS live ISO, but not after install
