Why is my MediaTek MT7902 (14c3:7902) Wi-Fi not working on Ubuntu 26.04 even tho...

Why is my MediaTek MT7902 (14c3:7902) Wi-Fi not working on Ubuntu 26.04 even though it’s detected but shows as UNCLAIMED?

I’m having a Wi-Fi issue on my ASUS Vivobook (X1504ZA) running Ubuntu 26.04 LTS. I don’t really know much about this kind of Linux/driver/network stuff, so I’ve been trying to figure it out step by step.

Hardware info

My Wi-Fi card shows up as:

  • MediaTek MT7902 802.11ax (Filogic 310)

  • PCI ID: 14c3:7902


What works

  • Internet works fine using USB tethering from my phone

  • System is updated (kernel: 7.0.0-22-generic)

  • Everything else on the system seems normal


What doesn’t work

  • No Wi-Fi option appears in network settings

  • nmcli shows no Wi-Fi device at all

  • The Wi-Fi hardware is detected by the system but marked as UNCLAIMED

  • The mt7921e driver loads, but it does not attach to this device


What I found (with help)

I honestly don’t know much about drivers or kernel stuff, so I used an AI assistant to help me troubleshoot step by step. We checked logs, drivers, and kernel modules together.

From what we found:

  • The Linux mt76 / mt792x drivers are installed

  • But they don’t seem to support my exact chip (14c3:7902)

  • So the system detects the hardware, but no driver actually connects to it


Current situation

It looks like the Wi-Fi chip is not supported (or not fully supported yet) in my current Linux setup.


Workaround

I’m currently just using USB tethering from my phone, which works fine for internet.


Why I’m posting

Since I don’t really understand this technical stuff deeply, I thought I’d ask here in case someone knows a fix, patch, or workaround for this specific Wi-Fi chip.

Any help would be really appreciated 🙏 Should i install windows now?
