Xiaomi AX3200 - 5GHz Wi-Fi (radio1) suddenly stopped working / broadcasting

Installing and Using OpenWrt
1

Hi everyone,

I am having an issue with my Xiaomi AX3200 where the 5GHz Wi-Fi radio (radio1) has suddenly stopped working. It was working perfectly fine before, but now it refuses to broadcast, while the 2.4GHz band (radio0) still works completely normally.

Troubleshooting Output:

Any guidance on whether this resembles a known driver bug, a regulatory/DFS conflict, or a potential hardware failure would be greatly appreciated. If anyone has encountered this specific issue with the MediaTek mt7915 wireless driver on this hardware, please let me know your thoughts.

Thank You

Upgrade to 25.12 and see if still happens.

3

Unrelated, but sae-mixed is also a bad idea.

4

Are you attempting to configure the SSID for 2 networks?

If so, that's invalid.

5

Upgrade to 25.12 and see if still happens.

@castiel652 The official OpenWrt tables show that the current supported stable release is actually 24.10.5. Is it safe for me to upgrade to 24.10.5 instead

Unrelated, but sae-mixed is also a bad idea.

@frollic Ah, good to know. Is sae-mixed known to cause the exact issue I'm running into right now? What kind of problems does it usually cause on OpenWrt?

Are you attempting to configure the SSID for 2 networks?

If so, that's invalid.

Yes, I am. If that is invalid, what is the best practice for setting this up correctly?

6

It's outdated.

No, that's why I said it was unrelated, but it can cause issues with some clients.

7

Upgraded to latest version but still the issue persist.

OpenWrt 25.12.4 r32933-4ccb782af7 / LuCI (HEAD detached at e9ebca7) branch 26.133.20346~e9ebca7

What part of Xiaomi AX3200 - 5GHz Wi-Fi (radio1) suddenly stopped working / broadcasting - #4 by lleachii wasn't catched by you ?

Can you explain the goal of you adding two Layer 2 networks to one SSID?

What @lleachii said is correct. Option network must be a single network.

Set the country code on radio1 to MY. Both radios must be set to the same country. Confirm with iw reg get or iwinfo freqlist that the channel you are trying to use (36) is legal in MY. If it requires DFS the radio won't start immediately, so test with a non-DFS channel. Also try VHT20 instead of 80.

Read the system log for any wifi errors.
