Hi,
I flashed the C60 v3 with 24.10.
Did not find 5GHz WiFi only 2,4GHz
Is 5GHz not supported ?
If supported what can I do ?

Thanks

There is mentioning of C60 in the known issues, although your version is not specifically mentioned it could be affected ?
See: OpenWrt 24.10.0 - First Stable Release

You have to revert (sysupgrade) to 23.05.5, with config reset, then type back config from unzipped backup file.
