5 GHz Wifi interface not recognized on Archer C60 V3 after flashing 24.10.0

Hello all!

After flashing Open WRT 24.10.0 on my Archer C60 V3, only my Wifi 2.4 GHz is working. My 5 GHz is listed as unrecognized. Any ideas?

Can I use LUCI and just flash it back using sysupgrade to the previous version, where everything was working fine?

Thank you!

You need previous configuration backup and downgrade resetting configuration (or much slower - back up now, downgrade with config reset, and unzip the backup file and type back all configuration via LuCI web)

I don't have back up, I have already deleted all the config from the interface.

Can I flash 23.05.05 from LUCI selecting to delete all the previous config files?

Yes, you can downgrade resetting configuration.
For simplest usage - edit both wifi radios with country code, set channels to auto, edit both openwrt AP-s with your security (do not lcick anything else around), save configs, check again if they look as intended, and enable both wifi AP-s.

Thank you guys for all the help.

I reset the router to the default configurations, and successfully downgraded to 23.05.05 using LUCI.

Everything is working fine now.
