I've got a TP-Link Archer C60 v3. I installed OpenWrt 19.07.7
Everything was fine but the radio0 (Atheros QCA9886) stopped working (why?)
I searched the forum and there are many users with 5GHz problems with ath10k module.
the 5GHz channel is not seen by any of my devices (it worked at first)
As suggested, I set Country code to driver default, 00 world, US, ... no success
I tried different channels auto-36-40, (or even 149) with 20MHz or 40MHz width... no success
I changed the kmod-ath10k-ct & ath10k-firmware-qca9888-ct with the one not optimized by Candela Technologies. or the "-smallbuffers" version ... no success
Are there people with same difficulties and suggestions?
Thanks! Openwrt is great!
