Hello,
Archer C7 v2
OpenWrt 22.03.3
This is essentially a fault report rather than a problem.
I live in an apartment, with reasonable wireless channel density (radios above and below, not so much either side).
The Archer that I rescued from the trash was performing admirably for almost a year, when the 5 GHz AC radio seemed to drop out, the access point no longer being visible on any device. I run similar settings at 2.4 GHz, so I simply switched over to the lower band.
I assumed that if I powered off the router and re-connected it after 30 seconds, it might resume service on the higher band, but no. LuCI kept showing the QCA9880 radio operating at the mythical "? Mbit/s".
Then I searched and read another topic Wireless instability on ath10k radios after upgrade to 21.02.1, which suggested that the ath10k firmware and kernel driver were to blame.
So I have "rolled back" from the Candela Technologies firmware/driver to the original and rebooted, resulting in the restoration of my 5 GHz access point.
Is there a reason why the -ct variant is the current default for ath10k devices?
