As always, the Quantenna chip has its own quirks. This is a closed source chipset
There is no way to install a channel.
But you can disable 5.0 GHz. @mpgalaxy hack "If you set the radio mode to station bridge and disable the network mode, the 5GHz device will turn off completely even after reboot."

The fact is that the router is connected to the Internet (to the Internet provider). And it reports an error, the red WAN indicator flashes (the icon in the form of a planet). The internet works, I just think it's a glitch.
But this does not affect the work.
Just relax


1. Broken OpenVPN. Failed to start OpenVPN Client via configuration file. OpenVPN Status is empty. I don’t see this problem on the second router ASUS RT-N66U.

2. CPU temperature is not displayed correctly.
CPU temperature readings started changing after one second from 73.6 - 74.1 °C

Thank you BS and gurus!
