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."

If your router's light turns red, don't worry. Internet connection is ok.

Thank you BS and gurus!

Asus RT-AC68U in router mode: Just updated from 61848, and on the bandwidth monitoring page, I’m missing the wan interface…
I did clear the browser cache too. I’ll try downgrading to see if it re-appears. I’ll post a follow up.


Edit
61848 still does not have the wan interface. Did this change??
