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

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.
