That build is definitely unstable for my Linksys EA6400. After flash it from DD-WRT v3.0-r61745. Next step was r61848. Here the CTF module can't working correctly. The newest build provoke soft brick after rebuild iptables command via GUI. When I click save firewall button device made reboot. For more stable and tests I made reboot via SSH again. Router corrupt and totally stop respond. Hard reboot not solve problem and router can't start. Green led on case not working, boot wasn't correctly. I'm decide to restore by red button on case. Rollback to build 6/12/2025 and made fresh config.

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.
