R7000 v1.0.5.48 breaks 5G in Operation Mode:Access Point

Updated firmware to latest version (R7000-V1.0.5.48_1.1.79) and the 5Ghz radio was no longer working for main and guest networks.  The 2.4 GHz radios seemed to still be working properly.  I did not spend the time to see why it wasn't broadcasting for a longer period of time by running Kismet with a WiFi card in monitor mode.  However, I have several devices that could no longer see anything in the 802.11ac / 5GHz spectrum that in my configuration, was normaly being broadcasted from the R7000 router which is running in AP mode.

 

On a hunch, as I was pretty sure the firmware upgrade broke the 5G radio, I then downgraded back to the firmware version I was running prior to upgrade (R7000_V1.0.4.30_1.1.67) and all was well again.   Again, I am running in Access Point mode so I am not sure if other modes have this same bug.  This was very frustrating, but I was glad I could roll back this update and regain my previous functionality despite not being able to keep current with the firmware.

  • After the factory reset, make sure to re-enter the setup parameters manually, do NOT restore from backup, that appears to be incompatible as well.
