I flashed the latest merlin into my RT-AC5300, maybe I did something wrong, the 5GHz-1 was gone.

The MAC address of 5GHz-1 is empty now.

I tried to set a MAC address with nvram set, then I can see the MAC address, but 5GHz-1 never up.

I tried to reset, I tried to change the SSID to 5GHz1 without dash, I tried to change it to none-AC mode, I tried to change channel, I tried 20/40/80Mhz, I tried to disable 2.4GHz and 5GHz-2, I tried to use the ASUS hard factory reset with WPS long pressing, I tried to flash back to official firmware, NOT WORKING :(

Something strange: when I disable 5GHz-1, the 5GHz-2 will have full speed in all channels, but if I enable 5GHz-1, the 5GHz-2 will be drop to 20Mhz.

Warranty expired, so any idea to fix it?

Have you gone to Wireless/Professional/and made sure that 5.1 is turned on. Had same issue and was headscratcher.
