No Signal on two of the four router bands

[sanxion]

I have a GT-AXE16000 router. It's only a year old. Recently I found out that there is almost no signal in 5GHz-2 and 6GHz bands. These bands appear on my phone (Xiaomi 13) if the phone is in contact with the router. If a I move away a little, they disappear.

I've tried resetting the firmware to factory settings and updating it to other standard versions and to Merlin. The result is the same in all cases.

The status LEDs on both bands light up, so I think the issue is related to the antenas and not to the ICs.

Any solutions or ideas?

Thanks in avance.

Firmware and version?

Currently, latest stock firmware.

Well, the router has another issue. Aura RGB is not working. Leds do not light up

Bad power supply or hardware failure. Investing in a new power supply may work but could be a waste of time and money.
