Media bridge mode at 5 GHz

[David Arnstein]

Summary: I cannot get media bridge working on a 5 GHz WiFi network. 2.4 GHz is OK.

Media bridge is RT-AC68P with Merlin firmware 384.19 and 386.1. Problem exists in both firmwares.

Upstream router is RT-AX86U with Asus firmware connected (wired) to a cable modem.

I have tried two different 5 GHz SSIDs. The RT-AC68P (Merlin) accepts the SSID and reboots. After that, wired client can connect to the RT-AC68P for a few seconds and then becomes disconnected from the internet; client's IP address is lost.

Two different 2.4 GHz SSIDs work OK.

Is this a known problem? Would it help to go back to Asus firmware on the RT-AC68P?

Hello L&LD,
If you are suggesting that I factory-reset my router, I did that many times. I mean, I held down the reset button for 10 seconds.

That isn't the recommended method anymore. Not even by Asus.

Try setting the 5Ghz to low fixed channel like 48 on the main router.
