I can not find 5Ghz WIFI at repeater mode

I want to use this router in repeater mode. So I tested this many times.

I can connect 2.4Ghz WIFI and it works well. But I can not find my 5Ghz WIFI at the list.

I reseted and updated firmware many times. But I can not still.

Is my hosting router’s setting wrong?

Please help me.

Channel 149 is not used in most countries for stationary Wi-Fi - that could cause the issue, since the router would not pick up channel 149.

I would recommend changing it to some other channel. Please make sure to enable “repeating DFS channels” on your repeater as well.
