Hi chulk,

May I know what is your current firmware version? If the version is older than RT-AC55UHP_3.0.0.4_380_7378, try download the firmware below and try again.

Thank you

I am using the same router too... Let me test it tonight and see whether the same problem happens or not on my router... Will update later.

Hi chulk,

Thanks for the video, can you try do another factory reset on the router but this time using this combination.

Power off the router->press the WPS button and power on back the router(keep pressing the WPS button)->release the WPS button when you saw the power LED light start blinking very fast.

This will factory reset the router, try redo the setup again.

Is the second USB port also will have this problem too?

Hi chulk,

This might be hardware fault, do send the router for warranty claim.

Thank you
