If you are not using the usb 3 port it won't make a difference.Thanks, it looks like its fixed it although on the RT-AC5300 it's WIFI>Professional>2.4>Reducing USB 3.0 Interference.
I also read somewhere @RMerlin recommend this is switched to disabled hence why i never changed it.
It may be better just to keep it disabled to avoid interference and simply use the usb2.0 port.
