I think you are just seeing the advertised speed of the Router. If you have one which did 5.3 Gbps it would probably show that speed and I have to assume that is for multiple connections. What actual speed a file will transfer with depends on several things so it is hard to use that number as a measure.
On my systems, one shows 392 Mbps and the other shows 867 Mbps on the 5 G connection. Both show 144 Mbps on the 2.4 GHz connection.
