Hello, I have a TP link T9E. Its currently connected to my universities internet on 5ghz and i only get 2/3 bars. How can i change to 2.4ghz? im presuming my laptop is getting better speeds as its got a better connection and its using 2.4ghz? i was hoping my pc would have roughly the same but its really bad compared to my laptop speeds, yet my laptop is really old. Thanks
