W-lan Slowly do something?

So I got a TP-Link USB Wi-Fi stick some time ago, I'm sitting about 1.5 meters away from the router and it is very slow but in the Wi-Fi settings and on my cell phone and LapTop the Wi-Fi is good you believe it is due to my Wi-Fi stick if so what suggestions would you have if no what should I do according to your knowledge.

Moin, I would believe it is because of stick. Can't you put your PC with LAN on the down?

Under these conditions, you can assume that the stick is out of order. You can exchange it.

Stay healthy!
