Laptop internet/download speed is much faster than desktop internet/download speed

Need some help with this, I've been trying to download GTA V on my new PC, but download speeds have been incredibly slow, so I have tested by placing my laptop and desktop in the same place and running speedtest, and my laptop gets download speeds of around 17-18 mbps and an upload of 2.8 mbps, while my desktop only gets around 4-6 mbps and an upload of 2 mbps.

I've been wondering if the problem is with the wifi cards?
My laptop has the intel dual band wireless-ac 3165, but my desktop has a wise tiger adapter (https://www.amazon.ca/gp/product/B01M0Q51UI/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1)

Also ethernet is not an option for me.
 
Solution
If the adapter in plugged into an USB 2.0, that might explain the low speeds. The speed could also be affected by the HDD speed and age.
