I'm having issues with my wifi connection on my desktop, I'm using an external usb wifi card (Wise Tiger USB 3.0) since my motherbaord doesn't have one and when doing speed tests it's only reading 5Mbps download but my normal 12Mbps upload. I tested all my devices, laptop, phone and tablet, and they all read from 140 up to 220Mbps. I messed around with my network settings and restarted my desktop a few times without any change. I also tested the wifi adapter with my laptop and it works fine but I plug it back into my desktop and nothing changes. Someome has any troubleshooting tips? Is my desktop bandwidth being limited?
