Does anybody know of a USB 3 based wifi card that can do 1 gbps level speeds. 5.8Ghz preferably.

My old laptop's ethernet port broke and the internal wifi card is weak. It does like 40Mbps sitting next to the router.

Instead of wifi, I found this one: https://www.amazon.com/gp/product/B00BBD7NFU

Will try to see if it can be the replacement for my broken ethernet.
