I have a Lenovo laptop purchased several years ago that has a poor wifi plus the built in ethernet is only 100mbps which I found was pretty standard with regular laptops unless you're willing to spend for a high end one. My internet provider gives me 600mb/s but I was only getting about 50mb/s with the built in ethernet and even less with the wifi. I purchased this adapter and right away I'm getting close to 400mb/s when plugged in directly to my router! This adapter is the solution I've been trying to find. Pros: -This was simple to set up on my Windows 10 laptop. -It was working right out of the box and I've had no issues with it. -Great price

This card compared to my integrated (Realtek NIC) is much faster according to speedtest.net. The Intel card can sustain 50mbps average compared to the Realtek at 30mbps, and thats just internet speeds. Overall PC transfers using this card in my server PC can stream HD content from one of my 8 HD TV tuners and also from 4gb of movies stored locally to 5 networked PC's in the home and not cause slowdowns.
