Server sounds really impressive until you realize that it's just a pcie x1 slot. On the other hand, pcie x1 slot. I put it in a half size slot because it makes me not have to fight with a video card. Points up. This won't be apparent to you unless your card has ports facing another way. Get this one and save yourself a headache you will wonder why you even have.

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
