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

Doesn't require any weird pro-grade server backplanes to connect, just a regular PCI Express slot If drivers are needed, they can be downloaded as a bundle beforehand and installed offline SFP+ ports accept a few varieties of transceiver, so you don't even need to replace your ethernet wiring to use this

Its an Intel NIC. that is a pro in itself. NICs are one area Intel does well. Most recent purchase is specifically for its chipset as I'm using it in a custom network appliance. This is my second time purchasing this model.

Had trouble with server 2008 enterprise seeing any of the onboard or cheap NICs lying around, so I picked one of these up. Typical intel, worked perfectly. Teaming was easy (had to borrow another card to test), and I can easily exceed 1GB with multiple machines using cheap NICs talking to it.
