Review: Dell 7020 - Windows 10 - The built-in network port on my computer failed so I purchased this unit. I plugged it into the PCI-e slot of the computer, turned it on, and it did not automatically find the new hardware. Turns out, that's what they want. The card came with a disk with a readme file stating that even if the computer finds the card, do not let it auto install. I ran the installation software and the card lit up. With this card, I am achieving 800+ Mbps download speeds. There are 2 network ports on this card, and there is a way to combine them in such a way to increase the speed, or redundancy of the connection. I'm not a gamer, so that was of no interest to me.
Review: Price - Needed for my failing computer. After installation the computer came back to life with internet.
