This adapter is simple to install and rock solid. If you have a newer AC router, this is a great choice to upgrade your wireless network connection on a Windows PC without having to open the case of your computer. For laptops, it is almost a no-brainer.

The adapter is about the size of a deck of cards. It has little rabbit ears and a rubber base to keep it from sliding around. The included USB 3 cable is thick, but they all are.

This is only for Windows use - like a dodo bird, I tried to install this on my Mac - the lights didn't even light up. There is Mac love with this adapter.

I installed this on a newly upgraded Windows 7 computer that had a G wireless card (yes it is a slightly older computer build). Installation was pretty easy - plug the adapter into a USB3 port (it will work with USB2), Windows install will fail, simply box out of that window. Insert the mini-CD and run the setup program. If you do not have an optical drive or one that will hold a mini-CD, the drivers are easy to get at the TP-Link website. I chose to install the full driver and utility package (you could use Windows zero configuration and not bother with the utility). After the installation wizard finished, a fancy wireless network choice screen comes up.

Before you choose your network, it might be a good idea to disable your other wireless adapter if you are upgrading. Enter the password for your network, and you are now connected to the internet. Done and done - no reboot necessary.

This computer struggled forever with internet connectivity. It is in a fairly remote corner of the house and never ran much better than 8 Mbps. After installing the adapter, I now get full 30 Mbps - exactly what I get with a wired connection to my modem. The adapter works flawlessly and reliably.

This is a rock solid outstanding USB wireless adapter.
