Summary: This USB Adapter was easy to set up and use. I already had a Panda Wireless 300Mbps Adapter and the Panda works about twice as fast as the Linksys and is cheaper. This Linksys is alright, but I would research a little further before purchasing another one like it.
Summary: As of July 24th 2015, the drivers for this are not in Windows 8.1 locally nor on Windows Update. You must use a CD drive or go on Linksys' web site to get the drivers. But the whole point of this device is your computer doesn't have an Ethernet jack.
