I was thinking of getting a more expensive Wi-Fi directional antenna but this works so well I don't see the need now. This works fine on Windows 7 Pro 64bit and Windows 10 Pro 64bit. I didn't even have to unplug the internal adapter. Most negative one-star reviews are outdated and therefore no longer valid. In fact, almost all of the old one star reviews I've read refer to the ***Edimax EW-7811UTC AC600 Dual Band USB Adapter***, NOT this antenna. Make it clear, Revain. Sloppy. The only ones that might be of use also apply to anyone who plugs and unplugs USB connectors frequently. USB connectors tend to loosen with repeated plugging/unplugging. Not to mention the CR^P that ends up in the laptop's USB ports. In short, the IT works great.
