The Lesvieo 600Mbps USB WI-FI Adapter adds wi-fi capability to a device that does not already have it, extends wi-fi, or replaces a non-working connection. The package includes the adapter that you screw together, the CD with the driver/ manual, and the printed manual booklet.
The dual channel aspect is important as it supports both 2.4 GHz and 5.8 GHz. As most devices operate on 2.4 GHz, the band is saturated with traffic. Being able to access 5.8 GHz will result in a better connection and faster downloads. It is like traveling the high-occupancy travel lane or priority lane on a highway in the data sense.
You do need the capability of 802.11AC, which is the latest wi-fi technology to get the most of the adapter as far as range and speed. Lesser equipment will mean you can use this adapter still, but the performance will be commensurate with the capacity change.
My use of this dongle has been to extend the range of my wi-fi in my house and outside the house, where I sometimes like to work to get some fresh air and the sun. It is “plug and play” with Windows 10, which is what I use. I screw the two pieces together (it has a multi-angle rotation) and attach it to my laptop. That is it. Now my connection is good outdoors when it was spotty at best beforehand.
The wi-fi adapter has an 18-month warranty, so there is no risk. It also comes with lifetime technical support.
