I got the AUKEY Wireless Adapter with USB 3.0 Speed up to 2.4GHz 300Mbps/5Ghz 867Mbps for Win XP/Vista/7/8/8.1/10, and just plugged it into my lenovo running the windows 10, and this small adapter helped my laptop run so much faster. My laptop is almost 2 years old, and I have had it in the shop twice and was getting a little up set with the speed of it. I had called my internet provider and they ran a check on my line and it was doing the speed it was suppose to. It was my laptop running slow so I thought well I'd give this adapter a try before another visit to the shop. This adapter runs the latest wireless standard which is 802.11AC, which allows for faster speeds and great range by simultaneously using both the 2.4Ghz and 5Ghz frequencies. With this adapter plugged into my laptop I can run max speed. I am so happy and please with this product and would recommend it to anyone needing a little more speed. I received this product free for my honest and unbiased review.
