Preview. I was having trouble with download speeds from Wi-Fi, and since my MacBook Air doesn't have an Ethernet port, I decided to give this device a try. This requires a download from the Cable Matters website, but everything went smoothly and the device turned green. I turned off Wi-Fi Air and download speeds immediately increased to 3x what I had previously experienced. I will update later if I run into any issues but this product works as described.
