Unfortunately, this TP-Link device has not proved itself in my situation. I only wanted it and use it for the Wi-Fi extended part. I tested this device using Ookla Speed Test. So I ran the speed test 5 times in succession with and without the device attached. The average of 5 download speed test for using the device and not using were exactly the same speed. And I mean exactly the same speed! Not the most scientific of tests as your speed can vary widely during the course of day. But my testing was enough to show me that this device just didn't help me. Plus, over the few weeks I have owned this unit, I really didn't notice any difference in my Internet speed. Of course, it may vary for for others.
