Bests & Worsts Reviews from Amazon

I bought this to increase the wifi signal (which is very weak, resulting in relatively slower DL's) for the second story of my home, because I read things like, "FASTER WIFI SPEEDS - Combined speeds up to 750 Mbps", and, "Mobile Up to 100% Faster Improve your mobile WiFi speeds by up to 100% with AC750 WiFi Range Extender!", - both are direct copy pastes from the Amazon sales page..... Unfortunately, on page 7 of the user manual, you find this gem: "Data traffic routed through the extender is inherently slower than traffic routed directly from the network." Speed test results (with Gigabit internet service): Regular WiFi: 279M down; 41M up. 2G extender: 156M down; 42M up. 5G extender: 122M down, 41M up. The range extender has a much stronger signal, but is close to half the speed! Total waste of money.
