Bests & Worsts Reviews from Amazon

I purchased this to use it with a desktop in the upstairs bedroom directly avove the room in which the router is placed.. We recently switched our service provider to and the connection speed of 50 Mbps. My laptop connects without any problems when in upstairs bedroom with its built-in wifi and the speed I get is about 22 Mbps, when I take it downstairs in the same room as the router it jumps from 22 to 30Mbps, (45 Mbps via ethernet). I tried the Edimax with my laptop which has no problem connecting when downstairs but in the bedroom it keeps loosing the signal intermittently. My laptop has Windows 7 installed. I tried it with my second laptop which is an IBM Thinkpad with Ubuntu 12.04 installed. The speed I was getting downstairs was 12 Mbps which I thought was not bad but upstairs the speed dropped to barely 2 Mbps and sometimes no signal I decided to return it and selected another adapter TP-Link TL-WN722N which worked like a charm on all my machines. If you will be using the unit in the same room as the router be it Linux or Windows, this will work for you but if the router and the unit are at a distance, particularly on different floors you will have issues. The main reason for poor performance could be attributed to the unit being very tiny and the built-in antenna is not powerful enough for it to work at a fair distance from router particularly if there are walls and floors in the way.
