Rated 4.3 out of 5 by 8 reviewers.
Rated 2 out of 5 by Would not buy again Bought to add WiFi to my desktop as I was moving to a rented house where I couldn't run ethernet cables. Used with a Vodafone wireless ADSL/ router, I admit it's possible the vodafone box does not have the strongest transmitter, but the vodafone box works fine with all other wifi devices in the house, i.e. laptop, iphone 4 &5s Sony tablet.... but when used with this edimax adaptor I found the signal would regularly degrade to the point of disconnection, and made online gaming impossible. Essentially this USB adaptor looks like ok build quality and is tiny, but it just doesn't work long enough, I even tried putting it on a USB extension cable to perhaps pick up a better signal, but I found that even when I got a fairly strong signal there would still be periods when it just stopped communicating with the accesspoint for no apparrent reason. Went out and splashed some cash on homeplug connection instead.... It;s fairly cheap, it is tiny, it doesn't work.... 18 July 2015
Rated 4 out of 5 by Good value For the money you are getting pice of good equipment. Plug and play, the cd wilt drivers is included, and works fine at the first attempt. Compact size make live easier. 02 October 2014
Rated 5 out of 5 by Does exactly what it says it will! I bought this dongle so I could set up a wireless hotspot on my PC and it works flawlessly! I can connect my phone and it works fine! 11 September 2014
Rated 5 out of 5 by EDIMAX WI-FI GADGET Excellent little gadget. Find a USB2 slot, plug it in, give it a few minutes to find out where it is and off you go. Excellent speed performance for me. 04 January 2014
Rated 4 out of 5 by Simple and cheap I had to relocate my router, which made it impossible to continue with a wired network. Also one of the older laptops in the house was having issues connecting with the new router. So I now own three of these adapters. Pro: Simple - Plug in it, connect, and forget. Cons: Throughput - Slightly slower than other, more expensive, models. Not to be considered slow through, and not an issue for more as it means that a single client can't use the entire bandwidth of my fibre internet connection. Overall: A good choose for a home needing multiple connections, and only one IT bod. 30 November 2013
Rated 4 out of 5 by Small and does what it says on the tin. This unit is small , yet powerful . Easy to set up and use and does everything it's meant to do. 14 October 2013
Rated 5 out of 5 by Works perfectly... on all Windows machines I've tried This is an excellent solution if you can't get a network cable to a machine. Install the software from CD, then plug in the USB wireless adapter and off you go. 01 October 2013
Rated 5 out of 5 by Just what was needed Purchased to cut down on the cabling when relocating equipment. Excellent bit of kit! 26 August 2013
