This was picked up to allow me to run a RaspBMC media centre in a room where I didn't have a wired network connection. I fully expected to have to spend ages working through various online guides pokliung around the depths of a command line.
However, I'm very happy to report that it worked perfectly with next to no intervention required. Powered Raspbewrry PI down, inserted the adapter in to one of the USB ports on the PI and powered it up. Went system settings in RaspBMC where the dongle had been detected, selected wireless mode and asked it to perform a scan. Selected my SSID from the list, entered the password and away we went.
I could spend ages benchmarking etc. but the bottom line is I can now stream a full 1080p movie to the PI with no problems whatsoever.
If it helps, I'm running the most recent build of RaspBMC though I understand some older versions need the Network Manager plug-in for RaspBMC to use this properly.
Not much else to report really - does exactly what I want with no fuss and for less than a tenner. Top marks.


However, in actual use there are certain issues that you need to be aware of before purchasing.
Firstly, this receiver suffers from particularly low gain. It picks up half the signal that my Toshiba Tecra laptop does with it's built in WiFi for instance. So, whilst my Tecra can happily stay connected to a signal in my office, a desktop system that I plugged this adaptor into, failed. Low signal recognition meant the connection was very slow and completely unreliable, with constant drop-outs. So unless you have five bars worth of signal everywhere you want to use this adaptor, I suggest you look elsewhere.
Secondly, I found installation and set-up of the driver utility on XP Pro to be a total nightmare. Two hours of struggling with it and trying to get the software to establish a connection with the wireless router were wasted and I gave up. I turned instead to Windows own management software which worked perfectly and without any hassle.
So in conclusion - this is small and neat but be wary if your Wi-Fi signal isn't always at full strength. And beware the bundled software, for XP Pro at least.
After trying this adaptor I have decided that unfortunately it does not fulfil my needs - it just can't pick up enough of the signal that it needs to. Instead I have purchased a high gain adaptor that is absolutely superb, gives me five times more signal and didn't cost much more either. I shall shortly be writing a review of it, and you can see it here:

When I first used the adapter, it worked perfectly, the router was right next to where I had built my rig and I was getting full speeds. The missus's laptop wifi card died a death so I let her have the dongle and plugged in my ethernet while I waited for another one of these dongles to arrive (as I was creating a home office in the front room away from the router and didn't want to trail 5e cables from room to room).
That's when my issues started. At first I thought it was my router's signal strength, as both my rig with one of these adapters and the missus's laptop could not connect in the front room (our router is in the back living room) or we believed we may have a wireless cold spot. A quick change to a different wireless channel rectified the issue slightly, though only if the receivers were positioned in a very particular place in our front room, meaning I had to trail USB extension cables about to the location. Then today I boot up to find my rig is struggling to connect to the network and when it does connect, no pages will load up and the connection to the network dies after 3 minutes.
I fire up the missus's laptop to check speedtest.net and her adapter connects to the network fine, but only posts a download speed of about 3Mbps from the front room. Once again I thought it was my router so changed the wireless channel and tried again - no difference. I decide to perform a final check and stick the Wifi on on my Galaxy Note 2 and my works laptop and run speedtest through them. Both connect instantaneously and report a download speed from the same location as my rigs WLAN adapter of 19 to 19.5Mbps out of my 20Mbps internet connection.
I am firmly under the impression now that these adapters are crap at range and it's not my router at all. You may wonder how far my router is in the back living room from the front office room and I can tell you the direct distance in a straight line is no more than 5 meters. Further to this, my phone and works laptop don't drop connection speeds no matter where they are in the front office and after trying (my neighbours looked at me funny for this) I can confirm my works laptop and phone still posts a download speed of around 13Mbps on WLAN on the other side of the street outside the front of the house.
They work perfectly if you're going to sit in the same room as your router to connect to your wireless network, but useless if you want to stay connected more than 4 meters away from it - I can't even say I just had a faulty unit as the problem occurrs on both we have bought.
Lesson learned: don't buy budget PC peripherals, they're cheap for a reason.

Note: One thing - if you have more than one wi-fi profile set up (e.g. I have two - mine and my parents' router), it won't change between them automatically when you change location. However, when I boot up the netbook, the Edimax window opens automatically and I just click on the 'Profile' tab, double-click the required profile, and it connects in about 3 seconds flat.


I bought three more for my other PCs and Raspberry PI.
After a few months the signal seemed to steadily weaken and the connection started dropping regularly, to the point that I had to go back to ethernet cables.
I replaced one of these with a more expensive PCIe wifi card, and the signal went from 1 bar / ~20mbps up to 4 / 216mbps, and it has never dropped since. Now I just need to replace the Edimax dongles on my other PCs with the same make of PCIe card (TP-LINK). My download speed (i.e. from internet) has increased noticeably since replacing the Edimax dongle too.
I also need to figure out what to use on my Raspberry PI, which has just arrived... plugging this dongle in causes it to lock up without even so much as a kernel panic.
Summary:
- Adaptor seems to age; its performace worsens with time until it becomes unusable.
- Works on Windows XP x64 and plays ok with x64 Ubuntu (although still suffers the pre-mentioned ageing), but doesn't work on Raspberry PI (without a lot of tweaking, and some custom drivers).
- Worked great initially, but now they just sit in a box of other crap/outdated components.


The device does need drivers loaded (even for Win 7) but there is a mini CD supplied. Run the setup package and the device started working.
Only glitch is that on battery power the PC went to sleep and when I woke it up the wifi was not working. Checking the utility supplied the "radio off" box had been checked and so unchecking it brought it all back to life again. So it would seem that somewhere something kindly turned off the device presumably to save power.
But I've not seen that behaviour since.

I loaded Ubuntu 16.04 on to an old laptop, a Dell Inspiron 1501 ( which previously had the disastrous Windows Vista !!) and I had problems connecting to the internet. Or to be accurate, I couldn't connect at all despite trying everything. It's possible that my wireless card isn't working, because it wasn't detected on a machine scan.
However I read that the easiest way was to cut the Gordian Knot and get a wireless dongle and connect via a USB port. The question was, which dongle to go for ? To be honest, the most attractive thing about the Edimax N150 was the price as well as the reviews which seemed favorable overall, so I took a punt.
I'm very glad I did. Connection was a breeze. I just plugged it into the USB port, detected the network, entered password and job done ! I didn't even need the CD rom. Because it is so small, you just leave it plugged into the machine and forget about it, unlike the old dongles which stuck out about 2 inches and had to be removed or risk being broken.
Highly recommended

I run Ubuntu and Vista on an HP laptop which had intermittent and crap wireless.
Vista- Attempting to install on Vista was just a waste of time (just like Vista itself, hence why Ubuntu is also on there!) I tried everything I could think of- installation always *appeared* to work, but never actually allowed the laptop to get a signal; on the next power-up it would report an error that I never found out how to resolve.
Ubuntu- Neither the installation CD nor Edimax.co.uk had any Linux drivers, but the Edimax.COM *does*. With the help of Ubuntu forums I got it installed and it works perfectly now. Notice that the Linux drivers are unsupported at the moment, so you have to rebuild them every time there's a major update. However if you run Linux you're probably used to having to do things like that anyway :-)
So anyway, it's the tiniest thing ever, perfect for use with a laptop. If it was a full or even half-length USB widget my wife would have snapped it off within minutes of starting to surf the web for shoes. But with this in its miniscule form, there's no worry there!
It's mainly used in the same room as the router, so the fact it gets full bars signal and connects at the router's maximum 54mbps isn't much of a surprise. We haven't had any problems with data dropouts or network disconnection, but then we're just using it for general surfing and nothing with high throughput.
Why more people don't make wireless dongles this tiny is beyond me- it's great. The trouble with the Vista drivers knocked it down a star. Linux will wrap the drivers up at some point I'm sure. Till then it's a minor inconvenience and overall I'm very happy.

I reinstalled my desktop's factory OS which happened to be the dreaded Windows Vista and - of course - I had problems. It would not initially grab the drivers and instead claimed it had "installed them" but that they were "malfunctioning". After using the disc that came with it I got the tool running and once it forced a connection it updated. Every time I came out of reboot or hybrid sleep it would disconnect and would require me to re-sign in. I worked around this eventually by plugging it in a different USB port, but this does not seem to be unique to this USB adapter.

Wireless will never be as stable as wired connection but this time running a cable wasn't an option and Power line adapters are more expensive and would use a lot of power when compared to Raspberry Pi's <5W.
Overall performance when streaming 1080p is smooth though there can be occasional hiccups more likely due to Raspberry Pi than the adapter. It does get surprisingly warm so it is likely that it uses a significant amount of power, something to consider if using less than 1A power supply and/or overclocking. Dongle does have a fairly bright blue activity light which is useful. If it's unwanted it can be covered up with some tape which is what I did.
Adapter is tiny as shown in the images. At the cost of £8 it is a good deal. Would definitely recommend to any Raspberry user if wired connection is not an option.

I haven't used at great distance as bought for use on a Media centre PC about 6 metres away from router with a brick wall with door between. I'm getting good 4-5 out of 5 bar signal from the rear of the PC in a cabinet. Speed test consistent with my laptop at same range for internet connection. I haven't push tested on network as I don't do media streaming but getting 50+ Mbps on my fibre broadband at this range.
Tiny adaptor so would be idea to upgrade a laptop or where you don't want a massive dongle hanging out. Speed is rated max at 150Mbps which should be fine for most folks but you may need to look at 300Mbps devices if you are serious about streaming HD content
Worth noting you'll need to download drivers if you want to use on a win 8/8.1 PC but packaging does alert you to this. I've knocked a star off for this as this may present a problem for some


I bought it initially as an adapter for my Raspberry Pi which I intended to be a machine for learning coding - however, soon enough I realised that RaspBMC is a fantastic media center on the RasPi and it got moved to the lounge and hardwired to the router. The adapter worked straight away with the RasPi though - never missed a beat and gave great reception.
It's current use is in my wife's Windows XP laptop (replacing the internal wifi adapter which was giving intermittent problems). It's an absolute godsend, the reception is amazing, and it only just sits proud of the laptop body thanks to it's tiny size.
Over the years, I've owned Wifi adapters from Belkin, Netgear, and Buffalo. This one beats them all though - it's smaller, performs better, works out of the box with anything I seem to plug it into, and it's about half the price of any other adapter I've ever bought. What more do you want?

Picked up the Wifi signal once but then immediately lost it.
Not sure if I have picked up a faulty one or if they are all same?

UPDATE: Foolishly, I did buy Edimax again. This time I bought the Mac version "EW-7711MAC AC450". I thought this would be well made, since it costs more. Nope. Made of very thin plastic and broke with fewer than ten insertions. Fortunately this one at least clicked back together. When will I learn not to buy from this company? Moreover, why do they make such rubbish?

This Edimax adapter is about as small as it's possible to get and it's hardly noticeable plugged into the USB port on the side of the laptop (sticks out about 5mm). So far, so good. BUT, the mini-CD with the installing software just won't play in the standard size built-in CD player. Very annoying but easily solved by just following the instructions for software installation as suggested by the Sony laptop (just press 'yes' when it asks if you want help installing software without a CD. It must automatically search the internet and find the right site for driver software).
The annoying little blue light on the black part of the 'dongle' also seems to stop flashing after a few hours but it might well start again when something is being downloaded. A bit of masking-tape might be required if the blue light continues to annoy.
Anyway, small niggles aside, this is a very useful thing for wi-fi connectivity and well worth paying the extra money for such a neat and small gadget.


I bought this because I took a new PC that had win 10 and downgraded to win 7 pro. The only way to get online is with this usb unit.
So glad it worked and can stay plugged in as it barely sticks out.

I followed the very basic quick instructions provided on the included piece of paper and the instructions listed on disk, plus I tried the automatic setup provided on the disk. None worked. Not even the software which was installed with the required driver(s) worked correctly. It failed to list any of the available networks and the 'rescan' button would not respond.
I then tried to do a manual setup via Device Manager within Windows XP and, although this worked to a point, the final outcome was a message saying, 'Limited Access Only' against my router. That was the best I could get!
Although this device is labelled 802.11n, it was supposed to be backward compatible with 802.11b and g systems.
What made it more annoying was the fact that a device, with similar specifications, borrowed from my son and costing half the price, worked perfectly without any setup required. The driver was already available on the laptop.
If I hadn't damaged the original packaging on opening, I would have returned the item for a refund. At least it was free postage.

Once connected I logged on Raspbian, followed the instruction on screen and once entered the WiFi password everything was done!
I connected the the USB adapter straight in one of the RPi ports but I’ve read reviews and people who had to plug it in a powered USB hub, I’ve noticed anyway that by plugging the adapter in a powered hub the wifi speed is slightly faster.
This adapter will make you happy if you’re looking for a cheap way if you want to connect your computer or raspberry Pi to you wifi network with, if you want to stream FullHD video then I suggest you get something faster like a 450 or 300 Mbps USB Adapter.
