I bought this for a friend's old XP box and expected to have to struggle to get it to work - but all I had to to was plug it in and switch on!

Apart from adding a password, Windows configured everything automatically and it connected to the Sky Router (downstairs) at 300Mbps. Downloads and browsing the web are as quick as when using the previous hard-wired modem.

For the ease of use, performance and low price it certainly gets 5-stars from me.

I would note to anyone thinking of buying this product that the supplied CD doesn't contain drivers for Windows 7 or Windows 8. Windows 7/8 drivers are available on the Internet; I would advise downloading them before purchasing this product: http://www.realtek.com/downloads/downloadsView.aspx?Langid=1&PFid=48&Level=5&Conn=4&ProdID=229&DownTypeID=3&GetDown=false&Downloads=true#2291

Apart from the above, the product has been working very well for me so far and is well priced.

If your like me and sometimes find yourself struggling to get signal then this product is for you.
once you install the drivers from the cd your ready to go simply plug it in and your on your way to getting better signal and all you need to do is connect to the desired network and hey presto your internet ready.

The overall design and structure of this item makes this product ideal to use indoors and outdoors it can be mounted to a pole to allow longer reach.

overall this product is amazing and ideal for any traveller that needs to connect to the internet from anywhere.

A bit larger than I expected, but not that 'ugly'. The cable length is also good at a reasonable 5 metres. Very easy to set up, just make sure you install the software from the supplied disc before you plug it in to your PC. The range is decent, and it picks up quite a few signals from surrounding properties. Outside it is even better, but make sure it isn't raining, as it's not what you would call water resistant.

Overall, a good buy, and it has improved the strength of my internet connection massively. Recommended.

The Wi-Fi extender comes in a brown box with fairly minimal information on it. Inside we have a user and setup manual, the extender, a tripod mount wall mounting bracket, a device driver mini CD ROM, and a warranty card in Chinese.

Setting the extender up is extremely easy and you simply have to screw in the mount into the back of the extender and then you can plug the USB into your computer and then go through the setup process. Then you are able to get faster internet in the room as this helps to use your computer to act as a access point from which the extender will expand the Wi-Fi strength removing the need for a separate Wi-Fi extender.

The advantages of this is that you don’t have to separately power another extender and also it produces a much faster connection because of the fact that it is drawing connection from your computer rather than your router and because every computer has a more powerful internet modem inside than your router will have.

The build quality isn’t the highest for the stand and the actual broadcasting unit but the cable is braided and then it has an extra rubber sheath on top of it so it will be extremely durable and wont be damaged even if you put something ontop of it.

Overall this is a useful product for those who don’t want to use an extra power socket.

You would think the main reason why someone buys this product is to connect to the internet. The disc with the drivers on supplied was outdated (which is understandable) and didn't support the use of the adapter. So this then means you have to connect to the internet, to install the latest drivers so that it works. Although this isn't a huge problem for most people, as they will already have a computer connected to the internet. You can see why this would be a problem if it was someones first device connecting to the internet. In order to go online, I had to bridge the connection from my family laptop to my computer, to download the drivers that would make it work.

The disc isn't completely useless though! It comes with a program that allows you to go in advanced settings for your adapter and has 2 signal bars to give you more of a precise reading on your Wi-Fi signal.

Overall it's a great adapter, which gives you a great signal from your router, regardless where you are in your home. It comes with an antenna, which seems more like a aesthetic option than performance, as you seem to get the same amount of signal strength. Wouldn't recommend to someone who isn't confident on computers but it's pretty straightforward if you have a basic understanding.

I got a similar adapter myself, as our wifi isn't great. However, mine just plugged in and worked (Win10), but the missus' laptop was an issue, as she's got Win7 and a CD drive that stopped working a few years back. :)

Thanks to the answers and reviews here, this was the option we went for with her laptop, as links to download the drivers were supplied by users (thank you!).

She's seen no improvement in neither her connection nor internet speed. However, when looking at available networks, it's boosted several other wifi signals in the area! Ours continues to show as 3 bars on hers, whereas other's that only used to show as 1 bar, has now all jumped to three. We might just have to bite the bullet and also buy a booster to plug into a wall socket.

So it clearly works, just not the way we hoped for. Item seems just as sturdy as mine, which I paid over double the price for. We were probably just unlucky, due to our own Wifi, as if we'd been on one of the neighbouring wifi's it would have increased the signals with 2 bars.
