Works well in Mint

Plugged in, booted into Linux Mint and it was working straight away. It gives a solid, stable connection. Good value for money.

Works great

Plugged in, installed drivers from the CD that came in the box and connected to the router without a glitch. Running win 7 64bit.

Had a lot of problems with other devices and their drivers. So glad this one works.

Well Worth the price

I got this for my latest PC since my old Belkin wireless USB adapter kept causing fatal blue screen crashes in Windows 7 64-bit (despite being listed as compatible on the microsoft website and, me having the latest 64-bit drivers for it).

I decided to buy this adapter since other reviewers had mentioned it working well in 64-bit machines.

Delivery aside this dongle actually works brilliantly. Has no problems with other dongles being used near it and is very good quality, especially for the price. It even gives me better signal than my Belkin dongle did.

The only problem I have had is occasionally it finds my routers signal but cannot connect to the internet with it. After rebooting my router it always works again so it is probably my router, but to be fair the router is about 5 years old!

All in all great dongle. Highly recommend it.

good product

this is a great product for the price! pings are now a constant 2ms with no real fluctuation to worry about. Before with my Belkin b/g adapter I was experiencing a 1200ms pause every 15-20 pings and a lot more general ping latency.
I think this is almost certainly down to new features like CCA. I Nearly gave it 4* is because the quality is better but the range actually seems marginally less than the Belkin. Expectedly its not the best of antenna but at

Quick driver install and plugged it in for Win7-64bit and it's worked perfectly. Router is through a couple walls and quite far away but signal is very reliable and steady. Very pleased.

Highly recommended!

I just bought 2 of these, they are an absolute bargain and good quality. very slim, nest and tidy.

I am able to get same 11Mbps ADSL Broadband with them from my Sky Broadband Unlimited Router downstairs using 54g (...wot, no Wireless N, Sky?)as I can with standard wired LAN cables connected straight to the router, and I'm really happy.

No fuss install on Windows 7 64bit Home Premium using the supplied mini-CD driver disc, just insert the USB adapter into a USB2 socket, insert the CD and Windows 7 says that only the driver gets installed on Win 7 64bit version, not the utility which is no loss. Then connect to your WiFi in seconds, no reboot needed.

TIP! Look underneath the packaging in the box for a useful 2ft USB extension lead which you may miss if you don't look under the inner packaging.

Highly recommended!

After having some connection issues with my "Edimax EW-7727In PCI Card", I bought this as a replacement and it's halved my ping in all games I play and I haven't had any drop outs like I used to.

Works on W7 64x without any problems and is quite cheap compared to others. Would recommend *****
