So good I have 2

great card. both my pc's have them in!

Zero issues during either install on W7. Plug in, install via CD, then update driver manually. Perfect

Good (most of the time)

The first couple of months it performed perfectly, full signal fast speeds etc, but now it seems to be degrading - a couple of times a day it disconnects and cannot find any networks and I have to reboot my pc for it to start working again.

Greate card, set-up probs

After successfully running wireless on my PS3 and laptop on WEP without any hiccup, I was surprised at the hassle I had last night to get this card working.

After a few hours of hair pulling, I changed my router security settings from WEP to WPA2 and it connected straight away.

Now works perfectly; great signal.

Very Fast

Installed this with ease along with the driver and it took me no longer than 5 minutes.

Immediately I tried a download and found it capping at the max my internet speed allowed - all whilst streaming video and using a browser.

For the price you can't go wrong here.

Good card

Easy to install, good range and signal strength and a good wireless solution for a good price too.

True 300mbps

I had a Edimax EW-7727In nMax 300Mbps before this and would only work at 130mbps connected to my D-LINK DIR-685. Ordered this card for my brothers pc. Tested in mine and windows 7 picked up straight away and connected at 300mbps. So I'm very happy and the price cant be beat. A must buy in my books.

Doesn't seem too bad at all

Excellent price, quick and easy install, connected really quickly on Vista and fairly consistent connection, only dropped once in the past 24 hours and the PC tells me I have 2/5 signal strength.
Only thing is range- I have a small house, the router is downstairs and my computer is on the far side of the house upstairs, but still line-of-sight it is only about 2.5m away. Yes, the signal has to go 'through' the stairs and floor, then through my door but still I think it could be better.
I know my router signal is fairly good as I can use my laptop in the garden, but anyway if you are using this card in a nice open space with your router you won't have a problem. Furthermore, the connection speed is still a fast 54mbs (need to adjust my router to make it 120mbs) even with 2/5 signal strength.
All in all, a great product, thanks OCUK
