Decent USB wifi dongle?

I have tried a couple of cheap ones from ebay the best speed i get is 5mbps on speedtest while my iphone gets 6.6mbps.

I don't have any free slots for a pci card so needs to be USB.

Even if you got the same result as your iPhone, we’re talking circa 200K extra here. I would suggest something with an external antennae that you can move to get the best possible signal may improve things, but it depends where you position it and the quality/gain of the antennae. Before spending the money consider if it’s really worth it for such a minimal gain.

I took a punt on another ebay one after reading some reviews it was only 6 quid, i ordered it yesterday and it arrived today and OMG i am now getting 8mbs nearly double what i was getting before, youtube videos now load instantly in 1080p even when seeking it seeks instantly like i have the video downloaded on my HD, it's never done this before, i can't believe i have gone years with my old dongle!
