I want to buy a wifi USB adapter for my Ubuntu 10.04 computer, can someone recommend me on one that works out of the box?

The only adapter I have that works out of the box with 10.04 is a Trendnet TEW-424UB v3.1. It's an oldie but a goody for me. Downside is it's G speed, not N. Version matters with this adapter. There was a version 2.x years ago which used an SiS chipset and the only way to use it was with NDISwrapper. I have two adapters that run N150 but both require a tweak for Ubuntus <11.04. I've been happy with a Netgear WNA1100 but I used this installer from sourceforge for it:

I have a couple TrendNet TEW648UBs that work well with laptops due to their small size (and CompUSA had 'em for $14.99). They use RealTek 8192SU chips for which the firmware is missing in 10.04. The fix is pretty simple. Here's a link to the fix and firmware source:

Download the firmware file, place it in its proper place and restart. The blue light comes on and life is good until I suspend and resume. I had to unplug and replug in order to get it to work. Chili555 had the solution:

There may be other plug & play N speed adapters but I have no experience. I hope this is helpful in your decision making.
