Mods, you may move this as you see fit. I'm posting in networking & wireless because one of the most common questions asked seems to be "What wireless adapter can I get that will just work?" I've advocated two, TrendNet TEW-649UB (rtl8192SU chipset) and NetGear WNA1100 (Atheros 9271(?) chipset. I just received and can add another 'just works' adapter. DLink DWA-131. It appears to be a close relative of the TrendNet-TEW639UB and the same size, it protrudes 2-2.5 cm. from the USB socket. It's plug & play Ubuntu 11.04 and later. Earlier versions require a firmware download. Speed is N150.
