Wireless cards

Is there really any difference in performance between brands on laptop wireless cards or PCI cards for desktops?

The price range seems big - I can get a laptop card for £9.99ex VAT or pay well over £25. Do you get what you pay for or are they so simple they just do the same job?

Well, they're bound to vary to some extent in terms of quality and reliability, as with most things. Also open to variation is the connection protocol; most cards are for standard 802.11g plus the older 11a, but some cards are dedicated to certain "pre-n" standards, such as MIMO. Multi-in Multi-out works be splitting the signal across three or more aerials and bouncing each segment off surfaces. Other "pre-n" standards - and I use that word very loosely! - are boosted in some way. The forthcoming - a while away yet - 802.11n will run in the region of 108Mbits per sec, and the "pre-n" systems - which cannot be mixed - are designed to mimic this. 11g works at 54Mbits per sec.

"...plus the older 11a"

Whoops, major typo! Should have said 11b. 11a was different again.
