I'd recommend D-Link m8ty..
suppose you want a wireless access point? only 1 lappy, so no router function required..?
Have look HERE, found it HERE for 44notes, have shop around.
If you need to get a wireless card for your lappy, the DLink one is about 40notes (for the fastest, although you don't really need the fastest if all your doing is surfin' etc).
As for range, that really depends on your location, at home my access point is upstairs and get good signal strength all over house, have used friends lappy in garden no prob's, suppose thats about 30ish mtrs from access point..
