The Terrain, fres clearance, and antenna height are the limiting factors.

For 100mW, and 8dBi ; (my guess would be )

antenna lying on concrete floor, 50Metres max
antenna upright indoors - 200Metres (ish)
antenna mounted on roof - clear line-of-sight - 1KM (ish)
antenna  4metres above roof, house on hill,  flat grassy terrain, zero 
obstacles - range unknown, but *100% guaranteed* 1KM, and a lot of fun 
to had finding out..  8-))

Put a 15+dBi sector antenna on it, and go for a drive with a little dish 
and reeeeely have some fun.

disclaimer:  I'm a radio person, and a Linux person, but not (yet) a 
802.11 person.
