Practically speaking, about 70 feet, about 130 with the repeater.

I know it touts absurd numbers like half a mile, but color me dubious. Maybe on the Great Salt Flats with a tail wind....

The standard is what the standard is -- nicer equipment might take you to the theoretical limit, but it cannot exceed the limit

 

I don't think you have a clue what your talking about.
I have a dir-625 dlink router connected with g to my laptop and i get 150 ft through a brick wall and some trees.

 

I have a clue or two--the typical indoor range for 802.11g is about 100 ft @ 54 Mbps and it trails off the farther you go...I am very happy you are get such a wonderful connection, but if you want a reliable full strength connection your real world distance should be less than 70 feet.

At 150 feet you are probably at about 50 percent signal strength with ocassional packet disruption--perhaps not enough to lose your signal, but enough for your signal to be erratic.

If you don't like my answer, kindly disregard it, but that doesn't change the fact that the standard is what it is. Better equipment might give you a stronger more reliable signal at a greater distance, but you can't ignore physics
