Though detailed, your post is ambiguous.
I'm guessing that you wish to share your internet connection with your daughter via wireless.
I think 100 yards is beyond the actual range of most domestic wireless routers other than with clear line of sight reception and without interference. Regardless of the makers' claims the rule, as I recall, is 50 feet or thru three walls.
The fact that you've added some sort of booster might help -- and there are solutions using hi-gain (i.e. unidirectional) antennas.
Of course even with perfect reception there remain questions about whether you have disabled wireless security while setting up, whether you have tried various channels (the different frequencies these represent may affect reception in different environments), whether you have detected neighbouring wifi networks and selected a channel 5 stops from the strongest.
