@garryf  I wonder if you and I have the same question. 

I am using an EAP225 outdoor AP on my house to provide signal to my outbuilding.  It works, but the signal inside the building is rather weak.  I'd love to put something on the outside of the building to 'catch' the signal from the AP on the house, then use a wire to 'rebroadcast' the signal inside the building.  I'm guessing another EAP225 on the outbuilding, but then not sure what I need on the inside...

@eric5899 I'd say it's about 150'  Works most of the time.  I think it depends on what other devices (family walking around with their phones) are traversing the area.
