Hi I would like to know if I can use this antenna in my college across 2 to maybe 3 floors.
Yes, you do can use this antenna to receive the signal from 2 or 3 floors,
However I will suggest that you get this antenna to work with also the booster to get better preformance.
Becasue the wall will effect the wifi signal.
Thank you very much.
