Hello, I have a RB433UAH with 3 R52Hn attached to it. I’m constantly adding new stations on it and now it seems that I’m getting so much interference that I can’t even ping those stations… One R52Hn has 63 stations connected to it, the other one has 52, and the last one has 17.
My question is: How many stations theses cards support without getting slow or getting interference?
You are close to the reasonable limits on the first two 
I suggest to adjust each AP frequency to be as far away from others as possible, and move all the antennas away from eachother.
I think that 50 stations per AP is reasonable amount.
How much bandwith do you provide for your customers ?
I believe he provides lots of timed outs 
Thank you guys for the replies… I had to add another router, card and antenna. Now its OK. Thank you very much!
