7762 poor/erratic performance for apartment buildings

unknown

We have several 7762s mounted in covered exterior hallways to service a couple of small apartment buildings.



What is the expected range through walls for the 7762s?



We are only seeing good signal and throughput through the first wall, but past the second wall signal and throughput drop fairly dramatically. Construction is standard stick-built.



RF pollution ranges from 50 - 150 and the estimated capacities on several of the APs is 5000 or less.



What kinds of things should we be looking at?
