I recently acquired 10 CAP AC & a RB3011 to establish a WIFI network across my company, based on the capsman technology.
I have a big problem, and i already tried many things (such as playing with the rates, lowering Tx Power, Channel, only using WPA2 and AES CCM, 5Ghz band etc...), regularly the connection between computer and AP (NOT between AP & RB) began to slow down (Big & completely irregular latency from 50ms to 2000ms, random packet lost).
I already checked, it happens whether 10 computer are connected on 1 AP or just 1 or 2 devices an 1 AP, and with different type of computer & wifi cards.
We have two configuration for two SSID (corporate & public, and it happens on both.
AP & RB are up to date.
Have you got any ideas on what can cause such a situation?
