Have a AP that I built usinga RB433AH and a XR5 card, running ROS 5.14. It is configured to do WPA2 and AES encryption. I tried to use RTS/CTS on CPEs only and noted that I can't browse the internet when connected to a CPE if the RTS/CTS threshold is not set to the default of 2346 bytes. Shouldn't I be able to set this to a low number? I also noted that when set to a low number, for example 32, the CPEs don't associate. Pls advise.
