I am currently using WPA2-Psk AES on our voice wifi which consists of 150 ap's, 2 wisms on 7.0.116 and 200 7925g's. Sine moving from firmware 1.3.3 we have been having dropped audio in 5-6 second bursts. I am just wondering how I can enable cckm without visiting each phone. I can't seem to wrap my head around it. Can I use cckm while still using a pass key?
