C5210 controllers with 9.21.10.5 and 3605/3610 APs. Does anyone else in a school district setting have roaming issues and ways to improve it? We have principals that use iObservation tool on their Macbooks and roam to different classrooms. They say they can connect, get kicked off, can't get back on, get dropped...Is there such a thing as seamless roaming? I tell them to reboot machine and turn wifi on/off.
