Hello all,
I work at a school district, and at one campus we have a 3650 acting as a
wireless lan controller with 2702i access points. I've been contacted by
several teachers that are telling me that when the students are watching
videos on their Chromebooks, some of them will start randomly disconnecting
from wifi.
I've tested 11 Chromebooks in a room, and while watching a video the
channel utilization for both 802.11a and b will spike and some of them will
start disconnecting and reconnecting. I brought the same 11 Chromebooks
over to a different campus which has a 2504 wlc and a 3702i access point,
and I had no problem there. I brought the Chromebooks back to the
original room with the 3702 ap now being managed by the 3650 and had the
same issue. I even configured the 2702 and 3702 to be managed by the 2504
from the troubled classroom, and had no issue. This leads me to believe
that I have something misconfigured on the 3650. I have also tried
different WLANs, one 802.1x and one WPA2 with a psk, but the issue still
occurs.
I'm far from a wireless guru, so please let me know if you need help in understanding the situation better. Any
help will be greatly appreciated.
