We're a decent size network with multiple VLANs. We have close to 200 projectors and about 10 of those projectors started having intermittent wireless issues. These 10 projectors connect wirelessly to their own wireless SSID, WPA2 encrypted network. Most of these projectors have been working for about a year.. something has changed on your network and now I'm having an issue with just a couple.
What would be the best way to troubleshoot this issue? Wireshark? Other thoughts?
We have all Cisco backbone, switches, WCS, WiSM, ACS.
Projectors are wirelessly connected to their own VLAN.
Projectors are set for DHCP
DHCP has correct reservations
Encrypt key, SSID info is correct on projectors
Two of are tech's can't figure it out and one contractor. Need the experts!!
