I am in a production environment with several vlan/wifi SSIDs. But my campus just went one-to-one with Chromebook devices and the production network that they are connected to, is the same vlan across the network. So we have 6 sites, all same Vlan. My question is will this cause a bottle neck? Before covid, we never had any issues. Today, first day back with all students having their own Chromebook so obviously double maybe triple typical device amount, that particular SSID took a drastic decrease in speed, sometimes not even auth to the network. It seemed to get stuck. Now we were able to narrow it down to that particular SSID/VLAN, by connecting the hung ones to hotspots and our guest network and normal network function was restored on those. Switch back to production and went back to be extremly laggy. It seems that DHCP has handed out over 7K IPs thus far and that is not all of them. Is that too much for one VLAN? My theory is that they are bottlenecking somewhere or taxing one resource due to too many devices but I am just not sure where. Any help or guidance on where to look will be extremely helpful.
We use a cisco WLC blade attached to our core in the MDF, and each site has a dist that is routing through this core at the MDF. We are also using cisco ASA
