When I check my client list in the Meraki Dashboard, I see a lot of devices in my network but most of them are in dormant mode, so they are using one IP from my pool, my lease is configured to 4 hours. The network is working as a guest network, where people comes to the local, connect to the WiFi of the business and leave, that's the reason because the devices remains in dormant mode, but looks like that Meraki doesn't release this devices and reserved it so in consecuence the network is insufficient.
