Summary Clients are able to authenticate, authorize, and connect successfully. After connecting, they lose internet access. Things you can do Are all affected clients connected to the same AP when this happens, or is it random? Ensure the Meraki APs are running on a stable firmware version. When did this issue start? Have there been any recent changes on your side? Check the network path — confirm VLAN, STP, trunk/access, and other configurations are correct. Normally, an AP should not cause this since it only extends the wired network. Do wired clients also face this issue, or is ISE not used for wired clients? In summary: check firmware, roaming logs, event logs for clients and SSIDs, verify wired client behaviour, and inspect the physical network (cables, paths, etc.). With more details, we can narrow down the root cause. This is my understanding based on the given details.
