AP has multiple SSIDs but randomly cannot connect to one SSID. The device is trying to negotiate and authenticate but cannot receive an IP address from the AP. This can cause due to DHCP pool of available IP addresses being exhausted and there are many conflicts. To resolve the issue:
- connect to the main switch at the site
- show run | section dhcp
- clear all conflicts: clear ip dhcp conflict *
- ip dhcp pool guest_wireless
- lease for 8 hours: lease 0 8
- end
- wr
- show interface counters errors
