Network consisting of 16 TP-Link switches and 50 access points suddenly lost connection, switches went to adopting state one by one with failover IP and were unable to reconnect until router and controller were restarted. Also in Wired networks under LAN tab, there was an error saying {LANNETWORK.NO_WAN_TIP} but the router showed connection to internet. Under statistics tab, on router there was a peak of 31 connected clients right before and during the loss of connection. Otherwise there were only 1 or 2 clients connected to the router. Clound and local management was working and controller was online.
Clients on router right before and during loss of connection - what could cause this?
