I have a resort with 16 access point going to the firewall and all of sudden anyone who tries to connect gets an ip address conflict and it bring down the network. I tried statically assigning IP address to access point then dynamically with no change. The IP scope is outside the range of anything that is statically assigned. I am assuming its a guests device that is causing the issue but how do I troubleshoot and even more importantly how do I resolve the issue since anyone staying here can access the wifi???
