The camera has been set up wirelessly the first time but after several hours, it went offline and every time I access it, it says the network is busy. I tried resetting the device but it is no longer detected for set-up. I can hear the Du-Du sound, camera and my phone is connected to the same router but it is still undetected. I also tried adding by connecting a LAN cable but it is still undiscoverable. Please note that I also checked my router's properties. No DHCP or Port Filtering.
