DCN may assign an IP address to devices (computers, mobiles) connected to Wi-Fi AP associated with DCN enabled Enapter devices.
Solution:
- Delete the DCN from the Enapter Mobile App and create it one more time.
- If it is possible try to separate the DCN from your main network environment by connecting the DCN to another WiFi AP, no need to separate one DCN from another.
