If you have any problem with adding your device to our App, please refer to the following steps to troubleshoot:1. Check whether your device is turned on.2. Ensure that the Wi-Fi network has a strong connection and stable signal. 3. If the network is normal, but the device network connection still fails, check if the router is overloaded. You can disconnect the device from the router to see if it has reached the upper limit.4. Check whether the router password you entered is correct. Look out for spaces before and after your Wi-Fi name or password.5. Ensure that your Wi-Fi broadcasting is enabled and that your device has been added to a Wi-Fi band of 2.4 GHz. (Check whether the 2.4 GHz band and 5GHz band share the same Wi-Fi account. If so, we recommend that you set up two accounts and switch to the 2.4 GHz band during network connection.)6. Confirm that the encryption method and authentication type are set to WPA2-PSK and AES, respectively, for the router’s wireless settings, or both are set to Auto.7. If wireless MAC address filtering is enabled for the router, remove your device from the router’s MAC address filtering list to ensure that you are able to connect to the network. You can also disable MAC address filtering entirely.8. Ensure that the DHCP service is enabled for the router. If not, the IP address will be occupied.If your device still fails to connect to the network after completing these steps, send an email to support@robertsmart.com and we will arrange for technical support engineers to troubleshoot this issue.
