FAQ
Fail to pair Wi-Fi devices with the eWeLink App

information, if you "disable" the location service, the device cannot be paired.
3. Make sure your Wi-Fi works on 2.4GHz band.
4. Make sure to enter the Wi-Fi SSID and password correctly without special characters.
Incorrect password is a common cause of pairing failure.
5. To ensure good signal transmission while pairing, please place the device close to the
router.
1. Make sure the networking is normal. Check the internet works well by connecting your
phone or PC. If fail to connect, please check the availability of the Internet connection.
2. Please check the maximum number of devices that can be connected to your router. If
your router has a low capacity and the number of devices connected to it exceeds the
maximum, remove some devices or use a higher-capacity router.
If the above methods cannot help to solve the problem, please submit your problem to
"Help & Feedback" on the eWeLink App.
1. Devices fail to connect to the router.
2. Entered the wrong Wi-Fi SSID and password.
3. .Wi-Fi SSID and password contain special characters, for example, our system can't
recognize Hebrew and Arabic characters, which causes Wi-Fi connections to fail.
4. Low capacity of the router.
5. Wi-Fi signal is weak. The router and the devices are too far apart, or there is an
obstacle between the router and the device, which prevents the signal from being
transmitted.
