- Restart your device, and then turn Wi-Fi off and then on again.
- Remove any protective case from your device to see if the Wi-Fi signal strength improves.
- Restart the router. Check that your router is Wi-Fi certified. Your device is Wi-Fi certified, so if the router isn’t, the devices may not communicate properly.
- Verify that you are in range of the Wi-Fi router. Check the Wi-Fi signal strength (Wi-Fi icon) in the status bar. If the signal is low, or there is no signal, move closer to the Wi-Fi hotspot, that is, the device that provides the Wi-Fi network.
- Make sure that the router is using the latest software version. Contact the router manufacturer for instructions on how to update the router software.
- Use a static IP address. Contact your internet service provider to ask about the IP address settings.
- Change the Wi-Fi network security of your router to a different security encryption. For instructions on how to change the network security, check the user guide of the router or contact your router manufacturer.
- Make sure that potentially interfering devices or appliances are not placed close to the Wi-Fi router.
Cordless phones, microwave ovens, baby monitors, wireless speakers, monitors and video transmitters that operate in the 2.4 GHz or 5 GHz bandwidth may interfere with a Wi-Fi network. If the problem persists, try changing the router frequency band settings to 5 GHz or 2.4 GHz.
For instructions on how to change router channel settings, check the user guide of the router or contact your router manufacturer.
- Perform a factory data reset. This is sometimes the best solution if your device stops functioning properly, but note that it will delete all personal content saved on the internal memory of your device. Make sure to back up data that you want to keep.
