Restart your device and turn off Wi-Fi, then turn Wi-Fi on again. 

 

Remove any protective case from your device to see if the Wi-Fi signal strength improves.   

 

Check that the Wi-Fi sleep policy is set to always have Wi-Fi turned on.   

 

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 

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 both your device and the router are using the latest software versions.   

1.  Router: 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.   

To back up your data using a computer

C™ cable. 

2. 

Make sure that the USB connection mode on your device is set to Transfer files. 

3. 

Transfer/Save your important data in PC. 

4. 

Advisable to Sync your data in google account.

procedure.
