Answer to "The wifi is not working and the led was not lightining"First of all check whether the WiFi button on the back side of your router is on or not? If not then switch on this button, after doing this. You can reset your device: 1) Turn off the device. 2) Use a pin to keep pressing the reset button for 15 seconds, and at the same time, power on the device. Now check again for WiFi networks, hopefully now you will get your WiFi issue resolved. But if you still not get your issue resolved then you can find a router helpline number of your router's brand where you can get your issue resolved.
