There can be several reasons why your internet is not working. It could be due to issues with the device, problems with the carrier, Wi-Fi interference, your device is not connected to the router, or network congestion. To avoid internet connectivity issues:
Ensure your modem and router are properly connected and powered on. Check the antenna and make sure it is plugged properly and finger-tight.
Minimize Wi-Fi interference by placing your router in a central location, away from electronic devices or objects that may obstruct the signal. And, when finding better connectivity, we recommend you also test it on all four sides of your house power cycling the router each time you move its position. And, try to place it near the window.
Remember, internet connectivity issues can be caused by factors outside of our control, such as maintenance or network problems.
