Internet stops working suddenly

Your Wi-Fi signal seems to be working fine, but when you try to connect to the network you notice that the internet connection has stopped working.

1. Cause: Internet issues in the router could cause such troubles. This might be indicated by the Internet LED on the router turning off or turning red, depending on the device you own. Your router might be assigned a dynamic IP address. If the network is overloaded or the router efficiency drops due to some reason, it might miss the communication of the new IP address, which can lead to internet failures.
2. Solution: Restarting the router will allow it to look for its newly assigned IP address. If the problem occurred due to a crowded network, taking this step should solve it.
