The most likely situation is that if the mobile phone can connect to WiFi, but there is no network available, If there is a problem with the end connected to the broadband, you can unplug the network cable and plug it in again, or poke the restart button of the router with a needle. If that doesn't work, just cut off the power and restart it.
