Preliminary Operation

Let's start this guide by analyzing what may be the most common problems related to the failure of the Internet, attributable, for example, to an excessive distance from the home router or to the lack of credit on the mobile phone.

Wifi Connection

If your connectivity issues concern the home Internet connection (or the office), before going on try to follow these very simple tips.

  • Check that your modem / router is properly connected to the Internet. If the Fiber / ADSL connection light is not green and / or not solid, try restarting the device.
  • In the unfortunate event that even a restart of the modem / router does not solve the problem, make sure that the Internet connection cable is correctly inserted into the device (and that the wall socket is in good condition).
  • Try to contact your Internet provider (eg TIM, Vodafone, WINDTRE or Fastweb) and find out if there are problems on the line, or consult the DownDetector site to check for any global anomalies on the operator's network.
  • If the problem only concerns the Wi-Fi connection and only certain areas of the house, try to boost the Wi-Fi as I explained to you in my guide dedicated to the topic.
  • If the Internet connection is active but you are unable to view any Internet site, try to change the DNS of your connection by following the instructions in my guide dedicated to the topic.
  • Try connecting to the internet with another modem / router.

Cellular Network

If, on the other hand, your connectivity problems concern the cellular data network 3G, 4G / LTE or 5G, perform these other checks.

  • Check that the monthly traffic limit set by your data plan has not been exceeded: you can check the remaining Giga of your offer by following the instructions I have given you in this tutorial.
  • Check that your SIM has sufficient credit. If you don't know how to do it, feel free to consult my guides dedicated to credit verification TIM, Vodafone, WINDTRE, Iliad, Fastweb and PosteMobile.
  • Contact your operator and check if there are any faults in the network (generalized or concerning only your line). If you need a hand to contact the operators of TIM, Vodafone, WINDTRE, Iliad and Fastweb, consult my guides dedicated to the subject.
  • If you have just reloaded your credit, try restarting your smartphone / tablet and connecting to the internet again.
