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.

Unable to access Wi-Fi network: how to fix

Have you carried out all the above checks but the wireless connection just doesn't want to work? Then carefully follow the instructions proposed in the following lines of this guide, valid for computers, smartphones and tablets.

Windows

If you can't connect to the internet and use a PC equipped with Windows 10, try starting it diagnostic tool included in the Microsoft operating system. To do this, right click on the button Home (the flag), select the item Settings from the menu displayed on the screen, then click on the icon for Rete and Internet and recati nella sezione State (located on the left sidebar).

Now, click on the option Network troubleshooting, choose the network card to diagnose (or leave the option selected All network cards, to perform a global check) and press the button NEXT, so that Windows can look at the status of your network and help you identify problems preventing you from accessing the Internet.

Now, press the button NEXT, wait a few seconds for the system status to be analyzed and start the Internet connection troubleshootingby clicking on the appropriate button.

In the unfortunate event that the Windows Diagnostic Tool fails to fix the problems that prevent you from accessing the Internet, try running a antivirus and antimalware scanning of your PC to find out if there are any viruses or malware blocking the connection. In my tutorials on how to eliminate viruses from your PC and how to eliminate malware you will find all the instructions - and programs - necessary to complete the two operations.

If the connectivity problems persist even after the antivirus and antimalware scan, I advise you to proceed with resetting the protocol Winsock and by resetting the DNS cache. To be able to do this, open the Command Prompt Windows by calling it from the folder Windows system / Accessories from the Start menu and issue, in order, the commands listed below, by pressing the key Submit keyboard each time.

Within a few seconds, macOS will let you know if something is wrong and will help you troubleshoot any problems with your internet connection. If no problems are found, you can start a network monitoring (putting the check mark next to the appropriate item) and get a more detailed report on the connection status.

Another attempt you can make to reset the internet connection on your Mac is to remove and re-add the network connection.
