Tutorials: Internet and Wi-Fi

Router, Wi-Fi password, slow or missing connection: finding where the problem is.

  1. How to change your Wi-Fi password

    You change the Wi-Fi password from the router's admin page, choose a suitable security mode and reconnect computers, phones and the other devices at home with the new password.

  2. How to find a saved Wi-Fi password and share it

    If a device is already connected to the Wi-Fi, you can read the password there: in Windows, on a Mac, on iPhone and on Android. And to let a guest use it, you often don't even need to read it out: a QR code or sharing between Apple devices is enough.

  3. How to log in to your router (and what not to touch)

    Find the router's address, open its admin page from the browser and log in with the right password. Then learn which settings you can change safely and which are best left as they are.

  4. How to set your default browser and make Google your search engine

    How to choose the browser that opens when you tap a link (on Windows, Mac, iPhone and Android) and how to search with Google in Chrome, Edge and Safari, or with the search engine you prefer.

  5. Slow internet: how to measure your speed and find out who is to blame

    Measure your connection speed with neutral tools, find out whether the slowdown comes from your home Wi-Fi or from the line and, if the line is below what was promised, get the Ne.Me.Sys. certificate that counts for complaints and contract termination.

  6. Wi-Fi connected but no internet: what to do

    Find out in two minutes whether the fault is in the device, the router or your provider's line, and try the right fixes on Windows, Mac, iPhone and Android, from the simplest to the most drastic.

  7. Wi-Fi that doesn't reach every room: causes and fixes

    Why Wi-Fi doesn't cover every room and how to fix it: router placement, the 2.4 and 5 GHz bands, extenders, mesh systems, powerline and wired access points.
