Preliminary operations

Whether you want to change the password to access the Fastweb modem or that of your Wi-Fi network, you must necessarily access the configuration panel the device in question.

Despite what you may think, it is a very simple operation: first, connect to the Wi-Fi network generated by the router (or use an Ethernet cable, which is even more effective and avoids possible communication problems), start the browser you use to browse online from your PC (or even from smartphones and tablets, if you have decided to operate in Wi-Fi and use a portable device to do everything), type the IP address of the router in the URL bar and from Enter, in order to display the configuration page of the same.

Generally, the default IP address of (almost) all Fastweb modems is; if, however, you have changed some network settings or the IP that I have reported to you does not work, you can easily find the information you are looking for, directly from the operating system you are using. Below I’ll explain how to do it.

  • Windows: open the Command Prompt from the Windows Accessories folder of the Start menu, type the command ipconfigin it and press the Enter key on the keyboard: the IP of the router is located at the word Gateway.
  • macOS: open Terminal calling it from the Mac’s Go> Utilities menu and type the command ipconfig getifaddr en1, if you are connected via Wi-Fi, or ipconfig getifaddr en0, if you are connected with an Ethernet cable. After pressing the Enter key on your keyboard, you will see the IP address of the router.
  • Android: open the Settings menu > Network and Internet> Wi-Fi of the operating system, tap the  button corresponding to the name of the wireless network to which you are connected and tap the Advanced item. The router’s IP address is specified under Gateway.
  • iOS / iPadOS: go to the Settings> Wi-Fi menu of the iPhone / iPad, tap the (i) button located next to the name of the wireless network you are using and locate the IP of the router from the next screen.

If you are unable to enter the Fastweb modem following the instructions I have given you in this section, I recommend that you read the specific guide I have dedicated to the topic (which I have just linked to you), in which I have explained everything to you in great detail. details.

How to change Fastweb modem password: NeXXt

The Fastweb NeXXt modem works in a slightly different way than previously seen: for a specific company choice, access to the router is not protected by a password, as the preferential access channel is through the MyFastweb app ( available on the Play Store, on the alternative markets for Android and on the iOS / iPadOS App Store ), in which you must log in with your personal credentials.

So, afterwards, if you don’t have the app in question, download it from the reference market of your device: just go to the appropriate section, press the Install / Get button and, if applicable, authorize the download by authenticating via facial recognition, fingerprint password or password of the configured account.

If you no longer remember your login details for the MyFastweb app, you can retrieve them by going to this page, clicking on the Recover button located in the MyFastweb, FastwebUP, App and WOW Space Password box and following the instructions displayed on the screen: simply enter the tax code / VAT number of the contract holder, the mobile phone number or the email address issued during the activation of the services and, after passing the captcha check, click on the Retrieve button to receive the data at one of the registered addresses.

Once logged in, tap on the ☰ button located at the top left, tap on the NeXXt item located in the menu that appears and then on the My NeXXt box, located on the next screen.

Now, tap on the item Network settings, tap on the Wi-Fi network option and locate the box relating to the wireless network for which you want to change the password (at 2.4 or 5 GHz); if the Merged Networks option is on, you will see a single pane instead. Finally, tap on the Password field, enter the new network key in it and press the Save settings button to change the network key.

If you need to change the guest network password, go to the Network Settings> Guest Network menu instead and press the button to generate a new password.

If you wish, you can also do the same operation via the browser, but I must warn you: the web interface, at the time of writing this guide, does not work correctly and could return errors regarding the security certificate in use.

To proceed anyway, open the navigation program or app you prefer, enter the address in the address bar and enter: if everything went well, the access request should be sent to the modem NeXXt. To authorize the login, you must then press, within a few seconds, the physical buttons Fastweb (the central one) and Alexa (representing a dot ) of the modem. The available options are the same views for the app.
