# Fastweb NeXXt restart, Wi-Fi, guest network and port mapping

The NeXXt and NeXXt One are the modems Fastweb supplies with its home fibre plans in Italy, after the older FASTGate. Fastweb has you manage them in the MyFastweb app, or in the MyFastweb customer area in a browser, under **Gestisci NeXXt**.

Fastweb NeXXt

Sign in

The MyFastweb app or `www.fastweb.it/myfastweb`

App

MyFastweb (iOS and Android), or the MyFastweb customer area in a browser

Password

You sign in with your MyFastweb customer account, not a password on the modem. The Wi-Fi name and key are on the sticker under the modem and on the extra label in the box.

Models

Fastweb NeXXt, Fastweb NeXXt One, Fastweb Booster

**Checked 1 November 2026.** Fastweb NeXXt and NeXXt One through the MyFastweb app and customer area (menus as of 2026). The menus are in Italian; labels are given with an English gloss. The newer Modem Seven uses **Gestisci Seven** instead. Fastweb’s current help pages no longer cover the FASTGate.

## Sign in to the Fastweb NeXXt

1. Install the MyFastweb app and sign in with your Fastweb customer details.
2. On the home screen, tap **Gestisci NeXXt** (Manage NeXXt), or **Gestisci NeXXt One**.
3. Tap **La mia rete › Vai alle impostazioni** (My network › Go to settings).
4. Without the app, sign in to the MyFastweb customer area in a browser and choose **Gestisci NeXXt**.

Forgotten your MyFastweb password? Reset it at `fastweb.it/myfastweb/servizi/reset-password/`. The NeXXt also has a local configuration console, opened with a button combination, but Fastweb’s guides don’t give its address.

## Restart it properly

A restart keeps your Wi-Fi name, password and advanced settings. Phone, internet and Wi-Fi drop while it runs.

1. In MyFastweb, open **Gestisci NeXXt › La mia rete › Vai alle impostazioni**.
2. Open **Altre impostazioni › Reset impostazioni** (Other settings › Reset settings). In a browser it is under **Impostazioni avanzate** first.
3. Tap **Riavvia NeXXt** (Restart NeXXt).

**Ripristino dati** (Restore data) on the same page, or the RESET pinhole on the modem, returns it to factory settings and erases your setup.

### Without the app

1. Unplug the modem’s power cable.
2. Plug it back in after a few seconds.

### Schedule a restart

Fastweb’s guides document no scheduled restart. **Programmazione Wi-Fi** (Wi-Fi schedule) only switches Wi-Fi on and off.

**Kilobat can help.** Kilobat Pro’s [router check-up](https://kilobat.app/docs/home-network#router-checkup) learns how fast this router usually answers, says when a restart is due, and checks the next day whether it helped.

## Update the firmware

Fastweb’s guides document no manual firmware update. The NeXXt updates itself: its light flashes light blue during an update, and you must not switch it off.

## See connected devices

1. In MyFastweb, open **Gestisci NeXXt › La mia rete › Vai alle impostazioni**.
2. Tap **Mappa della rete** (Network map) to see the equipment in your home network and its signal quality.
3. For per-device access control, use **Altre impostazioni › MAC filter** and **aggiungi dispositivo** (add device).

Fastweb’s guides don’t describe a full list of connected devices.

**Kilobat can help.** Kilobat’s [new-device alerts](https://kilobat.app/docs/home-network#new-devices) tell you when a device you haven’t seen joins your home Wi-Fi. **Tools › Devices** lists what answers on the network, and you can name each one.

## UPnP and port forwarding

Fastweb’s guides document no UPnP IGD or NAT-PMP setting for automatic port forwarding. The **Dispositivi locali › USB/UPnP** page only shares USB drives and printers on your network. Forward ports by hand instead.

### Port mapping by hand

1. In MyFastweb, open **Gestisci NeXXt › La mia rete › Vai alle impostazioni › Altre impostazioni**.
2. Under **Internet**, open **Port Mapping** and add the ports and device.

An open port exposes that device to the internet. Forward only the ports an app needs, and remove rules you no longer use.

**Kilobat can help.** Without UPnP traffic counters, Kilobat’s [call reports](https://kilobat.app/video-calls) still name a busy app on your Mac or a Wi-Fi problem, but can’t point at another device at home.

## Prioritise calls and gaming

Fastweb’s guides document no QoS or device-priority setting for the NeXXt.

**Kilobat can help.** Run Kilobat’s [stutter test](https://kilobat.app/guides/recipes/test-call-stutter) before and after you change priorities, to see whether calls really got smoother.

## 2.4 and 5 GHz, and the channel

Fastweb recommends keeping 2.4 and 5 GHz joined as one network, and never switching 5 GHz off, because Boosters connect on it.

1. In MyFastweb, open **Gestisci NeXXt › La mia rete › Vai alle impostazioni › La mia rete**.
2. Choose to configure the 2.4 GHz and 5 GHz networks separately.
3. Give each band its own name (SSID) and password if you like.
4. Save, then reconnect your devices.

### Wi-Fi channel and mode

1. Open **Altre impostazioni › Rete Wi-Fi** (Wi-Fi network).
2. In **Broadcast SSID**, check the channel in use and the Wi-Fi mode.
3. If an older device can’t join, set **Modalità Wi-Fi** (Wi-Fi mode) to **Mixed 802.11a/n/ac**.

Fastweb advises keeping **Ricerca automatica** (automatic channel search) on, as set by default. Its guides don’t describe choosing a channel by hand.

**Kilobat can help.** Kilobat shows which band and channel your Mac is on, and `kilobat channels` suggests the least crowded channel. More in [crowded Wi-Fi channels](https://kilobat.app/guides/wifi-channel-congestion) and [Wi-Fi on a Mac](https://kilobat.app/wifi-analyzer-mac).

## Mesh: which node a device uses

Fastweb Boosters extend the NeXXt’s Wi-Fi and join its network automatically.

1. Connect your phone to the NeXXt’s Wi-Fi and open MyFastweb.
2. Go to **NeXXt › Estendi la tua rete › Installa** (Extend your network › Install).
3. Plug the Booster in halfway to the weak area and wait for its light to flash green.
4. Scan the QR code under the Booster. Steady white means a good link; flashing white means move it closer.

Without the app, press the Fastweb logo and Volume Up buttons for 3 seconds on the NeXXt, then on the Booster (WPS). A Booster can also connect by Ethernet cable.

**Kilobat can help.** When your Mac moves to another node or band, Kilobat’s Health says so, so a weaker node isn’t taken for a router problem. See [find a better Wi-Fi spot](https://kilobat.app/guides/recipes/find-better-wifi-spot).

## Guest network

1. In MyFastweb, open **Gestisci NeXXt › La mia rete › Vai alle impostazioni**.
2. Tap **Rete ospiti** (Guest network) and switch it on.
3. Set the guest network name (SSID) and password.
4. Save the change.

**Kilobat can help.** Kilobat can show a network as a QR code, so guests join with their phone’s camera: [share Wi-Fi with a QR code](https://kilobat.app/guides/recipes/share-wifi-qr-code).

## DNS settings

Fastweb’s guides document no setting for custom DNS servers on the NeXXt. Set DNS on the Mac instead.

**Kilobat can help.** Before you change DNS, [compare resolvers with Kilobat](https://kilobat.app/guides/recipes/pick-faster-dns) to see which answers fastest from your home.

## Connection status and logs

1. In MyFastweb, open **Gestisci NeXXt › La mia rete › Vai alle impostazioni** to monitor the connection.
2. From the home screen, tap **Speed test** to measure speed to the NeXXt and from the NeXXt to your device.
3. Under **Altre impostazioni › Internet**, set **Degrado della linea** (Line degradation) notifications.

A steady red light on the NeXXt means the line is down. Fastweb’s app has help under **Assistenza › Supporto Fastweb**.

**Kilobat can help.** When the line keeps dropping, Kilobat’s [provider report](https://kilobat.app/docs/health#report) lists outages, latency and speed tests against your plan, ready to send to your provider.

## Questions

**Can I manage the NeXXt without the MyFastweb app?**

Yes. Sign in to the MyFastweb customer area in a browser and choose **Gestisci NeXXt**; the menus match the app.

**Should I split the 2.4 and 5 GHz networks?**

Fastweb recommends keeping them joined for the most stable signal. Never switch off 5 GHz if you use Boosters.

## See what your router can’t tell you

Kilobat is a Mac menu-bar app that watches the network from your side: which app is using it, whether the Wi-Fi, the router or the provider is slow, and why a call froze.
