# Bouygues Bbox login, restart, Wi-Fi and devices

The Bbox is the box Bouygues Telecom and B&You supply in France. Bouygues documents almost everything through its customer app, which opens the Bbox admin interface; on your home network you can also open it in a browser at `https://mabbox.bytel.fr`.

Bbox

Sign in

`mabbox.bytel.fr`

App

Bouygues Telecom customer app (iOS and Android), through **Gérer ma Bbox**

Password

Bouygues’s help pages don’t say where a factory admin password is printed. If you don’t know yours, use **mot de passe oublié ?** (forgotten password) on the sign-in page to set a new one. The Wi-Fi key is a different password, on the white label at the back or on the screen of a Bbox WiFi 6E, 7 or 7 XT.

Models

Bbox WiFi 7 XT, Bbox WiFi 7, Bbox WiFi 6E, Bbox WiFi 6

**Checked 1 November 2026.** Bbox WiFi 7 XT, Bbox WiFi 7, Bbox WiFi 6E and Bbox WiFi 6, with the admin interface as reached from the Bouygues Telecom app (menus as of 2026). Bouygues’s help is in French; labels are quoted in French with an English gloss.

## Sign in to the Bbox

1. Connect your Mac to the Bbox’s Wi-Fi network.
2. Open `https://mabbox.bytel.fr` in your browser.
3. Enter the admin interface password and click **Connexion** (Sign in).
4. In the app instead: tap your Bbox line, then **Ma Bbox › Gérer ma Bbox** (My Bbox › Manage my Bbox).
5. Tap **Accéder à mon interface admin** (Open my admin interface).

Forgotten the admin password? Click **mot de passe oublié ?** on the sign-in page. A message shows how long you have; follow the instructions for your model, choose a new password and click **APPLIQUER** (Apply).

## Restart it properly

Bouygues documents a restart from the app, and on models with a screen, from the screen when it shows an error.

1. In the app, tap your Bbox line, then **Ma Bbox › Gérer ma Bbox**.
2. Tap the name of your Bbox.
3. At the bottom of the screen, tap **Redémarrer ma Bbox** (Restart my Bbox).

The **Reset** button (red at the back, or underneath on some models) returns the Bbox to factory settings, not a restart. Turn on automatic backup first so your Wi-Fi name and password come back.

### From the Bbox screen

On a Bbox with a screen, error codes S3, S4 and C1 come with a **Redémarrer ma Bbox** option on the screen itself.

1. Read the error code on the Bbox screen.
2. For S3 (synchronisation under way), wait about 15 minutes first.
3. Select **Redémarrer ma Bbox** on the screen.

### Schedule a restart

Bouygues’s help pages document no scheduled restart. **Programmer des pauses WiFi** (Schedule Wi-Fi breaks) only switches Wi-Fi off at set times.

**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

Bouygues’s help pages document no manual update or version page. On a Bbox WiFi 6 or 6E with a screen, an icon shows while an update is downloading.

## See connected devices

1. In the app, tap your Bbox line, then **Ma Bbox › Gérer ma Bbox**.
2. Tap **X Appareils connectés** (X connected devices) to see each device on Wi-Fi or Ethernet.
3. Each entry shows whether the device is new and how long since it was last connected.
4. To block a device for good, use Wi-Fi access control under **Programmer des pauses WiFi** (Schedule Wi-Fi breaks).

**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

Bouygues’s help pages document no UPnP setting for the Bbox. Its documented security settings are the firewall, under the three-line menu › **Réglages avancés** (Advanced settings) › **Ajouter ou modifier les règles** (Add or edit rules).

## Prioritise calls and gaming

Bouygues’s help pages document no QoS or device-priority setting. The app can pause Wi-Fi for chosen devices at set times, which is the closest documented control.

**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

The Bbox chooses the best band (2.4, 5 or 6 GHz) for each device automatically. On the Bbox WiFi 7 XT, the screen also offers a separate “WiFi Plus” network for Wi-Fi 7 devices and a compatible network for older ones.

1. In the app, open **Gérer ma Bbox › Accéder à mon interface admin**.
2. Tap the second icon at the bottom, **Mes réglages Wi-Fi** (My Wi-Fi settings).
3. Tap **Unifier mon Wi-Fi** (Unify my Wi-Fi).
4. Tap **Voir les réglages avancés** (See advanced settings) and check the automatic selection switch is blue.

### Change the channel

Bouygues documents only the automatic band and channel selection, not how to pick a channel by hand.

### Older devices on a Bbox WiFi 7 XT

1. On the Bbox screen, under **Un appareil a du mal à se connecter** (A device has trouble connecting), choose **Suivre le pas-à-pas** (Follow the steps).
2. Tap **Commencer** (Start) and try to reconnect the device.
3. If it still fails, tap **Non**, then **Activer le Wi-Fi compatible** (Turn on compatible Wi-Fi).
4. Scan the QR code or type the password shown on the screen.

**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

Bouygues sells its own repeaters (Répéteur WiFi 7 XT, WiFi 7, Bbox WiFi 6 and WiFi 5). Devices already joined to the Bbox move to the repeater automatically.

1. Check the Bbox is online and on Wi-Fi; on a Bbox WiFi 7 XT the icons show at the top of the screen.
2. Place the repeater halfway between the Bbox and the area that needs coverage.
3. Plug it in and press its On/Off button. Wait for a steady green light.
4. Or plug it into an Ethernet wall socket to place it further away.

Steady red means move the repeater closer to the Bbox; steady orange means move it further away. Flashing blue means it must be paired by hand, as described in its guide.

**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

The Bbox WiFi 6, 6E and 7 have a separate guest network that can’t reach your own devices or data.

1. In the app, open **Gérer ma Bbox › Accéder à mon interface admin**.
2. Tap the **WiFi** icon.
3. Under **Wi-Fi invité** (Guest Wi-Fi), move the switch so it turns blue.
4. On a Bbox WiFi 7 XT, you can instead choose **Connecter un invité** (Connect a guest) on the screen; guests scan the QR code.

Depending on the model, you can limit guest access to 2 hours, a day, or chosen days.

**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

Bouygues’s help pages document no setting for the DNS servers the Bbox hands out. For the Bbox Pro Ultra, Bouygues says the DNS can’t be changed; it documents only a dynamic DNS client on the **DynDNS** tab. 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. On a Bbox with a screen, read any error code. S1 to S3 point to the fibre or its module, G1 and G2 to the 4G backup key.
2. On a Bbox WiFi 6 or 6E with a screen, a red access light means a fibre problem.
3. A fast-flashing red connection light means the box reaches the fibre terminal but gets no IP address.
4. On a Bbox WiFi 6 without a screen, the internet **@** and fibre lights are green when working and red when not.
5. If an error persists, use **Mon Assistant Bbox** in the Bouygues assistance site, which detects your equipment.

Bouygues’s help pages don’t describe a connection log or line-statistics page in the admin interface.

**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

**Where is the Bbox Wi-Fi password?**

On the white label at the back if you haven’t changed it, or on the screen of a Bbox WiFi 6E, 7 or 7 XT. The app shows it under **Gérer ma Bbox › Personnaliser mon WiFi**.

**My new Bbox doesn’t use the Wi-Fi name on its label. Why?**

With automatic backup on, an exchanged Bbox keeps the old box’s Wi-Fi name and password. To use the label instead, choose **Restauration d’usine › Réinitialiser** under **Réglages avancés › Sauvegarder et restauration**.

**Can I turn on UPnP on a Bbox?**

Bouygues’s help pages don’t document a UPnP setting, so this guide can’t give a path for it.

## 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.
