# AT&T Fiber gateway (BGW320, BGW210) login, restart, port forwarding and Wi-Fi

The BGW320 (now called an All-Fi Hub) and the older BGW210 are the gateways AT&T supplies for AT&T Fiber and AT&T Internet. Everyday jobs live in the Smart Home Manager app; port forwarding and firewall settings are in the browser at 192.168.1.254.

AT&T Fiber Gateway

Sign in

`192.168.1.254`

App

AT&T Smart Home Manager (iOS, Android and on the web), signed in with your AT&T ID

Password

Pages that change settings ask for the **Device Access Code**, printed on the sticker on the side of the gateway. The Wi-Fi name and password are on the same sticker.

Models

BGW320, BGW210

**Checked 1 November 2026.** AT&T BGW320 and BGW210 gateways with the current Smart Home Manager app and web settings (menus as of 2026). Newer All-Fi Hubs (BGW620, BGW720) and older Pace and Motorola gateways use the same address but some menus differ.

## Sign in to the AT&T Fiber Gateway

The app uses your AT&T ID. In the browser, the gateway asks for the Device Access Code before settings pages.

1. Connect your Mac to the gateway’s Wi-Fi or plug it in with Ethernet.
2. Open `http://192.168.1.254` in a browser.
3. Choose a tab, such as **Home Network** or **Firewall**.
4. When asked, type the Device Access Code from the sticker.

AT&T warns that anyone on your network can use the default code, so you can change it in the gateway settings. If you forget a changed code, hold **Reset** for at least 15 seconds. That factory reset also erases your Wi-Fi name, password and other custom settings.

## Restart it properly

A restart disconnects every device. It can take up to five minutes to come back online.

1. Open the Smart Home Manager app.
2. Tap **Network** (the Wi-Fi icon).
3. Scroll to and tap **Restart Wi-Fi**.
4. Tap **Restart** again to confirm.

### Restart by hand

1. Unplug the power cord from the gateway and the wall.
2. If there’s an internal backup battery, remove it too.
3. Wait 20 seconds, refit the battery and plug the power back in.

Pressing the red **Reset** button for less than 15 seconds only restarts the gateway; 15 seconds or more resets it to factory settings.

### Schedule a restart

AT&T’s docs describe no scheduled restart.

**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

1. If you get a no-service error or a message to update, restart the gateway in Smart Home Manager.
2. AT&T says the restart gets the latest software version.
3. To see the installed version, tap **Network**, then your gateway, and scroll to **Device info**.

On a BGW320, a slowly blinking amber light means an update is installing. Wait until the light turns solid white.

## See connected devices

1. In the Smart Home Manager app, tap **Profiles & devices** and choose the middle icon.
2. Tap a device to see its details, rename it or add it to a profile.
3. On a computer, sign in to Smart Home Manager and choose **Network › Connected Devices**.
4. To cut a device off, open it and choose to block it from your network.

Only devices that are connected right now are listed. Devices the app can’t identify show as **Other** or **Unknown**.

**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

AT&T’s support articles for the BGW320 and BGW210 don’t mention UPnP at all. Port forwarding is done by hand on the **NAT/Gaming** page.

1. Open `http://192.168.1.254` and select the **Firewall** tab.
2. Enter the Device Access Code, then select **NAT/Gaming**.
3. Pick an application from the **Service** list, or create one under **Custom Services**.
4. Choose the device from **Needed by Device** and select **Add**.
5. Wait for it to appear under **Hosted Applications**, then select **Save**.

AT&T warns that port forwarding may let others reach devices in your home without your knowledge. It suggests one service entry per port rather than a range. IP Passthrough removes the gateway’s firewall protection from that one device.

### If you see a warning

On a BGW320, a warning on **NAT/Gaming** means port forwarding must first be enabled on your AT&T account. On a BGW210, AT&T says to restart the gateway, then try again.

### IP Passthrough for your own router

1. In the gateway settings, select **Firewall › IP Passthrough**.
2. Set **Allocation Mode** to **Passthrough** and **Passthrough Mode** to **DHCPS-fixed**.
3. Enter your router’s MAC address in **Passthrough Fixed MAC Address**.
4. Select **Save**, then **Restart Now**.

Your own router then gets the public IP address, and UPnP and port forwarding are handled there.

### NAT-PMP

AT&T’s docs don’t mention NAT-PMP.

**Kilobat can help.** On supported routers, Kilobat’s [call reports](https://kilobat.app/video-calls) can read available traffic counters, read-only, to identify another device that was busy when a call froze. Correlation does not prove the cause. Kilobat never opens ports.

## Prioritise calls and gaming

AT&T’s docs describe no QoS or device priority setting for the BGW320 or BGW210.

**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

AT&T recommends one Wi-Fi name and password for all radios, so the gateway can steer devices between bands.

1. In the Smart Home Manager app, scroll to the **My Wi-Fi** card.
2. Choose **Change** next to the name or password.
3. Enter the new details and select **Save**, then reconnect your devices.

### Find a clearer channel

1. In the Smart Home Manager app, tap the **Network** icon.
2. Swipe to and tap **Wi-Fi channel scan**.
3. Tap **Scan now**.

The scan shows which channel has the strongest signal and helps avoid interference. AT&T’s BGW320 and BGW210 articles don’t document setting a channel by hand.

### Per-band settings in the browser

1. Open `http://192.168.1.254` and select **Home Network › Wi-Fi**.
2. Enter the Device Access Code and select **Advanced Options**.
3. Edit the **2.4GHz Radio** and **5.0GHz Radio** sections, then select **Save**.

**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

AT&T’s AirTies 4971 Wi-Fi Extender works with the BGW320 and BGW210, provided both bands share one Wi-Fi name.

1. Open the Smart Home Manager app and tap **Network**.
2. Scroll to **Wi-Fi equipment** and select the card to add an extender, or tap **+**.
3. Follow the prompts to pair the extender.

On the web, sign in to Smart Home Manager and choose **Home Network Hardware › Add Wi-Fi extender**.

**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. From the Smart Home Manager main screen, tap **My Wi-Fi**.
2. Tap **Create guest Wi-Fi**.
3. Enter a guest Wi-Fi name and tap **Next**.
4. Enter a guest password and tap **Done**.

To share your main network instead, tap **My Wi-Fi › Share Wi-Fi** and send the details by text or email.

**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

AT&T documents no way to change the DNS servers the gateway hands out. Set DNS on the Mac instead, or put your own router behind the gateway with IP Passthrough.

**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. Check the front light; solid white means the gateway is online.
2. During an outage, open Smart Home Manager and tap **Learn more** on the outage card on the **Home** tab.
3. Without the app, check `att.com/outages` by ZIP code or after signing in.
4. To test speed, tap the **Network** icon, then **Speed test** and the start icon.

A slowly blinking red light on a BGW320 means no broadband connection. A solid blue light means it’s running on Internet Backup.

**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 Device Access Code?**

On the sticker on the side of the gateway, next to the Wi-Fi name and password. It’s needed only to change settings at 192.168.1.254.

**Why does NAT/Gaming show a warning?**

On a BGW320, port forwarding must be enabled on your AT&T account first. On a BGW210, AT&T suggests restarting the gateway and trying again.

**Can I change the Wi-Fi name in the app?**

Yes. In Smart Home Manager, choose **Change** on the **My Wi-Fi** card. You can also do it under **Home Network › Wi-Fi** in the browser.
