To self-install AT&T Internet, unpack your official AT&T Self-Install Kit, connect the green broadband cable (for DSL/copper) or green-tipped fiber optic / red Ethernet cable (for Fiber) to your wall jack or Optical Network Terminal (ONT), plug in the power supply, and wait for the gateway LED to turn solid white or green. Complete activation using the AT&T Smart Home Manager App in approximately 15 to 30 minutes with $0 professional installation fees.
Self-installing your AT&T Internet service saves you the standard $99 professional technician dispatch fee and allows you to set up your home network on your own schedule.
Below is an itemized breakdown of what comes inside your AT&T self-installation kit, step-by-step instructions for both Fiber and Copper/DSL connections, activation guidance, and troubleshooting tips.

What’s Inside the AT&T Self-Install Kit?
When your self-installation kit arrives in the mail, verify that the following components are included:
AT&T Wi-Fi Gateway: The all-in-one modem and Wi-Fi router unit (e.g., BGW320 for Fiber or BGW210/NVG models for DSL).
Power Supply Cable: Two-piece power cord and AC wall adapter.
Green-Tipped Optical Cable (Fiber) or Red ONT Ethernet Cable: Connects the fiber wall plate/ONT directly to the gateway.
Green Broadband Data Cable (RJ-11): Used specifically for copper/DSL phone jack connections.
Yellow Ethernet Cable (RJ-45): Optional Cat6 cable for direct wired PC or gaming console setup.
Setup Guide & Wi-Fi Info Card: Contains your default network name (SSID) and Wi-Fi password.
Step-by-Step: How to Self-Install AT&T Fiber
If your home or apartment already has an AT&T Optical Network Terminal (ONT) or integrated AT&T Fiber wall jack installed:
Step 1: Locate Your Fiber Connection Point
Find the pre-installed AT&T Fiber wall jack (or standalone gray ONT box) inside your home—commonly located in the living room, home office, master closet, or utility area.
Step 2: Connect the Fiber Line to the Gateway
For Integrated Wall Plates (BGW320 Gateway): Remove the protective dust caps from both ends of the green-tipped optical cable. Insert one end firmly into the green AT&T Fiber wall port and the other end into the green optical port on the back of the BGW320 gateway until it clicks into place. (Do not touch the polished glass tip).
For External/Standalone ONT Boxes: Plug the provided red Ethernet cable into the active Ethernet/Data port on the ONT, then plug the other end into the red ONT / 5 Gbps WAN port on your AT&T Gateway.
Step 3: Power On the Gateway
Plug the power cord into the back of your AT&T Gateway and connect it directly to an unswitched electrical wall outlet. The indicator light will begin flashing white or green as it initializes (this boot cycle typically takes 5 to 10 minutes).
Step 4: Confirm Solid Status Light
Wait until the indicator light on the front panel turns solid white (or solid green on older models), indicating an authenticated, live network handshake.
3. Step-by-Step: How to Self-Install AT&T Copper / DSL Internet
If you subscribe to standard AT&T Internet delivered over copper phone wiring:
Connect the Green Cable: Plug one end of the green broadband RJ-11 cable into your home's active telephone wall jack.
Connect to Gateway: Plug the opposite end into the green Broadband port on the back of the gateway.
Power Up: Connect the power adapter to an electrical outlet and power on the unit.
Wait for Stabilization: Allow 5 to 10 minutes for the Broadband and Service LEDs to turn solid green.
How to Activate and Configure Your Network
Once your gateway status light stabilizes, finalize your account setup:
Download the App: Install the AT&T Smart Home Manager App (iOS or Android) on your smartphone.
Sign In: Log in using your AT&T User ID and password created during checkout.
Automated Registration: The app will automatically detect your connected gateway and complete registration on the network.
Personalize Your Wi-Fi: Update the factory SSID and password to your preferred custom home network credentials.
Run a Speed Test: Run the in-app speed test to verify that your download and upload bandwidth match your subscribed tier.
Common Self-Install Issues & Quick Troubleshooting
Gateway Light Flashes Red Continuously: The gateway is not receiving a broadband signal. Check that all cable ends are firmly seated. If the issue persists, the exterior street connection may not yet be activated by AT&T dispatch.
Slow Wi-Fi on Connected Devices: Ensure your gateway is placed in an elevated, central location away from dense concrete walls, metal appliances, and microwaves.
Activation Page Does Not Load: If setting up via a computer browser instead of the mobile app, visit [att.com/getstarted](https://att.com/getstarted) or 192.168.1.254 to trigger manual registration.
Frequently Asked Questions (FAQ)
Can I self-install AT&T Fiber if my home has never had fiber before?
No. If your home has never had AT&T Fiber installed, a certified technician must run a physical fiber drop cable from the street pole or underground junction to your home and install an Optical Network Terminal (ONT).
How much does AT&T self-installation cost?
AT&T self-installation is completely free. AT&T waives standard shipping charges for the equipment kit, saving you the $99 professional installation fee.
How long does it take for AT&T to activate my line after self-installing?
Once your hardware is plugged in and the gateway establishes a solid white/green light, digital activation through the Smart Home Manager app takes less than 5 minutes.
