AT&T Gateway API

Python library for AT&T Fiber Gateways (BGW210, BGW320, CGW452).

Installation

pip install att-gateway-api

Or install from source:

pip install -e .

Usage

As a library

import asyncio
from att_gateway import ATTGatewayClient

async def main():
    async with ATTGatewayClient(
        host="192.168.1.254",  # or your gateway IP
        password="your-device-access-code",
    ) as client:
        # Get broadband statistics
        stats = await client.get_broadband_stats()
        print(f"Downstream: {stats.downstream.rate_mbps} Mbps")
        print(f"Upstream: {stats.upstream.rate_mbps} Mbps")
        print(f"Uptime: {stats.uptime_str}")

        # Get device info
        info = await client.get_device_info()
        print(f"Model: {info.model}")
        print(f"Firmware: {info.firmware_version}")

        # Get NAT table
        nat = await client.get_nat_table()
        print(f"NAT entries: {nat.count} / {nat.max_entries}")

asyncio.run(main())

CLI

# Test connection
att-gateway --host 192.168.1.254 test

# Get broadband stats
att-gateway --host 192.168.1.254 stats

# Get device info
att-gateway --host 192.168.1.254 info

# Get NAT table
att-gateway --host 192.168.1.254 nat

# Get raw HTML from any endpoint
att-gateway --host 192.168.1.254 raw broadband
att-gateway --host 192.168.1.254 raw /cgi-bin/custom.ha

Supported Gateways

Model	Type	Tested	Notes
BGW210-700	Fiber	Expected to work	Same firmware base
BGW320-500	Fiber	Expected to work	Same firmware base
BGW320-505	Fiber	Expected to work	Nokia hardware, Arris firmware
CGW452-400	5G Fiber	✅ Tested	Includes cellular/mobility status

All gateways use the same Arris-based web interface. The only model-specific feature is get_mobility_status() which is only available on 5G gateways (CGW452).

Authentication

The gateway uses nonce-based MD5 authentication. The password is the Device Access Code found on the back of your gateway.

Many status endpoints (broadband, fiber, devices) work without authentication. Configuration endpoints require the device access code.

Available Endpoints
