Optimize your networking experience – BGW210

Get the most out of your home network. Learn how to test and verify devices connected to your BGW210 are properly setup to connect at 802.11n speeds.

Modem / gateway






Set up your gateway for optimum performance

Establish baseline speeds

Running a speed test shows your baseline speeds, both wired and wireless.
Use the following steps to perform speed tests for your home network.

Wired speed test

Go to a computer that’s connected by wire to your Wi-Fi gateway.
  1. Close any other applications on your device.
  2. Shut down any other Wi-Fi enabled devices including tablets, smartphones, computers, game boxes, and DVRs.
  3. Run the AT&T Internet Speed Test from a desktop or laptop wired to your gateway to see download and upload speeds.

Wi-Fi speed test
Devices that use older standards like 802.11b or 802.11g won’t be capable of reaching the maximum wireless speeds supported by the BGW210. In addition, certain 802.11n devices only have a single antenna, limiting their throughput by half. Verify that your device is 802.11b/g/n/ac compatible by consulting the device's service manual or by visiting the manufacturer's website.

Prior to running a Wi-Fi test, disable all other household devices that may produce wireless interference. For example, Bluetooth devices, wireless phones, baby monitors and other wireless video devices.

This test should be performed with a clear line of sight and approximately 10 ft. away from the gateway.
  1. Connect to your Wi-Fi home network using your desktop or laptop.
  2. Close any other applications on your device.
  3. Shut down any other Internet-enabled and Wi-Fi devices including tablets, smartphones, computers, game boxes, and DVRs.
  4. Run the AT&T Internet Speed Test from a desktop or laptop connected through Wi-Fi to see download and upload speeds.

Performance figures will vary, and you should repeat this process with various wireless devices to rule out device-specific performance issues. Test only one device at a time, and if only one device has lower throughput, update that device's wireless adapter (if possible) and re-test.

Verify gateway settings

To verify your settings, follow these steps.
  1. Open a Chrome, Firefox, Internet Explorer, or other browser window.
  2. Enter to access the gateway settings screen.
  3. Select Home Network > Wi-Fi.
  4. In the Access Code field, enter the Device Access Code located on the side of your gateway.
  5. Verify the following for both radios:
    • Security is set to WPA. (Selecting No Privacy will also work, but is not recommended for security reasons.) Selecting WPA-PSK is recommended if the SSID is changed.
    • Mode is B/G/N. This standard allows the maximum interoperability with clients, while allowing 11n speeds (with the correct security).
    • Bandwidth is 20MHz.
    • Channel is set to Automatic (default setting).
    • Power Level is set to 100 for maximum coverage.

Gateway location and connections

Your home environment may affect performance negatively. For optimum performance, place your gateway:
  • Away from large metal objects such as metal racks and cabinets.
  • Not near other power sources. The power supply should be at least 6 ft. away.
  • Away from cordless phone bases or microwaves.
  • Standing vertical with nothing resting on or against it.
  • Not contained within a closed area such as a cabinet or closet.

Gateway connections
Direct wired connections provide the fastest speeds and free up Wi-Fi bandwidth. Try connecting devices you keep in one place, such as computers and game consoles, directly to your gateway using the available Ethernet ports.
