Configuring your BGW320

Changing your Wi-Fi Network Name and password
 

The BGW320 offered through Sonic as well as any other devices offered with the resold AT&T service lack access to the AT&T Smart Home Manager app and will need to be configured through the device itself. Which is thankfully fairly easy. The process is detailed as follows.

• Gather info:

  On the back of your BGW320 will be the log in details as shown below.

  
  You will want to make a note of the Wifi Network's name, the password, as well as the Device Access Code. It is recommended to take a photo with your phone of the back of the device to streamline entering the needed information.
   

• Connect to the router:

  From a device connected to the BGW320 through either Ethernet or Wifi open a browser such as Chrome, Firefox or Safari and navigate to 192.168.1.254 and hit enter
  
  This should take you to a page that looks as follows
  
   

• Navigate to Home Network:

  Click on the header Home Network and you'll be prompted for the Device Access Code which was found on the back of the device. Once on the Home Network page click on Wi-Fi and you'll see the following screen.
  
  From this screen you'll need to enter in your desired Network Name and next to Security change Default Password to Custom Password and enter your desired password. Navigate to the bottom of the page, hit save and relog into the Wifi with the new name and password.
  
   

How to configure your BGW320 to work with a 3rd party router.

   Follow steps 1 and 2 from above until you are here at the front page as below
   

2. Get to IP Passthrough configuration

   Navigate to Firewall and click on IP Passthrough
   
    

3. Configure IP Passthrough:

   Change Allocation Mode to Passthrough and DHCPS-fixed like so
   
   Select your router from the drop down menu for Passthrough Fixed MAC Address
   
   Hit Save and your router and the BGW320 will not fight over where traffic is to be routed.
