Connect the Wireless Gateway | Gateway ATT110900764 specification

To replace an existing Wireless Gateway tethered to a Motorola modem, complete the steps in this guide. This guide assumes that you already have a properly installed modem from which you can access the Internet. Before beginning, power down and unplug the power cord from the electrical outlet for the Wireless Gateway. Then disconnect and save the power cord and all other cables connected to the existing Wireless Gateway. You will reuse these cables to install the new Gateway.

1Connect the Wireless Gateway

AA. Connect one end of the Ethernet Cable to the Gateway ‘Ethernet WAN’ port, and the other end of the cable to the ‘LAN Ethernet’ ports on the Motorola modem.

BB. Connect the second Ethernet Cable from the Gateway ‘Ethernet LAN’ port to the computer ‘Ethernet’ port.

CC. Connect the black Power Cord from the

Gateway ‘Power’ port to an electrical outlet.

2Power up

Configure Continued

F Click the Submit button. Wait approximately 60 seconds.

The Wireless Gateway now shares the WAN

IP address of the Motorola modem.

G At this point, verify in the Network Information page that the Motorola has issued the public/routable IP address to the Wireless Gateway. This step can be done in two ways:

a. The browser window tab should reflect the new IP address.

b. You can view the public/routable IP address from the Network Overview page, to which links are provided both from the Configuration Menu and the Network page.

AOn the modem, the Power, Internet and DSL lights should remain solid green. The Activity light may flicker and the Ethernet light will go dark until new Wireless Gateway is powered up and configured for the proper WAN interface.

BPower up your Wireless Gateway. During power up, it is normal for the DSL light to initially blink red and turn solid green, but as the Gateway proceeds through the synchronization process, it will ultimately blink green. Once complete, the Gateway will be configured for DSL, so the following LEDs should reflect a valid, accessible status:

• Power = green	• DSL Light = green blinking	• Corresponding Ethernet Switch Port for the
		laptop connection = green

Important: During this time, do not unplug the black Power Cords or either of the Ethernet LAN Cables, as this action can damage the modem and Gateway.

3Configure

To enable the Wireless Gateway to share the WAN IP address with the Motorola modem, you must configure the Gateway’s WAN interface settings to use DHCP. To configure the WAN interface settings of the Gateway, complete the following steps:

A Launch a Web browser on the computer that is connected to the Wireless Network Gateway and enter the following URL: http://192.168.2.1.

B The Gateway login prompt appears.

C Enter the following Login Information.

Name: custadmin

Password: admin

D Click the OK button.

The 250AEW customer administration Web configuration menu is displayed.

E In the left navigation pane of the Web configuration menu, select Network Overview.

Initially, the default setting is for ADSL WAN. You will set the WAN Interface settings to “Ethernet-DHCP.”

Shared WAN IP Address should be populated (not blank)

IMPORTANT: Wireless Gateway Automatic Upgrade Process

The Wireless Gateway is managed remotely by the AT&T Service Manager which is responsible for the remaining configuration steps. This step ALWAYS occurs after the Gateway shares the public IP address with the Motorola modem PRIOR TO MAKING ANY ADDITIONAL CONFIGURATION CHANGES, it is important that the device interacts successfully with Service Manager, and has auto-upgraded.

During the Service Manager auto upgrade you will see the following condition. The GUI screen becomes locked to configuration, and will only display an upgrade status. It is important to ensure that the device is not powered off at this time.

Download progress messages will be displayed as follows: “Writing upgrade is __ percent complete”. When the system reaches 100% the gateway will reboot automatically. At this point, close your browser and open a new browser session to the address 192.168.2.1.
