How It Works

The AT&T Wireless Internet device uses the AT&T cellular network to provide phone service to your cordless or corded home phone(s) and Internet access to your computer and Wi-Fi enabled devices. Place it anywhere in your home where you have a strong wireless signal. It does not require the use of a home phone wall jack, unlike traditional home phone service.

The AT&T Wireless Internet device provides many calling services, such as Voicemail, Caller Number ID, Call Waiting, Call Forwarding, and Three-Way Calling, for your home phone(s). It also includes a backup battery in case of a power outage.

Device Installation

Before You Begin

The AT&T Wireless Internet device works exclusively with the AT&T

cellular network

and DOES NOT use your home phone wall jacks.

Your device should be located:

• Where you have a strong signal from a cell tower, typically near a window or outer wall. Signal strength may vary in dierent parts of your home.

• Near an electrical wall outlet.

• In the general area where you’ll be using your home phone, computer, or Wi-Fi enabled devices.

Select which phone and computer/Wi-Fi

enabled

device you will use with the

AT&T Wireless Internet device:

• A cordless phone system with multiple handsets should be used to place phones throughout your home.

• If using an existing phone, unplug it from the wall jack.

• For Internet access, you can simultaneously connect up to ten (10) devices per Wi-Fi network (2.4 GHz and 5 GHz), twenty (20) total, and one (1) via Ethernet.

ATT-WI-XXXX

Use the following information to connect

to the Internet:

STEP 1: Set Up Your Device

Install the Backup Battery

1. Remove the bottom of the device by pushing the entire cover in the direction of the arrow.

2. Insert the backup battery.

3. Replace the cover.

NOTES:

• The backup battery is intended for backup purposes only and may take

approximately three (3) hours to fully charge.

• Charge time may be impacted by environmental factors; the backup

battery will stop charging when the ambient temperature is outside of the temperature range allowed for charging: 32°F (0°C) - 131°F (55°C).

Ports

Battery

Check the Wireless Signal

Wait a few seconds for the Signal Strength light to turn on, while your device connects to the cellular network.

Conrm Signal Strength light has four (4) lit bars for optimal performance. Fewer bars indicate a moderate signal,

which may be sucient.

NOTE: If you do not see four (4) lit bars, you may want to choose another location in your home, such as near a window or outer wall.

STEP 1: Set Up Your Device (continued)

Turn On Your Device

1. Plug the power cord in to an electrical wall outlet.

2. Connect the other end of the power cord to the Power Input port on

the back of your AT&T Wireless Internet device.

STEP 2: Connect Your Phone

Unplug Your Phone From the Wall Jack

The AT&T Wireless Internet device is not used with your home phone wall jack.

NOTE: If you have a cordless phone, keep it plugged in to a power outlet.

Connect Your Phone to the Device

Plug your phone in to the “Phone” port on the AT&T Wireless Internet device, using your existing phone cable or the included phone cable.

NOTE: Do not plug the AT&T Wireless Internet device or your phones in to your wall jacks.

STEP 2: Connect Your Phone (continued)

Place a Test Call

Place a test call from your connected home phone. Make sure to dial the 10-digit phone number, including area code.

For best results, place the cordless phone base at least twelve (12) inches from the AT&T Wireless Internet device.

Important Phone Tips

• Voicemail is included with your service. Dial 1 to set up and access your voicemail. If you choose to use an answering machine instead, set it to fewer than four (4) rings.

• To place phones throughout your home, use a cordless phone system with multiple handsets. Wall jacks are not used with the AT&T Wireless Internet device.

• The second Phone port can be used to connect an additional phone or standalone

answering machine. It uses the same phone number as the rst Phone port.

• Your AT&T Wireless Internet device does not support incoming/outgoing fax service or home alarm systems.

• Your AT&T Wireless Internet device does not support rotary or pulse-dialing phones.

• Details on using voicemail and transferring a landline phone number can be found on pages 11-12.

There are two indications that a new message is waiting: 1) the Voicemail light and

The Voicemail light on your AT&T Wireless Internet device blinks green when a voicemail message is waiting. You will also hear an intermittent dial tone on any connected phone handset before placing a call.

Retrieving Messages

To retrieve voice messages, dial 1 on any home phone connected to the AT&T Wireless Internet device, and wait four (4) seconds to be connected to your AT&T wireless voicemail box. Simply follow the voice prompts to listen to and manage your messages. Alternatively, you may dial your 10-digit home phone number to access your voicemail box.
