AT&T MF279 - Frequently Asked Questions

Frequently Asked Questions
What kind of phone do I need to work with the AT&T Wireless Internet device?
Most standard touch-tone phones may be used. Rotary phones are not supported.
Cordless phone systems provide the most exibility and allow you to easily place
additional handsets throughout your home. Cordless phone systems still need to be
plugged in to a power outlet. A standard corded phone can be used if you need only
one phone in your home.
During a power outage, a standard corded phone that doesn’t require electrical
power is required for service.
How do I install my AT&T Wireless Internet device?
Refer to pages 4-10 of this guide for the most common installation methods. Other
helpful information:
• Installation near a window or outer wall is strongly recommended to ensure the
strongest possible wireless signal in order to maximize voice/data performance.
• If the AT&T Wireless Internet device’s Signal Strength light does not display
high signal strength (three [3] to four [4] bars) or voice/data performance is
unacceptable, you may need to relocate the device to another part of the home
with a stronger wireless signal.
Will my AT&T Wireless Internet device work in areas with no or low wireless
signal strength?
A strong wireless signal (three [3] to four [4] bars) is recommended for optimal
performance. A moderate signal (one [1] to two [2] bars) may be sucient. If you do
not see green or blue bars, you may want to move the device to a dierent location.
Does the AT&T Wireless Internet device support both voice and data?
Yes, you can use your AT&T Wireless Internet device for both voice and data, as long
as you subscribe to AT&T Wireless Internet voice and data plans.
