The Signal Strength indicator on the AT&T Wireless Home Phone will indicate the quality of your wireless network signal:
A strong wireless signal (3-5 bars) is recommended for optimal performance. A moderate signal (1-2 bars) may be sufficient. If the AT&T Wireless Home Phone signal strength indicator does not display high signal strength (3-5 bars) or performance is unacceptable, you may need to relocate the device to another part of the home with a stronger wireless signal.
