after power is switched on.

The device encountered an

unexpected problem.

minutes, then reconnect the power and try the

upgrade process again.

Gateway to adjust its

performance depending on

the phone lines’

characteristics. The Gateway

may not have performed

calibration.

 Make sure an LAN cable is plugged into the port

marked LAN.



Unplug the telephone line. After the Gateway line

LED turns red, wait 15 to 30 seconds before

plugging the line back in.

The line is not in the correct

jack.



Make sure there is a line plugged into Line 4.

 Make sure an analog phone is plugged into the

Bypass jack (using a modular line cord).
