4. Push the ON/OFF button to the ON position. Look at the lights on the
front panel.
• The POWER light blinks while your P-660N-T1A starts up and
stays on once it is ready. The DSL light is on when the P-660N-T1A
has a DSL connection, and the WLAN light is on when the wireless
LAN is ready. The INTERNET light is on when you are able to
access the Internet and blinks when the P-660N-T1A is sending or
receiving data.
• The LAN light stays on if the LAN port is properly connected and
blinks when there is traffic.
If any of these lights are not on, check your connections and inspect your
cables for damage. If the lights are still off, contact your local vendor.
