Table 76   Troubleshooting the DSL LED

The DSL LED is 

off.

Check the telephone wire and connections between the Prestige DSL port and the 

wall jack.

Make sure that the telephone company has checked your phone line and set it up 

for DSL service.

Reset your ADSL line to reinitialize your link to the DSLAM. For details, refer to 

 (web configurator) or

Table 78   Troubleshooting the WAN Interface

I cannot get a 

WAN IP address

may be through the user name and password, the MAC address or the host name.

The username and password apply to PPPoE and PPPoA encapsulation only. 

Make sure that you have entered the correct Service Type, User Name and 

Password (be sure to use the correct casing). Refer to 

 

(web configurator) or 

 (SMT).
