Table 157   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 the 

 chapter (web configurator) or the 

chapter (SMT).

Table 158   Troubleshooting the LAN Interface

I cannot access the 
Prestige from the 
LAN. 

If the 10M/100M LEDs on the front panel are both off, refer to the 

 section.

Make sure that the IP address and the subnet mask of the Prestige and your 
computer(s) are on the same subnet.

I cannot ping any 
computer on the LAN.

If the 10M/100M LEDs on the front panel are both off, refer to the 

 section.

Make sure that the IP address and the subnet mask of the Prestige and the 
computers are on the same subnet.

Table 159   Troubleshooting the WAN Interface

I cannot get a 
WAN IP address 
from the ISP.

The ISP provides the WAN IP address after authenticating you. Authentication 
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 the 

 chapter 

(web configurator) or the 

 chapter (SMT).
