Chapter 11 Troubleshooting

Table 29   Troubleshooting the LAN Interface

I cannot access the 

Prestige from the 

LAN. 

If the LAN or PC LED is off, 

.

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 LAN and PC LEDs are both off, 

.

Make sure that the IP address and the subnet mask of the Prestige and the 

computers are on the same subnet.

The Prestige cannot 

get an IP address 

from the ISP.

The ISP provides the 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). Verify your Ethernet settings, 

. 

Table 30   Troubleshooting Internet Access

I cannot access 

the Internet.

Make sure the Prestige is turned on and connected to the network.
Verify your Ethernet settings, 

Make sure you entered the correct user name and password.

Internet 

connection 

disconnects.

Contact your ISP. 

Table 31   Troubleshooting the Password

I cannot access the 

Prestige.

The username is admin. The default password is 1234. The Password and 

Username fields are case-sensitive. Make sure that you enter the correct 

password and username using the proper casing.
If you have changed the password and have now forgotten it, you will need to 

restore the default configuration file (

). This restores 

all of the factory defaults including the password.
