In order to use the web configurator you need to allow:

• Web browser pop-up windows from your device.
• JavaScripts (enabled by default).

Table 118   Troubleshooting Accessing the Prestige

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 upload 

the default configuration file. This restores all of the factory defaults including the 

password.

I cannot 

access the 

web 

configurator.

Make sure that there is not an SMT console session running.
Use the Prestige’s WAN IP address when configuring from the WAN. Refer to the 

instructions on checking your WAN connection.
Use the Prestige’s LAN IP address when configuring from the LAN. Refer to for 

instructions on checking your LAN connection.
Check that you have enabled web service access. If you have configured a secured 

client IP address, your computer’s IP address must match it. Refer to the chapter on 

remote management for details. 
Your computer’s and the Prestige’s IP addresses must be on the same subnet for LAN 

access.
If you changed the Prestige’s LAN IP address, then enter the new one as the URL.
Remove any filters in SMT menu 3.1 (LAN) or menu 11.5 (WAN) that block web 

service. 
See the following section to check that pop-up windows, JavaScripts and Java 

permissions are allowed.

You may also need to clear your Internet browser’s cache.
In Internet Explorer, click Tools and then Internet Options to open the Internet 

Options screen. 
In the General tab, click Delete Files. In the pop-up window, select the Delete all 

offline content check box and click OK. Click OK in the Internet Options screen to 

close it.
If you disconnect your computer from one device and connect it to another device that 

has the same IP address, your computer’s ARP (Address Resolution Protocol) table 

may contain an entry that maps the management IP address to the previous device’s 

MAC address). 
In Windows, use arp -d at the command prompt to delete all entries in your computer’s 

ARP table.

I cannot 

remotely 

manage the 

Prestige from 

the LAN or 

WAN.

Refer to 

 for scenarios when remote management may not 

be possible. 

Use the Prestige’s WAN IP address when configuring from the WAN. 
Use the Prestige’s LAN IP address when configuring from the LAN.
