3 Initial Configuration and Setup
The Technicolor Wireless Gateway is configured using the Web UI
3.1 Accessing the WebUI
Procedure
There are 3 interfaces for the user/operator to connect to on the CGM4231:
• LAN (Default URL 192.168.0.1 on LAN side)
• Cable Modem (CM IP on the WAN side)
• eRouter (eRouter IP on the WAN side)
Apart from these 3 interfaces, there are 2 user levels, Home User and Advanced User.
When the user connects to the WebUI, the page prompts the user enter the username and
password. There is no user name and password set on default for the home user. On boot-up,
the user can login to the WebUI by pressing <ENTER> and the user will be directed to a page to
set the user name and password. After doing so, the user is directed again to the login page to
login to the system with new credentials.
For the advanced user, the user name is admin and the password would be the generated
password of the day.
Figure 3.1
The various pages on the WebUI may be accessible once the credentials are accepted.
