3. TCP/IP Configuration
Follow these steps to configure Windows TCP/IP:
•In the Control Panel/Network window, click the TCP/IP entry to select it and click Properties
button.
•In the TCP/IP Properties window, select obtain an IP address automatically.
Note: Do not assign arbitrary IP address and subnet mask to your PCs, otherwise, you will not be able to access
the Internet.
•Click the WINS configuration tab and select Disable WINS Resolution.
•Click the Gateway tab. Highlight any installed gateways and click the Remove button until there
are none listed.
•Click the DNS Configuration tab and select Disable DNS.
•Click OK to save and close the TCP/IP properties window

The following procedure is for the most typical usage of the Prestige where you have a single-user account
(SUA). The Prestige supports embedded web server that allows you to use Web browser to configure it. Before
configuring the router using Browser please be sure there is no Telnet or Console login.
1. Retrieve Prestige Web
Please enter the LAN IP address of the Prestige router in the URL location to retrieve the web screen from the
Prestige. The default LAN IP of the Prestige is 192.168.1.1. See the example below. Note that you can either
use http://192.168.1.1
2. Login first
The default password is the default SMT password, '1234'.
3. Configure Prestige for Internet access by using WIZARD SETUP
The Web screen shown below takes PPPoE as the example.
