4 PC Network Configuration and Login
4.1 PC Network Configuration
Each network interface on the PC should either be configured with a statically defined
IP address and DNS address, or be instructed to automatically obtain an IP address
using the network DHCP server. SR804N provides a DHCP server on its LAN and it
is recommended to configure your LAN to automatically obtain its IP address and
DNS server IP address.
The configuration principle is identical but should be carried out differently on each
operating system.
The following displays the TCP/IP Properties dialog box on Windows XP.

SR804N Cable Modem User Manual

Figure 1 IP and DNS configuration
TCP/IP configuration steps for Windows XP are as follows:
Step1 Choose Start > Control Panel > Network Connections.
Step2 Right-click the Ethernet connection icon and choose Properties.
Step3 On the General tab, select the Internet Protocol (TCP/IP) component
and click Properties.
Step4 The Internet Protocol (TCP/IP) Properties window appears.
Step5 Select the Obtain an IP address automatically radio button.

This page also displays IP lease information, including the current IP address of the
cable modem, the duration of both leases, the expiration time of both leases, and the
current system time from the DOCSIS timeserver.
The information on this page can be refreshed at any time by clicking your web
browser‟s Refresh button.
5.1.3 Security
Choose Status > Connection and the following page appears.
Figure 6 Security configuration
To restore factory defaults, select the Yes radio button and click Apply. This will
cause the device to reset. The factory default password is “Broadcom” and is
case sensitive.
Note that you can also change the security password from this page by entering a
new password in both the New Password and Re-Enter New Password fields, and
the current password in the Current User ID Password field. Clicking Apply will
change the password. You do NOT have to restore factory defaults to change the
password.
5.1.4 Diagnostics
Choose Status > Diagnostics and the following page appears.

Figure 7 Diagnostic information
Two utilities are provided for troubleshooting network connectivity: Ping and
Traceroute.
Ping allows you to check connectivity between the CMRG and devices on the LAN.
Traceroute allows you to map the network path from the CMRG to a public host.
Selecting Traceroute from the drop-down Utility list will present alternate controls for
the traceroute utility: To run either utility, make any changes to the default parameters
and select Start Test to begin. The window will automatically be refreshed as the
results are displayed in the Results table.

Figure 10 Setup configuration
Enter the information from the Required Information section as indicated:
1.If your ISP uses DHCP, select “DHCP” for the WAN Connection Type, and enter
Host Name and Domain name if required. OR
If your ISP uses static IP addressing, select “Static IP” for the WAN Connection
Type, and enter the information provided by your ISP for Static IPAddress, Static IP
Mask, Default Gateway, Primary DNS, and Secondary DNS.
2.Enter a unicast MAC address in the Spoofed MAC Address field. Your ISP may
require this to be your PC‟s MAC address. If not, you can simply supply the WAN
side MAC address of the router as your CPE and leave the spoofed MAC address
entry set to all 0‟s, since there will be no spoofing required.
3.Select theApply button. This will reset the CMRG.
At this point, the CMRG is configured for basic use. To connect to the Internet,
you must do the following:
1.Power up the CMRG and wait for it to register with the CMTS and obtain an
Internet-routable IP address
2.Get an IP lease from the internal DHCP server for each PC attached to the
CMRG.

SR804N Cable Modem User Manual

Note that communication on the LAN will work regardless of whether the WAN
connection provided by the cable modem is up. However, you will not be able to
access the Internet until the WAN connection is enabled and has an IP address.
Some configurations settings are retrieved only once from non-volatile storage
when the CMRG first powers up. One such setting is changing the Static WAN IP
address parameters. Any changes to these settings will force the CMRG to reset
so that the new configuration can be read from non-volatile storage.
When this mandatory reset is required, the web interface will notify as follows:
Figure 11 Reload page
Simply wait for the modem to reboot and click on the “RELOAD” link to re-enter the
web interface where you made your last change.
Most configuration items may be changed on the fly without a reboot.
5.2.2 DHCP
Choose Basic > DHCP,and the following page appears.
