Question
How do I configure the LAN settings in the SBG6782?
Answer

Just as the WAN interface of the SBG6782 can be configured for a customized setup, the SBG6782 also includes configurable options for the Local Area Network (LAN).  The LAN IP Address and DHCP range can be configured and modified to suit the needs of the network.  By default, the LAN IP address of the SBG6782 is 192.168.0.1.  This document describes how to change the LAN IP address and DHCP range of the SBG6782.

NOTE 1: If the LAN IP address is modified to be in a different subnet (e.g. 192.168.5.1), the SBG6782 will automatically change the DHCP range to use addresses in that subnet.

NOTE 2: The subnet mask of the SBG6782 (255.255.255.0) cannot be modified.


Changing the Local Area Network (LAN) IP Address

  1. Launch a web browser, such as Internet Explorer, Firefox, or Safari.  Enter http://192.168.0.1 into the address box, and press the Enter key.  The Login page appears.

    NOTE: By default the LAN IP address is 192.168.0.1.  If the default address has been changed, enter the custom address in the address box.
     
  2. On the Login page:
    a.   Enter admin in the Username field.
    b.   Enter motorola in the Password field.
     
    NOTE 1:  For units that have been leased or purchased by Shaw Communications, the username is cusadmin, and the password is the Customer S/N (Serial Number), located on a white sticker on the bottom of the unit.

    NOTE 2:  If the unit has been leased or purchased by Time Warner Cable, and the admin username and motorola password does not allow access to the GUI, please contact Time Warner for assistance.

    c.   Click the Login button.  The Home page appears.

  3. Move the mouse-cursor over the Basic tab and select the DHCP sub-link.  The Basic - Setup page appears.
  4. On the Basic Setup page:
    a.   LAN IP Address
    - Enter the desired IP address for the LAN interface here.  In this example, 192.168.8.1 is used. 

    NOTE: The LAN IP address used must be a private IP address (within one of the following ranges):

    10.x.x.x
    172.16.x.x - 172.31.x.x
    192.168.x.x

    b.   Scroll down to the bottom of the page, and click the Apply button.

Configuring the DHCP settings

  1. Launch a web browser, such as Internet Explorer, Firefox, or Safari.  Enter http://192.168.0.1 into the address box, and press the Enter key.  The Login page appears.

    NOTE: By default the LAN IP address is 192.168.0.1.  If the default address has been changed, enter the custom address in the address box.
     
  2. On the Login page:
    a.   Enter admin in the Username field.
    b.   Enter motorola in the Password field.
     
    NOTE 1:  For units that have been leased or purchased by Shaw Communications, the username is cusadmin, and the password is the Customer S/N (Serial Number), located on a white sticker on the bottom of the unit.

    NOTE 2:  If the unit has been leased or purchased by Time Warner Cable, and the admin username and motorola password does not allow access to the GUI, please contact Time Warner for assistance.

    c.   Click the Login button.  The Home page appears.

  4. Enable DHCP Server:
    • If it is desired to have the SBG6782 give IP addresses to all of the devices automatically, leave this setting at yes.
    • If some devices are manually configured with IP addresses, but others are to receive an address from the SBG6782, leave this setting at yes.
    • If there is another device on the network that will be the DHCP server, change this setting to no.
    • If it is desired to manually configure each device with an IP address, change this setting to no.

    NOTE: If the DHCP Server option has been set to no, skip down to step 8.
     
  5. Starting Local Address - This setting classifies the first IP address to be used in the DHCP range.
  6. Max Number of Network Devices - This will classify how many IP addresses are to be used in the DHCP range.  For example, if this option is set to 100, and the Starting Local Address is set as 192.168.0.100, then the DHCP range will be from 192.168.0.100 - 192.168.0.199.
  7. Lease time - This is the amount of seconds that a device will keep an IP address, if that device has received an IP address automatically from the SBG6782.
  8. Click the Apply button.
