SBR-AC1750: LAN Subnet Setup

How do I configure the LAN settings in the SBR-AC1750?

Just as the WAN interface of the SBR-AC1750 can be configured for a customized setup, the SBR-AC1750 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 SBR-AC1750 is 192.168.0.1.  This document describes how to change the LAN IP address and DHCP range of the SBR-AC1750.
 
NOTE: If the LAN IP address is modified to be in a different subnet (e.g. 192.168.8.1), the SBR-AC1750 will automatically change the DHCP range to use addresses in that subnet.

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.

   a.   IP Address - Enter the desired IP address for the LAN interface here.  In this example, 192.168.1.1 is used. 
    
   NOTE: The LAN IP address used must be a private IP address (within one of the following ranges):
    
   10.0.0.x - 10.255.x.x
   172.16.x.x - 172.31.x.x
   192.168.x.x - 192.168.x.x

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.

3. Move the mouse-cursor over the LAN tab and select the LAN - Settings drop-down submenu.  The LAN-Settings page appears.
4. Enable DHCP Server:
   • If it is desired to have the SBR-AC1750 give IP addresses to all of the devices automatically, leave this setting at Enabled.
   • If some devices are manually configured with IP addresses, but others are to receive an address from the SBR-AC1750, leave this setting at unchecked.
   • If there is another device on the network that will be the DHCP server, change this setting to unchecked.
   • If it is desired to manually configure each device with an IP address, change this setting to unchecked.
   NOTE: If the Enabled DHCP Server option has been set to unchecked, skip down to step 8.
    
5. Starting IP Address - This setting classifies the first IP address to be used in the DHCP range.
6. End IP Address - This setting classifies the last IP address to be used in the DHCP range.
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 SBR-AC1750.
8. Click the Apply button.
