● DHCP Static IP Assignment List — You can assign a permanent IP address to a MAC address,<br />

and view the static IP assignment list. (See “DHCP Static IP Assignment List” on page 104.)<br />

DHCP<br />

DHCP (Dynamic Host Control <strong>Pro</strong>tocol) automatically assigns an IP address to each device on the<br />

network and manages other network configuration information for devices connected to your<br />

network. You do not need to manually configure the IP address on each device that’s on your<br />

network.<br />

The assigned IP addresses are not permanent (as opposed to when using static IP).<br />

Most ISPs (Internet Service <strong>Pro</strong>viders) use DHCP.<br />

Normally, you should enable DHCP, in which case you must configure each device on the<br />

network with one of the following:<br />

● TCP/IP settings set to “Obtain an IP address automatically.”<br />

● TCP/IP bound to the Ethernet connection with DHCP.<br />

If DHCP is disabled, you must configure each device on the network with:<br />

● Fixed (permanent/static) IP address.<br />

● DNS server addresses (provided by <strong>Sprint</strong>).<br />

Enabling DHCP<br />

1. Log in to the home page.<br />

2. Click Advanced settings > Router > LAN.<br />

3. Next to DHCP Server, select Enable.<br />

Configuring DHCP<br />

To configure DHCP settings, DHCP must be enabled (Advanced settings > Router > LAN ><br />

DHCP Server).<br />

You can set the following DHCP settings in Advanced settings > Router > LAN:<br />

● DHCP IP Address Range — This is the starting and ending address of the range of IP addresses<br />

available for the device to dynamically (that is, not permanently) assign to computers<br />

connected to it.<br />

The start address must be 192.168.0.10 or above.<br />

The ending address must be 192.168.0.50 or below.<br />

● DHCP Lease Time — This is the amount of time, in minutes, a computer can use its assigned IP<br />

address before it is required to renew the lease. After this time is up, the computer is<br />

automatically assigned a new dynamic IP address.<br />

Enter a number between 2 and 10080.<br />
