Auto, DNS
Relay is enabled by default.
● DHCP Static IP Assignment List — You can assign a permanent IP address to a MAC address,
and view the static IP
assignment list. (See “DHCP Static IP Assignment List” on page 104.)
DHCP
DHCP (Dynamic Host Control Protocol) automatically assigns an IP address to each device on the
network and manages other network configuration information for devices connected to your
network. You do not need to manually configure the IP
address on each device that’s on your
network.
The assigned IP addresses are not permanent (as opposed to when using static IP).
Most ISPs (Internet Service Providers) use DHCP.
Normally, you should enable DHCP, in which case you must configure each device on the
network with one of the following:
● TCP/IP settings set to “Obtain an IP address automatically.”
● TCP/IP bound to the Ethernet connection with DHCP.
If DHCP is disabled, you must configure each device on the network with:
● Fixed (permanent/static) IP address.
● DNS server addresses (provided by Sprint).
Enabling DHCP
1. Log in to the home page.
2. Click Advanced settings > Router > LAN.
3. Next to DHCP Server, select Enable.
Configuring DHCP
To configure DHCP settings, DHCP must be enabled (Advanced settings > Router > LAN >
DHCP
Server).
You can set the following DHCP settings in Advanced settings > Router > LAN:
● DHCP IP Address Range — This is the starting and ending address of the range of IP addresses
available for the device to dynamically (that is, not permanently) assign to computers
connected to it.
The start address must be 192.168.0.10 or above.
The ending address must be 192.168.0.50 or below.
● DHCP Lease Time — This is the amount of time, in minutes, a computer can use its assigned IP
address before it is required to renew the lease. After this time is up, the computer is
automatically assigned a new dynamic IP address.
Enter a number between 2 and 10080.
