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 — 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 — 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.
●
Max DHCP Clients — The number of DHCP addresses that can be assigned and active at one
time. It’s recommended you set this to a number greater than the number of Wi-Fi users.
●
DNS Mode — Specifies how the DNS servers (that the DHCP clients are to communicate with)
are obtained. See “DNS Mode” on page 101.
●
Assign a permanent (static) IP address to a device on your network, and view the static
IP assignment list. See “DHCP Static IP Assignment List” below.
DHCP Static IP Assignment List
With DHCP, IP addresses are assigned dynamically; devices typically don’t have a permanent
IP address.
However, in some cases you might want to assign a static (permanent) IP address to a device,
while still using DHCP for the rest of the devices on your network. This is also known as
“DHCP reservation.” You might want to do this with, for example, a Web server, FTP server, media
server.
