N750 WiFi Router
Change the LAN TCP/IP Settings
The router is preconfigured to use private IP addresses on the LAN side and to act as a
DHCP server. The router’s default LAN IP configuration is as follows:
•
LAN IP address
. 192.168.1.1
•
Subnet mask
. 255.255.255.0
These addresses are part of the designated private address range for use in private networks
and are suitable for most applications. If your network requires a different IP addressing
scheme, you can change these settings.
You might want to change these settings if you need a specific IP subnet that one or more
devices on the network use, or if you use competing subnets with the same IP scheme.
To change the LAN TCP/IP settings:
1.
Launch a web browser from a computer or wireless device that is connected to the
network.
2.
Type
or
.
A login screen displays.
3.
Enter the user name and password.
The user name is
admin
. The default password is
password
. The user name and
password are case-sensitive.
The BASIC Home screen displays.
4.
Select
ADVANCED > Setup > LAN Setup
.
5.
In the
IP Address
field, type the IP address.
6.
In the
IP Subnet Mask
, type the subnet mask of the router.
The IP address and subnet mask identify which addresses are local to a specific device
and which must be reached through a gateway or router.

Change the RIP settings.
Router Information Protocol (RIP) allows a router to exchange routing information with
other routers.
a.
Select a RIP direction:
•
Both
. The router broadcasts its routing table periodically and incorporates
information that it receives.
•
Out Only
. The router broadcasts its routing table periodically.
•
In Only
. The router incorporates the RIP information that it receives.
b.
Select a
RIP
version:
•
Disabled
. This is the default setting.
•
RIP-1
. This format is universally supported. It is adequate for most networks,
unless you are using an unusual network setup.
•
RIP-2
. This format carries more information. Both RIP-2B and RIP-2M send the
routing data in RIP-2 format. RIP-2B uses subnet broadcasting. RIP-2M uses
multicasting.

Click the
Apply
button.
Your changes are saved.
If you changed the LAN IP address of the router, you are disconnected when this change
takes effect.

To reconnect, close your browser, relaunch it, and log in to the router
Specify the IP Addresses That the Router Assigns
By default, the router acts as a Dynamic Host Configuration Protocol (DHCP) server. The
router assigns IP, DNS server, and default gateway addresses to all computers connected to
the LAN. The assigned default gateway address is the LAN address of the router.
These addresses must be part of the same IP address subnet as the router’s LAN IP
address. Using the default addressing scheme, define a range between 192.168.1.2 and
192.168.1.254, although you can save part of the range for devices with fixed addresses.
To specify the pool of IP addresses that the router assigns:
1.
Launch a web browser from a computer or wireless device that is connected to the
network.
2.
Type
or
.
A login screen displays.
3.
Enter the user name and password.
The user name is
admin
. The default password is
password
. The user name and
password are case-sensitive.
The BASIC Home screen displays.

5.
Make sure that the
Use Router as DHCP Server
check box is selected.
6.
Specify the range of IP addresses that the router assigns:
a.
In the
Starting IP Address
field, type the lowest number in the range.
This IP address must be in the same subnet as the router.
b.
In the
Ending IP Address
field, type the number at the end of the range of IP
addresses.
This IP address must be in the same subnet as the router.
7.
Click the
Apply
button.
Your settings are saved.
The router delivers the following parameters to any LAN device that requests DHCP:
•
An IP address from the range that you define
•
Subnet mask
•
Gateway IP address (the router’s LAN IP address)
•
DNS server IP address (the router’s LAN IP address)
Disable the DHCP Server Feature in the Router
By default, the router acts as a DHCP server. The router assigns IP, DNS server, and default
gateway addresses to all computers connected to the LAN. The assigned default gateway
address is the LAN address of the router.
You can use another device on your network as the DHCP server or specify the network
settings of all your computers.

(Optional) If this service is disabled and no other DHCP server is on your network, set your
computer IP addresses manually so that the computers can access the router.
Manage Reserved LAN IP Addresses
When you specify a reserved IP address for a computer on the LAN, that computer always
receives the same IP address each time it accesses the router’s DHCP server. Assign
reserved IP addresses to computers or servers that require permanent IP settings.
