Change the LAN IP Address
The modem router is preset with a default LAN IP 192.168.1.1, which you can use to log
in to its web-based management page. The LAN IP address together with the Subnet
Mask also defines the subnet that the connected devices are on. If the IP address
conflicts with another device on your local network or your network requires a specific
IP subnet, you can change it.
Follow the steps below to change your IP address.
Visit
http://tplinkmodem.net
, and log in with the password you set for the modem
router.
Go to
Advanced
>
Network
>
LAN Settings
page and select
IPv4
.
Type in a new
IP Address
appropriate to your needs.
Select the
Subnet Mask
from the drop-down list. The subnet mask together with
the IP address identifies the local IP subnet.
Keep
IGMP Snooping
as enabled by default. IGMP snooping is the process of
listening to IGMP (Internet Group Management Protocol) network traffic. The
function prevents hosts on a local network from receiving traffic for a multicast
group they have not explicitly joined.
You can configure the modem router’s
Second IP
and
Subnet Mask
for LAN interface
through which you can also access the web management page.
Leave the rest of the default settings as they are.
Click
Save
to make the settings effective.

Use the Modem Router as a DHCP Server
You can configure the modem router to act as a DHCP server to assign IP addresses to
its clients. To use the DHCP server function of the modem router, you must configure all
computers on the LAN to obtain an IP Address automatically.

Follow the steps below to configure DHCP server.
Visit
http://tplinkmodem.net
, and log in with the password you set for the modem
router.
Go to
Advanced
>
Network
>
LAN Settings
page and select
IPv4
.
Select
DHCP
to enable the DHCP function and select
DHCP Server
.
Specify the
IP Address Pool
, the start address and end address must be on the same
subnet with LAN IP. The modem router will assign addresses within this specified
range to its clients. It is from 192.168.1.100 to 192.168.1.199 by default.
Enter a value for the
Address Lease Time
. The
Address Lease Time
is the amount of
time in which a DHCP client can lease its current dynamic IP address assigned by the
modem router. After the dynamic IP address expires, the user will be automatically
assigned a new dynamic IP address. The default is 1440 minutes.
Keep the rest of the settings as default and click
Save
to make your settings effective.
Note:
1. The modem router can be configured to work as a
DHCP Relay
. A DHCP relay is a computer that forwards DHCP
data between computers that request IP addresses and the DHCP server that assigns the addresses. Each of the
device’s interfaces can be configured as a DHCP relay. If it is enabled, the DHCP requests from local PCs will be
forwarded to the DHCP server that runs on WAN side.
2. You can also appoint IP addresses within a specified range to devices of the same type by using
Condition Pool
feature. For example, you can assign IP addresses within the range (192.168.1.50 to192.168.1.80) to Camera
devices, thus facilitating the network management. Enable DHCP feature and configure the parameters according
to your actual situation on

Reserve LAN IP Addresses
You can view and add a reserved address for a client. When you specify an IP address
for a device on the LAN, that device will always receive the same IP address each time
when it accesses the DHCP server. If there are some devices in the LAN that require
