Specify Your Network Settings

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.
1   Visit

 http://tplinkmodem.net

, and log in with the password you set for the modem 

router. 

2   Go to 

Advanced

 LAN Settings

 page and select

 IPv4

.

 

3   Type in a new 

IP Address

 appropriate to your needs.

4   Select the 

Subnet Mask

 from the drop-down list. The subnet mask together with 

the IP address identifies the local IP subnet.

5   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. 

6   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.

7   Leave the rest of the default settings as they are.
8   Click 

Save

 to make the settings effective.

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.
