11. 1. 1. Change the LAN IP Address
The router is preset with a default LAN IP 192.168.1.1, which you can use to log in to
its web 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 in 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 router.
2. Go to Advanced > Network > 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 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 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.
11. 1. 2. Use the Router as a DHCP Server
You can configure the router to act as a DHCP server to assign IP addresses to its clients.
To use the DHCP server function of the router, you must configure all computers on the
LAN to obtain an IP Address automatically.
