3.1 TCP/IP Configuration
The default IP address of the TD-8817 ADSL2+ Ethernet/USB Modem Router is 192.168.1.1. And
the default Subnet Mask is 255.255.255.0. These values can be changed as you desire. In this
guide, we use all the default values for description.
Connect the local PC to the LAN port of the modem router. And then you can configure the IP
address for your PC in the following way.
Obtain an IP address automatically
1) Set up the TCP/IP Protocol in "Obtain an IP address automatically" mode on your PC.
If you need instructions as to how to do this, please refer to Appendix B: "Configuring the
PC”.
2) Then the built-in DHCP server will assign IP address for the PC.
Now, you can run the Ping command in the command prompt to verify the network connection.
Please click the Start menu on your desktop, select run tab, type cmd or command in the field
and press Enter. Type ping 192.168.1.1 on the next screen, and then press Enter.
