This equipment has been tested and found to comply with the limits for a Class B digital device,
pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection
against harmful interference in a residential installation. This equipment generates, uses and can
radiate radio frequency energy and, if not installed and used in accordance with the instructions,
may cause harmful interference to radio communications. However, there is no guarantee that
interference will not occur in a particular installation. If this equipment does cause harmful
interference to radio or television reception, which can be determined by turning the equipment off
and on, the user is encouraged to try to correct the interference by one or more of the following
measures:
•Reorient or relocate the receiving antenna.
•Increase the separation between the equipment and receiver.
•Connect the equipment into an outlet on a circuit different from that to which the receiver
is connected.
•Consult the dealer or an experienced radio/ TV technician for help.
This device complies with part 15 of the FCC Rules. Operation is subject to the following two
conditions:
1）This device may not cause harmful interference.
2）This device must accept any interference received, including interference that may cause
undesired operation.
Any changes or modifications not expressly approved by the party responsible for compliance

Chapter 3. Quick Installation Guide
This chapter will show you how to configure the basic functions of your TL-WR841ND 300Mbps
Wireless N Router using Quick Setup Wizard within minutes.
3.1 TCP/IP Configuration
The default domain name of the TL-WR841ND 300Mbps Wireless N Router is
http://tplinklogin.net, the default IP address is 192.168.0.1, 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 ports of the Router. And then you can configure the IP address
for your PC in the following way.
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
between your PC and the Router. The following example is in Windows XP.
Open a command prompt, and type ping 192.168.0.1, and then press Enter.
¾If the result displayed is similar to the Figure 3-1, it means the connection between your PC
and the Router has been established well.
Figure 3-1 Success result of Ping command
¾If the result displayed is similar to the Figure 3-2, it means the connection between your PC
and the Router is failed.
