ping 192.168.2.1
If a message similar to the following appears:
Pinging 192.168.2.1 with 32 bytes of data:
Reply from 192.168.2.1: bytes=32 time=2ms TTL=64
…a communication link between your computer and the Router has been successfully
established.
If you get the following message:
Pinging 192.168.2.1 with 32 bytes of data:
Request timed out.
…there may be something wrong in your installation procedure.
Check the following items in sequence:
1. Is the Ethernet cable correctly connected between the Router and the computer? The LAN
LED on the Router and the Link LED of the network card on your computer must be on.
2. Is TCP/IP properly configured on your computer? If the IP address of the Router is
192.168.2.1, the IP address of your PC must be from 192.168.2.2 - 254 and the default
gateway must be 192.168.2.1. If you can successfully ping the Router you are now ready to
connect to the Internet!
