Hmmm. OK, follow this http://www.wikihow.com/Ping-an-IP-Address
But first you need to find the IP of your router. So, in the instructions, after step 1, before step 2 ( where you type ping ), type "ipconfig" with no apostrophes.
Write down the number after Default Gateway. It'll be 192.168. something . something.
That's the number you ping.
So for me :
C:\Documents and Settings\Chris>ipconfig
Windows IP Configuration
Ethernet adapter Local Area Connection 2:
Media State . . . . . . . . . . . : Media disconnected
Ethernet adapter Wireless Network Connection:
Connection-specific DNS Suffix . :
IP Address. . . . . . . . . . . . : 192.168.1.100
Subnet Mask . . . . . . . . . . . : 255.255.255.0
Default Gateway . . . . . . . . . : 192.168.1.1
I write down 192.168.1.1
Then I do this :
C:\Documents and Settings\Chris>ping 192.168.1.1
Pinging 192.168.1.1 with 32 bytes of data:
