    First we need to find out if your computer is receiving an IP Address when plugged into the router. Please try the following.
    Click on Start > Run > Type “CMD” (no quotes) and hit enter,
    This will open a command prompt. Within the prompt type “ipconfig” (no quotes).
    Search for the lines that say IP Address, Subnet Mask, and Gateway.
    The 3 should be somewhat like the example. IP Address: 192.168.1.100, Subnet Mask: 255.255.255.0, Gateway: 192.168.1.1. Your results should have different numbers but should be formatted somewhat the same.

    If the above steps are like I described then lets move on….
    1. Try to ping the gateway that you have listed on your computer. To do this, Stay in the command prompt and type “ping 192.168.1.1” (remember I want you to ping the gateway that is listed on your computer) If this does not reply then stop here. We need to figure out why this is.
    2. Try to ping an external Server IP Address. – Type “Ping 8.8.8.8” This will ping one of googles public servers. If this does not reply then stop here, We need to figure out the issue.
    3. Try to ping google by Hostname – Type “ping http://www.google.com” within a command prompt. Let me know if this is successful or not.

    If everything checks out to be ok then we will need to begin checking your browser settings.
