Welcome to TSG:
Looks like you have a working ethernet connection.
Any error msgs when trying to connect.?
Let's see the result of pings from the following :

From a Johnwill post on the Networking Forum


Try these simple tests.

Hold the Windows key and press R, then type CMD (COMMAND for W98/WME) to open a command prompt:

In the command prompt window that opens, type type the following commands one at a time, followed by the Enter key:

NOTE: For the items below surrounded with < >, see comments below for the actual information content, they are value substitutions from the previous IPCONFIG command output! Do NOT type <computer_IP_address> into the command, that won't work. Also, the < and > in the text is to identify the parameters, they are also NOT used in the actual commands.

Do NOT include the <> either, they're just to identify the values for substitution.

IPCONFIG /ALL

PING <computer_IP_address>

PING <default_gateway_address>

PING <dns_servers>

PING 8.8.8.8

PING yahoo.com

Right click in the command window and choose Select All, then hit Enter to copy the contents to the clipboard.
Paste the results in a message here.

<computer_IP_address> - The IP Address of your computer, obtained from the IPCONFIG command above. (For Vista/Win7, the IPv4 Address)

<default_gateway_address> - The IP address of the Default Gateway, obtained from the IPCONFIG command above.

<dns_servers> - The IP address of the first (or only) address for DNS Servers, obtained from the IPCONFIG command above.

If you are on a machine with no network connection, use a floppy, USB disk, or a CD-RW disk to transfer a text file with the information to allow pasting it here.

you don't appear to have a valid DNS address
------------------------------------------------------------------------

TCP/IP stack repair options for use with Vista/Windows 7.

Start, Programs\Accessories and right click on Command Prompt, select "Run as Administrator" to open a command prompt.

Note: Type only the text in bold for the following commands.

Reset WINSOCK entries to installation defaults: netsh winsock reset catalog

Reset IPv4 TCP/IP stack to installation defaults. netsh int ipv4 reset reset.log

Reset IPv6 TCP/IP stack to installation defaults. netsh int ipv6 reset reset.log

Reboot the machine.

If you receive the message
The requested operation requires elevation.
Then please open the command prompt as administrator - as requested above
Start, Programs\Accessories and right click on Command Prompt, select "Run as Administrator" to open a command prompt.


Post back the results here - we need to know these commands worked correctly
rightclick in the box
select all
enter
control key + C key - to copy
then reply here and
control key + V to paste

5. Right click on Local Area Connection and choose Properties. If Windows say it needs your permission to continue, click Continue.
6. Select Internet Protocol Version 4(TCP/IPv4) and click Properties.
7. Select Obtain an IP address automatically.
8. Select Obtain DNS server address automatically.
9. Click OK to close the TCP/IP Properties window.
10. Click OK to close the Local Area Connection Properties window.

the ping tests show the DNS issue as you can ping IP address on the internet but not by a name
did you try the other suggestions from pedroguy - re setting the DNS

you could try using google open dns
