Pls Open a cmd window and issue the following command and post it.
You may not have a valid default gateway or dns server ip addr from
the output.


click on windows start -> run -> cmd

... you will get a dos/cmd window ...

ipconfig /all

You can also issue the following 2 cmds to reset the network

ipconfig /release

wait 30 secs

ipconfig /renew


Another test is to ping a known ip address like www.yahoo.com from the cmd window and if you have a good connection it should look like below

C:\ ping www.yahoo.com
