Hi Mew.
Could you go to start and click run then type cmd and hit enter.
a dos prompt will appear, so type ipconfig and hit enter and let me know what the IP Address is.
Then from the dos prompt type ping yahoo.com and hit enter and let me know of it says reply or if it says request timed out.
Thanks
