It says i am CONNECTING to the router just fine but when i ping any website or go through a browser i get no response.

I have another pc and that CONNECTS completly fine.

Any suggestions?

I think it might have something to do with the windows management instrumentation as when i go on the PROPERTIES of the connection and go to advanced it says it is corrupt and i need to system restore.... but i dont have any restore POINTS or the original xp cd

PLEASE HELP.

thank you.
 If you are connected wirelessly. The connection may be weak. This is usually because of it being a secure connection. Usually there will be an unsecure connection that will be available. This is what I use, if there is a no other option. Fire wall and other security options can prevent any malicious acts. Is this your own network or someone else's?  What version of XP do you have?

You say that another pc connects fine.  Go to that PC and click Start -> RUN -> cmd -> ipconfig /all
Do the same on the problem pc and then post the results of both.
