[SOLVED] Lost internet connection (diagnostic log inside)

[t928]

Hi,

I have 2 machines behind a router. One works fine, the other lost internet this morning.

The router is fine, all the lights under 'dsl', 'internet' and the corresponding jacks for each computer are on.

So the problem is with this one pc.

I have tried maybe 10-12 times using the automatic repair facility in xp. I have tries restarting the computer (roughly 10 times) and the router (3 times).

'm not sure how to proceed. This is the log from the diagnostic, any help greatly appreciated
