No Internet through a router

This would prove helpful and some greater detail would not go astray either.

But as many others here would say you would get a faster responce if you where to post this in the Q & A section as it strictly isn't a discussion topic.

How does windows connect through the modem without the router? (ID username, password etc.)?
Normally you should configure your router to pass on this information to your Internet Provider through the modem...

And just run the internet connection wizard again to get the connection.

Once this is done it will work but you can not setup the internet directly through the modem and then expect it to work through a router.

Sorry, have to ask the stupid questions first .. Are you configuring the Router to connect to the Internet? From what I'm reading here your friend is treating his router like a hub (which isn't the case). Most routers have a Web Based configuration which you use to connect to the net.

Reset the cable modem and then the router in that order. That should work, when the router comes on line it will receive a sync from the modem and the timing will be correct.
