internetconnection established, servers not found

[Achilles124]

I have received a new modem from my provider and installed it. No problem with that .... except that there is a problem with my internetconnection. The internetconnection is established. But my computer gives an error every time I want to visit a website:

Server not found.

What could be the problem? And what to do to solve it?

Thanks.

I didn't know whether it was -cl or c1 (I guess -cl). Well, this is the code. I hope you can make sense out of it.

You need to set up the modem, so it gets DNS servers from your ISP.

The problem is solved. Don't know what happened but I think my provider changed some things. Anyway, thank you for answering, both of you. :p
