Thanks vee_ess,

I have checked many times the settings on TCP/IP. They are ok, so much so that right now I am able to browse with DSL. I reset the modem too a few days ago, but didn't help.

My impression is that if I'm surfing now is because I bypassed the security settings set by the router. To get this browse now, I spent a lot of time, just clicking the 'go' button, without changing the configuration settings.

I wish I knew how to control the firewall settings myself, but there's nothing in the configuration that allows to put my hands on.

What I need is the guy (or girl) who projected this modem!

Hope to get some other feedback
