DSL connection blocked

Every time my computer starts I get a message “new private network detected”, and Comodo shows that services.exe, system and svchost.exe are using internet, but I can’t even open a “google” page. I unplugged the cable modem (I have used DSL connection until now), so I’m writing this message using dial-up. Can anyone help me resolve this the problem? Thank you very much!
p.s sorry for my bad english (:SHY)

When you installed Comodo and after rebooting you should have seen a box about new network found. At that you should have click ok. You can go into and add you network manually.
