AVG FIREWALL doesn't allow my internet connection

I bought and installed the AVG ultimate product (computer and laptop), but when the firewell is on the internet doesn't work at all. If I place settings on 'Disable firewall protection' my connection is back and I can surf, but whent the Firewall is on Automatic the internet doen't work (it seems I conected but I can navegate). I tried with the Interactive mode setting but AVG Internet Security does not ask me for autorisation, so it does not solve the connection problem either.
What can I do?
