Can't Establish connection error

[sefub]

Connects to wireless network router but
won't go the further step to connect to the internet. I get a message in
diagnose connection problems like this: "www.google.com" is not set up to
establish a connection on port "World Wide Web service (HTTP)" with this
computer.

I've read the suggestions about removing nortons but I don't have Nortons, running a Toshiba Satellite with Vista, AVG, Zonealarm. When this happens no browsers will work, Chrome,firefox, or IE. Sometimes it will not work for days.

In ZoneAlarm, go to Firewall, Zones. Your network IP and subnet for your
router should be listed in the first entry. You should have Loopback
Adapter, DNS Server, and DHCP Server also listed as Trusted. If not, add
them along with there appropriate IP. You can get the IP addresses from your
router set up. Once that's set up, reboot and see if it works better.
