Recently my internet won't connect. The diagnostic tool comes up with the
following - the problem is probably a firewall, check HTTP port (80) HTTPS
port (443) FTP port (21). I can't find these ports. My ISP says there is
nothing wrong their end so it must be the computer. I have a Norton
(Symantec) firewall which is switched off and a windows firewall which is
switched off. Any ideas please?
Open the Norton Security application then click on Task and settings then
click on change advanced settings.
On the Advanced settings click on Firewall Protection settings, make sure
the Firewall is ON then click on
Firewall Program Rules and make sure the Network is allowed access and the
IE also.
