Possible cause 1 of 2:

You may need to change some settings if you've installed third party security software on your computer. If your firewall or anti-virus program isn't correctly set up, you can't browse the internet even though you've established a connection.


What you need to do
Open your firewall or anti-virus program and check that your browser is allowed to establish a connection to the internet.
