I have a laptop connected to a Sky WIFI router and I can reach the internet, however when I try and go to Google I get a message saying that the site is unreachable, however the network is ok. Could this be a fire wall issue?
This link won't open for me as it's blocked by my PC security with message;
"Visiting an untrustworthy website has been prevented
One or more of this website's certificates are invalid, so we can't guarantee its authenticity. This happens when the website's owner hasn't updated the certificate in time, or if it's a fake site created by scammers. Visiting a website like this makes you more vulnerable to attack."
