1.) Check to make sure any WiFi buttons on your laptop are turned on. This button has a symbol that looks like this ((i)) and it usually has a blue glow.
2.) You must have current anti-virus software. The Wi-Fi blocks user without it.
3.) Check your Internet Explorer settings. [No. It can't be another browser. It won't work.]
On the browser toolbar click: Tools - Internet Options - Advanced. Scroll to Security settings and uncheck the settings that ask for certificates and the box in front of Use SSL 3.0.
Then restart your laptop and try clicking on Internet Explorer again.
