I haven't downloaded anything recently and I'm using all the same programs. But I get a 'the page cannot be displayed' message when I try accessing internet explorer. I am really worried, and would be so glad if you could help me out. Thanks,

First try unplugging and plugging in your router and modem. Also try restarting your PC.

What operating system do you have? Does it work if you wire it directly to your router? What kind of router do you have and how is it configured?

Make sure proxy is set to automatically detect settings.

Open INTERNET EXPLORER > TOOLS > INTERNET OPTIONS > CONNECTIONS > LAN SETTINGS
