I've got an intermittent internet connection which has driven me nuts for weeks. The "page cannot be displayed" message appears after merrily surfing for a while. I can lose the connection for minutes or hours, after being connected for a similar length of time. It's totally indiscriminate. I've tried disabling and even uninstalling the numerous anti- virus and anti-spyware stuff I've got on. And I've turned off the Windows firewall. I've tried different ethernet cables and a different modem. What's wierd is that I can do a successful ping test. I'm out of ideas completely. I run XP with a D-Link modem.
