Some sites give me a "problem loading page" in Firefox and an error in IE stating: "website (xxx) is online but isn't responding to connection attempts". Then when I reload the page a few minutes later it does work. Then after a while, I get the error again, etc. It happens on both my computer and the laptop of my friend. I have reset the router multiple times, to no effect. I don't use proxy or VPN or anything like that. My computer is connected to the router via cable, and the laptop is wireless. Anyone know what the problem might be?
