Sometimes when trying to get onto a website, it says the page cannot be loaded, even though the icon in the taskbar shows that the computer is connected to the internet. Repairing the connection sometimes helps, other times I have to repair it several times. But when I try going on to another website, the same thing happens. This usually happens when I first try going on the Internet after starting the computer, and goes on for a while until it seems to settle down. When it can’t connect I can ping the router and the DNS servers, as well as connect to the network. This problem happens with some of the computers on the network, (Windows XP as well as Windows 7) while others work fine. The computers that don’t give the problem are both wired and wireless. I tried using the netsh int command and the winsock reset command, but this didn’t help. What could be causing this problem? If it is the router why is it happening with just some of the computers on the network?
