So I have this problem on my laptop .
I had to reformat the Hd and so I set up the internet wireless as before but now it won't let me connect.even with the lan cable it's the same. I get the signal ok and it tells me the laptop is connected but if i open IE it just gives me that can't find page..and no programs will connect. now today windows gave me a funny error " ip conflict " or some thing..
I am running windows xp sp 3 fresh install of a Toshiba satellite ..any one please ..
Try typing http://18.104.22.168 into the URL bar. The number is www.google.com's IP address. What I'm thinking is that there may be something wrong with DNS (the protocol used to translate names like "google.com" into IP addresses that computers can understand) on your computer.
