I have a notebook computer which shows it is connecting to our wireless server, but I can't get online. It was working fine until yesterday when I went to the library with my computer. The library also has a has a wireless server. My computer hooked up to it, but I needed to sign up with a passcode to go online. So I didn't bother. I came home and couldn't get online, even after rebooting twice. I sent you guys a shout for help, then it started working properly on its own. Today, I went to the library again with my notebook computer and didn't even try to go online. But now at home I can't get online even though it shows that I'm completely hooked into our wireless server. What is going on???
