Can see wireless signal but can't browse.

I was about to connect to my school network just fine when but now, i can't browse or anything. I can see the signal but not able to do anything with internet. What have I done to cuased this? How may I solve this issue? Thanks

 

I'm afriad we wont be able to answert this becasue we don't know the setup your school uses, your best bet is to call up and talk to the school administrator.

 

I'd second that. Most schools filter only on known MAC addresses, so if you haven't registered your laptop with your school, you probably can't get online. Talk to the network admin or computing center at your school. And bring your laptop with.

 

It was working fine last couple of weeks until yesterday.

 

Can you connect to any other wireless networks, at a place like Panera or whatnot? If so, then the problem is not with your computer, and they changed a configuration with the network.
What probably happened is someone accidentally pruned you from the allowed users list, and you just need to go fix that. You aren't giving us any more information, so all I've got are guesses. Go ask your school's computing center staff. That's what they're there for.

 

I can connect to my home wireless and you're right, I should go ask the computing staff tomorrow. Thanks
