Just as the title says, my laptop won't connect. It will connect to my college's wireless network but will not allow me to go to the school's log in page. I just recently purchased this laptop about 16 days ago and it used to work fine until a friend of mine decided to change my homepage for me. Since my college requires me to log in, it DENIES me access to anything online but will show me that I am connected to the INTERNET. I have tried to get HP tech support (was a useless waste of an hour and a half) and have tried to get my computer tutors to help me out, but NONE could fix the problem. I have restored the computer to the first day of a restore point (didn't fix problem) and the windows diagnose didn't even work. A friend of mine has even typed in the login address that shows up on her computer but it still will not work. What can I do to try to get this thing to work?

I'm running on a Microsoft Vista platform, hp computer and am pretty NEW to this stuff. Any help would be appreciated in advance

If I'm not mistaken, Vista uses Defender, correct?

Check your settings there to make sure this program is not preventing you from connecting to the network at school.

Please verify that you are, in fact, using Windows Defender...or please specify your other security software installed on this computer.I don't think it's the anti virus software that's the cause this time, I can use my laptop at home, but not at school. I'm currently using AVG and I'm using the windows firewall.I didn't mean your antivirus software...I meant your firewall software.

Is Windows Defender installed on this computer?

You did say you have Vista, right?  If you can connect at home, but not at school...the problem is that you need to let your firewall know you are connecting to a different network and to allow the connection.  If you do not do this, then you will not be ABLE to connect to the school's network.

There may be other issues, but take a look at your firewall settings, first...I checked like you said and it's still not working.
It used to work at school, why would it change the firewall overnight?
