Ok, My wifi connection works in general. Anything can connect to it. And my Dell Inspiron 1501 laptop was connected to it just fine. And i needed new antivirus software, so i downloaded a Microsoft Live Onecare Demo from the microsoft website. After i downloaded it, i rebooted my comp and my laptop wouldnt connect. the connection stopped working out of nowhere. Everything else can connect to the wifi except my computer. I uninstalled Onecare and its STILL not working. I tried EVERYTHING. If anyone has any good info, PLEASE PLEASE PLEASE help. Thanks!
