Hi, I'm having this problem with my windows 7 OS Lenovo Ideapad Y450 laptop. when i try to connect to the internet at home, it connects and before i could go into the internet browser, it drops again. this continues to happen for many times until i couldnt do anything with it. what's the irony is that i have other laptops (vista OS) at home running with no problems , and when i am in school, my Lenovo laptop connects perfectly. no signs of dropping of connection at all.
