Did you change the order?

I take it you have more than one connection.
I have no idea if I arrived at a correct place (random google search), but since I cannot find an answer to my problem anywhere I decided to ask it myself.
I guess a number of people in the US have used AT&T hotspot. I have one at my university, and the problem is - I cannot disconnect and forget it. I want to use my home wireless network, but I can't.
I'm using Windows 8, of course I tried "forget this network" but it doesn't do anything, it just keeps reconnecting. I tried cmd -> netsh wlan show profiles; and attwifi doesn't appear there. I called AT&T customer service, but they had no solution. Now I am forced to use a very slow AT&T hotspot instead of my home connection from TimeWarnerCable.
I don't have this problem on my mobile phone and on another laptop. The laptop which encounters this problem is a a Lenovo Z50.
Any ideas would be greatly appreciated.
