Ethernet works, wireless doesn't

I had wireless internet with AT&T and everything was fine. Today I switched to Bright House and my laptop will not connect wirelessly to the router. I am able to use the ethernet cord to connect and my mobile devices connect to the wireless network with no problem. Please help ! My computer is an Acer and is operating on Windows 7

Hey Ashp10. You had AT&T as your ISP, but now you are using Bright House, correct?. Did you have your own router when with AT&T or were you using a combo modem/router provided by them. How about with Bright House, are you using a box provided by them or are you using your own router?.
