Changed to ATT Uverse and now my laptop keeps saying acquiring IP address with excellent strength?

I recently changed from ATT DSL to ATT Uverse and every time I turn on my computer it states acquiring IP address. It has all green bars and states excellent strength. Sometimes it eventually connects and sometimes it never does. I didn't have this problem until I switched. Other laptops, my phone and TV are able to connect. Is there something I need to change on my computer or is this an ATT U-verse problem|||Remove the network settings from your computer and try to connect again, you have to enter the password again.
