Wireless connectting problem on 13.2

I install openSUSE 13.2 by updating from 13.1,and there is a problem on the wireless connection. The problem is: I must reboot to use the wireless connection. When the first time I start my computer and connect to the wireless net, it shows the the net is connected on the taskbar but the net is not working. I can not connect the internet. when I restart the computer, the net works. My computer is T430. How can I solve the problem? Thank you.
