I upgraded my Ubuntu-studio 13.10 yesterday (via do-release-upgrade) from 12.04. Now my wireless doesn't work properly: I can see the wireless networks and the PC can connect, but internet just won't work. Internet works fine with wired connection. I know there's other questions with similar problems, but none of the solutions have worked for me. Here's some system info that may be relevant:
