My issue here is unique. There are times when I need to turn the router off while the computer is on. When I turn the router back on, with the computer still on, I want the machine to sense a connection and connect. This does not happen. I'd have to go to the computer, click about and get it connected.
It's not about my Ubuntu 12.10 x64, but also My Mint Cinnamon x64. When I press shutdown, it becaming shutdown. Power indicator of CPU turn off for a second, then the computer turn on. I have to boot from Windows 7 (loader) to turn off my computer.
It might be the same with this case, but I have multi OS installed on my computer with Windows 7 loader.
