I was having the same problem and found out that on linux systems you need to be root to capture any data.
You just have to run:sudo wireshark

The wireshark wiki has lots of helpful information

Not all operating systems support capturing non-data packets and, even on operating systems that do support it, not all drivers, and thus not all interfaces, support it. Even on those that do, monitor mode might not be supported by the operating system or by the drivers for all interfaces. -Wireshark FAQ (http://www.wireshark.org/faq.html#sec10)

More than likely this is an issue with your card's/driver's ability to capture packets. While running it as root user is the first step, you also need a compatible card. I'm not sure what card you have, but the card in the Mini 12 I have does not support it.
