Wireshark doesn't show TCP UDP detail

I am trying to diagnose a network problem on my company's MacBook. However, all the captured packets are just showing up as "Ethernet (1)" not "TCP" or "UDP". What would cause this? Can I fix it?

Are your dissectors enabled? Check Analyze -> Enabled Protocols and be sure the TCP and UDP dissectors are checked. If you want to, you can choose the Enable All button on the lower-left corner and then hit OK.

Winner, winner. Chicken dinner! That was it.

Glad it was an easy fix for you. And unless you explicitly disabled those dissectors yourself, which seems doubtful, you may have been a victim of a practical joke.

It's possible I did that but I don't remember it. I may have just enabled TCP UDP for some reason. I didn't bother scrolling the whole list before enabling everything. I am at home by myself and I'm certain she didn't play that practical joke on me. It's possible that the MacPorts version of Wireshark is configured like this.
