Can anyone tell me why I am getting this error message when trying to capture in monitor mode over Wifi (En1) ? I do not get this error until I enable monitor mode. I am trying to capture all traffic on the network.
"Unable to set data link type on interface 'en1' (EN10MB is not one of the DLTs supported by this device)."

What version of Wireshark are you using? There were, as I remember, some bugs that could cause this.

I am on version Version 1.99.9

What happens if you try version 2.0.0rc2?

Success! Thank you, upgrading to the version 2.0.0rc2 solved the issue

With version 2.0.0 (stable 18nov15, on a MacBook-10.7) I found that if I changed the settings for the interface (to enable monitor mode) then restarted the app then I could get it into monitor mode after it restarted. Awkwardly enough I seem to have to repeat the procedure to get it capture in non-monitor mode.

As I posted elsewhere - 2.0 didn't do monitor mode 1.12 did 2.0 couldn't be uninstalled apparently re-installing 1.12 said it installed, but was not there. 2.01 says it installed but is not there - even though 2.0 was thrown away 1.12 cannot be re-installed We were told at Sharkfest you could have both 1 and 2 Now I can’t even get 1.12 back
