I've recently become interested in networking, especially the administrative side of it (monitoring them, managing and resolving faults etc.) and therefore I thought one of the best ways I could learn was to see what was actually happening on them.
I installed Wireshark for Ubuntu, and everything seems to work fine when monitoring my own traffic. The problem I am facing is, when setting the Wireless Adaptor to 'Monitor' mode so that I can view what is happening on the rest of my network, it shall run for a couple of seconds before crashing with the error:
Unknown message from dumpcap, try to show it as a string: Can't restore interface wlan0 wireless mode (SIOCSIWMODE failed: Operation not permitted).
Please adjust manually.
The network adapter on which the capture was being done is no longer running; the capture has stopped.
I don't really know what the problem is, the Wireshark output is just filled with tens of thousands of messages from a wireless printer before the adapter fails. If I end it manually before the adapter crashes, it shall still show up with the same errors.
My guess is it can't put it back into Managed mode, however I don't know why it crashes when running.
Any help would be greatly appreciated!
