Hi!

I started with a completely new ubuntu installation (ubuntu-14.04.1lts-lubuntu-odroid-u-20140814). My device is connected with ethernet and I plugged in a wlan stick. I am accessing the computer via vnc (of course via ethernet).

Using gnome network manager I connect to my wireless network. When I start Wireshark in promiscuous mode odroid's ethernet connection is lost immediately and of course vnc stops working.

This is what syslog tells me:

What is happening here and how can I prevent it? Thanks for your help!

As your platform is a SOC (Odroid), the problems could be related to the ethernet chipset, which seems to be something that's bridging USB to Ethernet !?!

http://www.hardkernel.com/main/products/prdt_info.php?g_code=G138745696275&tab_idx=2

HSIC Ethernet controller    LAN9730HSIC USB 2.0 to 10/100 Ethernet controller with HP Auto-MDIX from SMSC/Microchip

So, if you have problems with your WLAN, especially if that's a USB dongle, it could be related to that chip or the driver.

I guess you will get a better answer in an Odroid forum, as others might have experienced the same problem.
