No internet connection after plugging out and in the dock

1 Attachment(s)

Hi,

I have a Targus ACP71EU dock. When plugging my laptop out, and then back in, I lose my Internet connection ; the Ethernet network is working only after a reboot os the OS.
I have this behavior since update to latest firmware 1.3.52.

Any idea on what could be misfunctionning here ?

I also have this problem with version 1.3.52 on Ubuntu 16.04.2 LTS on the latest gen. Dell XPS13. The only way to get Ethernet back is to reboot the machine. I cannot attach a log, sorry.

We've managed to reproduce it on systems like yours, but it looks that any USB ethernet adapter (not necessarily DisplayLink's dock) also behaves the same.
A workaround is to restart NetworkManager with

Code:

sudo service network-manager restart

Did it work with 1.2.x release?

Cheers,
Michal
