Comment 4 for bug 1687262

Live Ubuntu 17.04 session is running OK (mentioned in original report) and it is using:
---------------------------------
$ apt-cache-policy linux-image-generic
linux-image-generic:
  Installed: 4.10.0.19.21
  Candidate: 4.10.0.19.21
  Version table:
 *** 4.10.0.19.21 500
        500 http://archive.ubuntu.com/ubuntu zesty/main amd64 Packages
        100 /var/lib/dpkg/status
$ uname -a
Linux ubuntu 4.10.0-19-generic #21-Ubuntu SMP Thu Apr 6 17:04:57 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux
---------------------------------

So, I did not go in suggested direction of checking upstream kernels...

Instead, I tried manual network configuration though, and it worked (see below). So it is definitely not a kernel problem but network configuration/network connection management problem. Not sure, where this bug has to be reassigned.
