[Bug 1589975] Re: Ubuntu 16.04 has Networking problems

[Stephen Rynas]

Since my original post, I have been poking at the issue. I noticed that
in Ubuntu 16.04 that IPv6 was enabled, on my computer. On my Ubuntu
14.04, IPv6 was set to "ignored".  So I also set IPv6 to "ignored" on
the Ubuntu 16.04. As of yet, I have [B][U]not[/U][/B] noticed any
improvement. Time will tell.

Otherwise, I have noticed that under "My Windows Network", that the
Ubuntu 16.04 computer does not show-up. This seems to imply that there
may be an issue with SMB (Samba).

Title:
  Ubuntu 16.04 has Networking problems

Status in ubuntu-release-upgrader package in Ubuntu:
  New

Bug description:
  Since upgrading to Ubuntu 16.04 from Ubuntu 15.10, Ubuntu 16.04 does
  not properly "see" the home network (LAN). Additionally, my printer
  which is also attached to the LAN does not work correctly.

  These are erratic issues, meaning that they don't appear all the time.
  Further, no crash reports are generated either.

  To explain further. The computer running 16.04 will frequently NOT
  show up on the "network" screen. When I go over to the computer
  running Ubuntu 14.04 it also does not show the computer running 16.04
  as being on the LAN.

  In terms of printing, the printer queue shows the print job as "held".
  When you try to release the print job it asks if the printer is
  connected and then goes back to "holding" the print job.

  These actions seem to imply that networking is not working correctly
  with Ubuntu 16.04.
