[Mathieu Trudel-Lapierre <mathieu.tl@xxxxxxxxx>]

Thank you for taking the time to report this bug and helping to make
Ubuntu better. The issue you are reporting is an upstream one and it
would be nice if somebody having it could send the bug to the developers
of the software by following the instructions at
https://wiki.ubuntu.com/Bugs/Upstream/GNOME. If you have done so, please
tell us the number of the upstream bug (or the link), so we can add a
bugwatch that will inform us about its status.

As a workaround, for now you should be able to set "mtu 1430" in
/etc/ppp/options, which should be taken into account when you connect
(but it will affect all ppp connections, including VPN).

Thanks in advance.

Title:
  No option to change MTU for mobile broadband in NetworkManager

Status in Network Manager GNOME Applet:
  New
Status in “network-manager-applet” package in Ubuntu:
  Confirmed

Bug description:
  Mobile broadband connections seem to work best when the MTU is 1430:
  http://ubuntuforums.org/showthread.php?t=1630684

  Currently there is no native way of setting this in NM and I have to change it by this command every time I connect:
  sudo ifconfig ppp0 mtu 1430

  MTU can be set for wired and wireless, why not mobile?

  I suggest that the MTU value should be set on the 'Mobile Broadband'
  tab of a connection under the 'Advanced' section. It should also be
  1430 by default (or some other common recommended value for mobile
  broadband).

  I'm running Natty but I've never seen an option in other releases
  either.
