Public bug reported:
Reporting this against network manager for want of better information.
Sorry for the imprecise report - I will be glad to observe and update.
Since upgrading to 16.10 I have had problems with my USB "ethernet"
network connection provided by a tethered Android 2.3 device. Initial
connection works well, but after a while Ubuntu looses connection,
indicated by the nm-applet icon switching to "wifi connecting". Ubuntu
seems unable to obtain an IP address. Neither rebooting the laptop nor
restarting the phone help, but after a while the problem goes away on
its own. In the meantime I am able to tether using the phone's wireless
hotspot functionality.
