Public bug reported:
I usually connect my smartphone to my Mac via USB.
Some years ago I discovered (still on Mac OS X) that in addition to the usual
dial-up connection of my smartphone attached to my Mac there was a WAN
connection on the same device with an IP-adress. I sent a ping on it but no
response. At some point later in time that WAN connection became active as soon
as I attached the smartphone to my Mac and I was connected to the Internet
without any dial-up / PPP but with an ethernet/WAN style connection.
From then on when I wanted to connect to the Internet I just attached the
smartphone via USB.
Now I am on Ubuntu 15.04 (with network-manager 0.9.10.0-4ubuntu15) and when I
attach my smartphone I see the following behaviour of the network-manger:
1) the ususal Ethernet connection as soon as the smartphone is attached and
then my smartphone connects to the Internet
2) something neglects that Ethernet connection and brings it down - I can't
find it anymore
3) with my smartphone still connected to the internet I can tell the network
manager to use my mobile broadband via dial-up
4) it dials up and my smartphone somehow converge this with the existing
connection to the Internet
5) now I can use the Internet from within Ubuntu on my Mac
My provider currently is O2 Deutschland / Telefonica Germany and I have
a prepaid flatrate.
The described behavior works reasonably well but I do see that something
neglects the plug&surf wan/ethernet connection. This may be different
for each and every combination of provider, data plan and smartphone but
perhaps it would be possible to investigate this issue to allow for that
easy plug&surf behavior again.
Thank you!
