Right. I got that more often last weekend when I wa
So to summarize, I see the following problems being reported here:
1. vivid/krillin: when mobile data is active, and radio technology
preference is changed, mobile data connection is not always restored.
2. vivid/mako: disable wifi, mobile data connection takes >= 6m to be
restored. Note, when
Also, running mako/vivid-devel/#122, I was able to re-create Jonas'
original bug.
I see a delay of 5-6m between changing radio technology and mobile data
being re-established. I see it going from 2g -> 3g and visa versa.
Looking at the log, when the technology changes, the NM SCPlugin-Ofono
run
The other big problem here is that when I'm connected to wifi, I expect
to have a 3G connection as well so things like MMS will work. Currently
when I'm connected to wifi MMS does not work at all - I cannot recv MMS
attachements because those require a data connection and there doesn't
seem to be o
I see a similar effect on mako vivid-proposed. Sometimes after doing
nothing for a few hours I pick up the phone and find it having no data
connection at all, without any action from me. This could potentially be
because of short 3G network outages. I can confirm that switching from
3G to 2G in the
"sudo service network-manager restart" helps, this recovers the 3G
connection within a few secs.

I've seen some reports of these; but without logs this is the kind of
thing that is impossible to debug.
Could someone seeing this enable debug logs in NetworkManager (editing
/etc/init/network-manager.conf and adding --log-level=debug --log-
domains=core,mb to the Exec line) as well as enabling
I've also reproduced this when disabling wifi, it took nearly 6 minutes
before network-manager tried to activate the ofono context.
