[Bug 1418077] Re: NM fails to create a cellular data connection for a unacceptably long time

 

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 this happens, be sure to check 'nmcli d', as
there's been an outstanding indicator-network bug around *forever* about
too much latency between panel icon changes.   See bug #1339792.

3. Hearsay ( from pmcgowan ) that these problems occur on RTM too?

4. Reports from pitti that mobile data occasionally drops and isn't
restored.  @pitti, what device are you using?  This sounds similar to a
bug #1425987 reported by Jean Baptiste.

5. No mobile data connection when WiFi connection active; this affects
MMS.

So...  let's keep this bug for discussions related to the original
problem, ie. when the radio data technology is changed, NM takes ~5-6m
to restore mobile data connection.

If problem with disabling WiFi can be reproduced, then Ken, please file
a new bug for it.

Let's use Jean-Baptiste's bug to track cellular connection dropping and
not being restored.

Bill, please file a new bug regarding your MMS issue.  We actually do in
fact keep the mobile data connection active when WiFi is activated, NM
just changes the default route.  Note, you may be seeing issues due to
issues with US operators.
