Re: Data Connection lost after poor signal

 

It might not be recommended but I would suggest you to restart ofono in the terminal app in order not to have to reboot. sudo restart ofono should do the trick.

I am happy that I am not the only one with that problem, please say that it
affects also you, so we can raise its heat.

However, what I am experiencing here is something different, since I am not
changing the carrier (O2-E+ or Free-Orange), I al always with Wind (IT).

Please note also that for me it is not enough to go to flight mode and back
again :(

 Hi,

At my work office, I am just between my operator atenna and its associated
operator (For french: I'm with Free mobile and when it has low coverage,
Orange will take the relay), when I change room, I lose data/network (A
coworked have his Android app that tell him what operator antenna take the
relay, he is like me on Free mobile, and we observed that some room will
make the swap). My current solution to avoid reboot, is to open network
indicator, switch ON flight mode, wait few secondes, and switch OFF flight mode. Network then comes back faster than a reboot. But we know it is not a
fix, just a workaround.

Hope it will helps you a bit while this network bug got fixed.

Hello everybody.
bq 4.5, r23.

I had this problem sometimes already with r22, and with r23 it got worse.

 Situation: I am temporarily in an area with not-so-good coverage.

 Inside the house at some point there is H connection, if you move a bit
it goes down to E, then other 50cm back to H, then other 50cm no signal at
all and so on.

 What shows up is a _very annoying_ problem.

 When the screen is off and you move from coverage to no coverage and to
coverage again, sometimes (not always! and I do not understand the ratio
behind the frequency) when you have again cellular network the data
connection is nor restored at all.

 The symbol of the net has maybe full power but the one of the data
remains the one with no network. You can call and send and receive SMS's,
but no navigation.

 Turning off and on the data does not change anything, as well as going
to flight mode and back again.

 The only solution is to reboot.

 Obviously rebooting every 20 minutes because you move around the house
and the data connection disappears is _really_ annoying.

 It happened already with r22, but it was not so frequent.

 Any hint on how to investigate the problem?

  Davide
