[Bug 1607823] Re: Cellular connection drops out

 

@jibel, that behaviour might be considered a bug, I have opened bug
#1608885 for system-settings to address that.

If you see the bug again you can try to execute /usr/share/ofono/scripts
/scan-for-operators and you will see a list like:

<<
Scanning operators on modem /ril_0...
[ /ril_0/operator/21403 ]
    Status = current
    MobileCountryCode = 214
    MobileNetworkCode = 03
    Name = Orange
    Technologies = gsm umts 

[ /ril_0/operator/21401 ]
    Status = available
    MobileCountryCode = 214
    MobileNetworkCode = 01
    Name = vodafone ES
    Technologies = gsm umts 

[ /ril_0/operator/21404 ]
    Status = available
    MobileCountryCode = 214
    MobileNetworkCode = 04
    Name = Yoigo
    Technologies = gsm umts 

[ /ril_0/operator/21407 ]
    Status = available
    MobileCountryCode = 214
    MobileNetworkCode = 07
    Name = movistar
    Technologies = gsm umts

You can force one or another operator by doing:

phablet@ubuntu-phablet:/usr/share/ofono/scripts/test-network-
registration <path>

being path something like /ril_0/operator/XXXXX, as in scan-for-
operators output. Check if forcing your operator to Free changes
something.

Bug description:
  MX4 running 379 from 7/15

  I recently noticed the phone was Searching for a signal for some time, even though I know it was connected just prior.
  Wifi is disabled.

  The attached syslog shows the modem disconnecting and reconnecting
  several times throughout the morning.
