Howto - automatically recover your modem and mobile data after deep sleep

[arno_nuehm]

As many of you know, there are problems with Mobile Data connection and modem waking up in a different state after deep sleep.
So I have come up with a solution that is automatic and does not require rebooting the phone.

Yes, I know it's nasty but the modem behaviour is so painfully unpredictable.

Have you tried the following?

Restart modem with

Code:

mmcli -m any --command='AT+CFUN=1,1'

and activate mobile data with

Code:

nmcli c up Internet

with "Internet" replaced by the name of your mobile data connection name.

It works quite fine in a script and a sleep of 30 seconds between the two commands.
