Plasma Mobile - no data connection

[KNERD]

Just grabbed: Release 202102230241

I see it has gotten a connection to the cell provider by itself, but I am not getting a data connection.

Then looking at the settings, there is absolutely nothing in there at all do for manual settings.

What's going on with that?

I have to restart ofonoctl from time to time. That will probably fix your problem, too.

Check

Code:

ofonoctl wan

If there are details there and it says static, you should have a blank

Code:

ip route

and

Code:

ip a

wwan ip address and to get an ip address and correct default route for you wwan you need to run

Code:

sudo ofonoctl wan --connect

. You should then see an ip address and route to wwan gateway and wwan interface.

If you turn on wifi that will add another default route, for me it has lower priority than the wwan so that is not right.
Then

Code:

ip route

removed the wwan route and thus wifi became the only route.
That is without doing anything, the mobile data icon is still highlighted in the settings.

Turning wifi off:

Code:

ip route

is blank as only wifi route removed as wifi off.

Code:

ip a

shows wwan0 no longer has an p address.

Turning mobile data off and back on:
Nothing changes, as was the case initially.

Weirdly modem was powered off, had to do

Code:

ofonoctl poweron && ofonoctl online

Then

Code:

ofonoctl wan

gave the expected info.
Then you need

Code:

sudo ofonoctl wan --connect

(you can add --append-dns to use the carrier DNS settings.
This then gives you an ip address and route, as before.

Turning mobile data 'off' on the settings has no effect, mobile data is still active - check ip address and route or ping something.

Ok, maybe ignore the wifi on deletes wwan - I did it again and it didn't and wwan has priority - bad.
If you remove the wwan default route / change priority that will fix it or delete the wwan ip address.

Not exactly pretty as it stands today.
But hopefully you can get mobile data working!

I am seeing the same issue being reported on the Manjaro form. They are indicating it seems to be a bug, and Network Manager is not updating

It's been a problem for a month now.

I would think working cellular would be a priority lol.

I am thinking it has been somewhat corrected. I see the checkmark, but still cannot connect. I will try to ssh in and see about the DNS resolv issue as soon as I can

Nope. Still a problem. On every Plasma build not just Manjaro. It connects on first boot after instillation then never again after the second boot. Rhey really need to get rid of the Auto and do a manual network and APN selection like PHOSH uses.

I do have to use these commands regularly when I want to obtain mobile data access.  Sometimes ofono does not recognize the modem.  Sometimes the modem changes from 0 to 1 to even 2.  A quick and dirty fix would be to write a shell script to watch the processes and a cron job to restart them when they go down.  Yet even ofonod likes to sometimes crash to the point where i have to restart the phone.  In other words, sometimes even restarting the daemon does not work.  It is not all front end, I hasten to bet.

Yet I just end up entering the commands by hand through the console when I want to use it.  (I use the up arrow, of course).

One more thing: my network icon says there is no connection even though it works.

Easier way to delete / add ip route for wwan0 (https://forum.pine64.org/showthread.php?...4#pid90474)

Neat on / off mobile data command for Plasma Mobile (not checked with Mobian):

Get ip route for wwan0:

Code:

sudo ip link set dev wwan0 up

Delete ip route for wwan0:

Code:

sudo ip link set dev wwan0 down

It doesn't delete the wwan0 ip address but since there is no route for wwan0 that doesn't make any difference.


Seems like there is always a mobile data connection ready in normal circumstances, still don't know how to enable / disable that 'properly'.

I've posted a script that you may find useful / adapt to your requirements to turn modem on / off and to enable data / disable data:
