Public bug reported:
I've been working on an internet issue present on our RPi CM4, where it
connects very slow to the internet from time to time. I've observed that
it takes anywhere from a couple of minutes up to 8 minutes. It typically
also disconnects from the internet after some time (up to 20 min after
connecting) before again trying to reconnect. I've sourced this issue
down to the version of the ModemManager.
Originally our CM4's had modemmanager 1.16.6-2~20.04.1 running where we
saw no issues, and the CM4 connected to the internet after around 20s.
After upgrading to modemmanager 1.18.6-1~ubuntu20.04.1 we're
experiencing this issue. I can consistently reproduce this issue by just
simply having a CM4 which has the 1.16 version, upgrade the modemmanager
apt to 1.18, and then just restart the CM4. The attached document
"modemmanager_logs" shows ModemManager logs, where the connection is
slow at connecting to the internet. I also have ModemManager logs from
when it connects->Disconnects->Connects, but I can only insert one
attachment to the bug report.
What I refer to when I evaluate if the CM4 has internet, is if the
NetworkManager reaches Connected-Global state.
Essentially I'm trying to create a script which will prepare a new CM4
with all the dependencies and stuff which is required to run our
software. Is there a way to force the 1.16 version of the modemmanager
to be installed on the CM4? Currently I only see version 1.18.6 and
1.12.8 available.
Additional info:
- Ubuntu 20.04
- modemmanager:
1.18.6-1~ubuntu20.04.1 (with issues)
1.16.6-2~20.04.1 (without issues)
