Hi,
first of all, I'm happy that I got mobile broadband working under Linux
on my Toshiba Portege, using ModemManager and mmcli. The notebook has a
built-in SIM port with a Sierra mobile broadband device. On Linux (Crux)
I get an interface "wwp0s20u4c2i12" and connecting with mmcli
--simple-connect works well - at least the first time.
However, when I disconnect, and then (after some time) try to
re-connect, I frequently don't get a connection again. Whatever I do
results in a timeout. Neither disabling and re-enabling the modem nor
removing and reloading the kernel module helps; only after rebooting I
can get a connection again.
I append part of the debug output; when the problem arises, the log
starts reporting "unexpected messages". Could anybody have a look into it?
Thanks, Bernd
