Hi,
my laptop has a built-in GSM-module that has been working all the time and providing connectivity over mobilephone network. I use it only rarely and realized a while ago that it always fails to connect to the network now. some update must have changed something.
hardware: Sierra Wireless MC 8305 (lsusb: Bus 002 Device 004: ID 1199:9011 Sierra Wireless, Inc.)
kernel options:
| Code: | CONFIG_USB_SERIAL=m
CONFIG_USB_SERIAL_GENERIC=y
CONFIG_USB_SERIAL_MXUPORT=m
CONFIG_USB_SERIAL_QCAUX=m
CONFIG_USB_SERIAL_QUALCOMM=m
CONFIG_USB_SERIAL_SIERRAWIRELESS=m
CONFIG_USB_SERIAL_WWAN=m
CONFIG_USB_SERIAL_OPTION=m |
kernel modules:
| Code: | box linux # lsmod

so it seems the modem is still working and the correct modules are loaded automatically. also MMCLI agrees on that:

but whenever I try to connect via network manager, it fails to do so. here is the log what happens when I activate the 3G modem (including attempt to connect to my provider with the settings that had been working all the time):

I should mention that networkmanager also does not show any signal strength info. I searched the forums and google, without success. can anybody help me or has an idea where else to look?
thank you!
cheers,

Hi,
I had the same issue with my EM7455 after upgrading my kernel from 4.9.x to >=4.12.
They had been changes in the kernel modules. To fix it you need to install last version of modemmanager (1.6.10) to fix it (i also upgraded some dependencies).
I made an ebuild if you want to use it.
Hope it fixes it for you too. |

hi and thank you for the tip.
I'll wait til 1.6.10 is in the portage tree and test it here. |
