[SOLVED] Huawei MS2131

[rigers]

Hi,

I am trying to connect a Huawei MS2131 dongle to a Raspberry Pi running Arch Linux ARM. It "seems" that the device connects but I can't get an IP. The cell module shows online from the cell service. I've gotten it to work on a similar setup before but can't seem to be able to do it again. Any insight would be appreciated.

The output from nmcli is as follows:

dmesg shows the following

ifconfig has the following output. I've tried setting wwan0 UP and DOWN multiple times to no success.

Solved by updating system, uninstalling NetworkManager, ModemManager, and usb_modeswitch. Reinstalled them and it works. I suspect the system update made it work, but I don't know.

mmcli output now reads
$this->bbcode_second_pass_code('', '$ mmcli -m 0

The primary port changed from ttyUSB0 to ttyUSB2
