I have been trying to connect to the Internet with this Huawei E3372h modem for a couple of days now. I have tried everything from
networkmanager but everything fails.
ifconfig shows a
wwan0 network when the modem is connected.
wwan0 Link encap:Ethernet HWaddr 36:3a:ff:28:b4:51 inet6 addr: fe80::de3:879:29a5:e625/64 Scope:Link UP BROADCAST RUNNING NOARP MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:20 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 B) TX bytes:4408 (4.3 KiB)
If I try to connect to it , this is what I get
root@raspberrypi:/home/pi# sudo ifup wwan0 wwan-helper: Unsupported WWAN device: 12d1:157c run-parts: /etc/network/if-pre-up.d/local-wwan-helper exited with return code 1 Failed to bring up wwan0.
ls /dev/ also shows a
cdc-wdm0 device (but no
ttyUSBx device) . when I try to connect to it , this is what I get:
root@raspberrypi:/home/pi# sudo qmi-network /dev/cdc-wdm0 start Loading profile... APN: airtelgprs.com Starting network with 'qmicli -d /dev/cdc-wdm0 --wds-start-network=airtelgprs.com --client-no-release-cid'... error: couldn't create client for the 'wds' service: CID allocation failed in the CTL client: Transaction timed out error: network start failed, client not allocated
I am starting to doubt , the problem has go to do with the firmware of this device . Because , It works without any manual configuration when connected to a windows PC and on an Ubuntu. It just doesn't work with the Pi . What am I doing wrong? Should I change the firmware or something? Any solutions?
