Connection with Vodafone (ZTE) K3806-Z USB HSPA Modem is not working
Last modified: 2020-11-12 14:31:55 UTC
I can't connect with my Vodafone (ZTE) K3806-Z HSPA USB modem using NetworkManager's Mobile Broadband feature, although I can connect with this modem using Sakis3G 0.2.0e script. In NetworkManager the connection is configured properly (user name, password, APN, etc.), at least with Sakis3G the same connection configuration works OK. Although with Sakis3G I needed to tweak resolv.conf by adding the IPs of the DNSes of the network provider, but with such a resolv.conf connection with NetworkManager still doesn't work. The symptom is the following. Once I plug in the modem, NetworkManager's "SIM PIN Unlock Required" message appears, I enter the PIN. I set the connection not to connect automatically therefore I click on the configured broadband connection in the menu (from the Indicator area of the panel) requesting to connect using that. Within a second I receive the "GSM network. You are now registered on the home network." notification then after an other second I receive the "Connection Established" message for the connection. I get an IP address for the interface usb0, but seemingly can't reach anything outside. The resolv.conf contains the same information that is working when connected with Sakis3G. Please find below some details of the environment and the issue.

bugzilla.gnome.org is being shut down in favor of a GitLab instance. We are closing all old bug reports and feature requests in GNOME Bugzilla which have not seen updates for a long time. If you still use NetworkManager and if you still see this bug / want this feature in a recent and supported version of NetworkManager, then please feel free to report it at https://gitlab.freedesktop.org/NetworkManager/NetworkManager/-/issues/ Thank you for creating this report and we are sorry it could not be implemented (workforce and time is unfortunately limited).
