I have a Huawei E3531 3G dongle (which works fine on Ubuntu 14.04, right out of the box). However, it registers as an USB-Ethernet adapter and I can't view any signal strength or other connection information except by visiting the dongle's internal webpage at 192.168.8.1. Can this dongle also be used as a ttyUSBx modem device so it works properly with network-manager?
Thanks!
Florian
