3G D-Link DWM-157 Modem Install on Ubuntu 12.04

I am running the 157 on Mint 16 now, working fine, but the install not smooth: installed the .deb no problem, nothing happened though- no detection by network manager. Had to unplug eth0 and reboot- then Network manager detected it.

The documentaion for this device is close to non-existant, playing around I discovered a more elegant solution (but still not perfect):

The software installs a script: 3g_connect.sh

Run 3g_connect.sh form the terminal:

3g_connect.sh 003:010

ie the arguement to 3g_connect.sh is the BUS:DEVICE pair from you post:

my USB-device is found ("Bus 003 Device 010: ID 2001:a707 D-Link Corp.")

Note: The 3g_connect.sh script should be run as root for it to work, but running it as a normal user did force Network manager to detect the dongle- and I could then use Network manager to manage it- which I prefer).

Hope this helps.
