USING LINUX WITH THE L4G2D RADIO
To avoid making wwan0 the default gateway for all IP traffic open /etc/udhcpc/default.script, look for a line
containing "route add default", and edit/comment out accordingly.
Confirm the wwan0 network interface is configured and test network connection:
$ ifconfig wwan0
wwan0: flags=4305<UP,POINTOPOINT,RUNNING,NOARP,MULTICAST>
inet 25.33.152.134
