Thu Oct 30 21:06:19 2014 daemon.notice netifd: Interface 'wan' is now down
and no connection, then:
config interface 'wan'
option ifname 'wwan0'
option proto 'ncm'
option apn 'opengate'
option device '/dev/ttyUSB1' (this is "correct" port when
using Oskari Rauta's original code, running on main router)

failed: Unknown error
Also behaviour is quite similar to mine previous email, Huawei's light
stays lit, but no wwan0 etc available...
Also, if I then run first "ifconfig wwan0 up" and then "dhclient -i
wwan0" I get IP for wwan0 and internet works! can ping and use SSH to
remote location... So this must be something small typo or so
somewhere deep in scripts?!
