Hi
I have a dual boot Opensuse Leap15/Ubuntu 18.04 system on HP G2 laptop with 4g
modem.
In ubuntu all works fine
In opensuse I added the connection in KDE - all default options -my carrier was
listed.
The modem get's connected - receives default route, IP assignment, DNS
but for some reason no data is being sent/received - not even a simple
ping 8.8.8.8 works
here are the params
ip addr show
5: wwan0: <BROADCAST,MULTICAST,NOARP,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast
state UNKNOWN group default qlen 1000
link/ether 7a:c6:53:8c:bf:03 brd ff:ff:ff:ff:ff:ff
inet 100.101.44.242/30 brd 100.101.44.243 scope global noprefixroute wwan0
valid_lft forever preferred_lft forever
ip route show
default via 100.101.44.241 dev wwan0 proto static metric 20700

and also the logs of netowork manager
