Bug ID: 1104571 Summary: 3g 4g modem connects but no traffic possible Classification: openSUSE Product: openSUSE Distribution Version: Leap 15.0 Hardware: Other OS: Other Status: NEW Severity: Normal Priority: P5 - None Component: Network Assignee: bnc-team-screening@forge.provo.novell.com Reporter: dpbasti@wp.pl QA Contact: qa-bugs@suse.de Found By: --- Blocker: ---

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 100.101.44.240/30 dev wwan0 proto kernel scope link src 100.101.44.242 metric 700

and also the logs of netowork manager
