Trying to connect to internet through K5150 usb modem on raspbian buster(last build from raspberry, September).
On windows it is connecting when it is plugged in.
Here is trying to connect but not receiving tx and it is the stand by icon: ↑↓ one arrow blue, one arrow grey.
When tried manual:
sudo ip link set wwan0 down
and:
sudo ip link set wwan0 up
sleep 65
ifconfig wwan0
route -n
