Bug ID: 431952
Summary: ModemManager takes over the active usb tether
connection and traffic stops
Product: plasma-nm
Version: 5.20.5
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: jgrul...@redhat.com
Reporter: michael.hm...@gmail.com
Target Milestone: ---
the active usb tethering connection stops, typical browser info then is: you
have no network connection
there is no clear way to reproduz it but seems to happen more often with a idle
connection, you read something and then want to go ahead and no connection, the
tray network icon changes then to the wireless icon
it often happens when I activate the tethering option on the cellphone before
the desktop is totally up and then it already comes up with the wireless icon
the only way to get it back is closing the tether connection on the cellphone
and reactivate it
workaround is deactivating the ModemManager
thanks
