This problem did not happen with F23 installations. So, unless this bug recently came in, then I don't know why it worked just fine with the old setup. I had issues with F23 doing this on occasion. I believe it was a point where NM had been updated but nm-applet hadn't caught up yet. I don't recall exactly. Had similar issues with bluetooth (those were definitely dbus-related). > Btw, assuming that this is a bug, where should I file it? Before that, I should perhaps make sure and look at the logs that you talked about here? Which logs should I check? I'd assume the bug should be filed against both NM and nm-applet since it's some sort of mis-interaction between them and it's not clear whose mechanism should be followed. As far as logs, I'd check both dmesg and the system log for things containing "network". ---------------------------------------------------------------------- - Rick Stevens, Systems Engineer, AllDigital ricks@xxxxxxxxxxxxxx - - AIM/Skype: therps2 ICQ: 226437340 Yahoo: origrps2 - - - - IGNORE that man behind the keyboard! - - - The Wizard of OS - ---------------------------------------------------------------------- -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://lists.fedoraproject.org/admin/lists/users@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
