I see. Well it seems to me you've "customized" your system such that it would be hard for, at least me, to offer much advice. For example, I really don't know if you're using the previous method of controlling the network or using NetworkManager or a mixture. And, FWIW, I fail to appreciate the value of the customization. -- The key to getting good answers is to ask good questions. _______________________________________________ users mailing list -- users@lists.fedoraproject.org To unsubscribe send an email to users-le...@lists.fedoraproject.org Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/users@lists.fedoraproject.org
