After installing linux-headers-4.16.0-041600rc4_4.16.0-041600rc4.201803041930_all.deb , linux-headers-4.16.0-041600rc4-generic_4.16.0-041600rc4.201803041930_amd64.deb and linux-image-4.16.0-041600rc4-generic_4.16.0-041600rc4.201803041930_amd64.deb from http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.16-rc4/ and booting 4.16.0-041600rc4-generic I have eth0. So, apparently this is fixed in later kernel versions.
I am still encountering https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1752081 "platform regulatory.0: Direct firmware load for regulatory.db failed with error -2" but wireless now works nevertheless. I originally reported this bug for the wired Ethernet interface because I wasn't sure if that other bug was causing wireless to not work. Now I'm thinking this same bug was probably making wireless not work either. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1754911 Title: b44 Ethernet driver not working in Linux 4.15 on Inspiron 6400 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1754911/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
