I tried on Vostro 3555, Ethernet works fine after disabling wifi by clicking nm-applet or hotkey Fn+F2
It seems 3555 is not affected by this bug. I think the first information I need is the status LED on switch hub is on or off. In the mean time I will read how dell-wmi shutdown wifi. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/836885 Title: [Vostro 3550] Ethernet nonfuctional after wifi disabled To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/836885/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
