When I was seeing this issue before I made the bios config change, I did notice that when the wifi and/or bluetooth died it'd need a hard power down and start up rather than a reboot to get it properly working.
To test your query I just rebooted three times in a row, wireless came up, authenticated and got an IP each time, bluetooth was also visible and available to be used (though, as I'm on the train, I have no bluetooth device on hand to actually test it with) whereas, usually if it were broken, wifi & bluetooth would not show as available in the gnome interface or the terminal. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1799988 Title: Missing wifi and bluetooth after sleep on XPS 9370 To manage notifications about this bug go to: https://bugs.launchpad.net/dell-sputnik/+bug/1799988/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
