Bug Description
Upon a "clean" upgrade (No software installed except base system from ISO, then upgrade) from 16.04 LTS -> 16.10 -> 17.04 on a Dell 9360, Network Manager fails to detect wiFi device in 17.04 Zesty after a few boots/updates. Wifi works initially. I apply Zesty updates. I autoremoved some packages. I reboot. Wifi is killed. I cannot report the bug using "ubuntu-bug" because I have no network connectivity.
The wifi device was not detected despite re-enabling Dell's Xenial repos after upgrades.
I have a Dell DA200 adapter USB-C to HDMI/VGA/
I subsequently had to revert back to 16.04 LTS with a clean install to report the bug. I'm not so familiar with what the Dell repos provide for Xenial. Do they provide the drivers needed for the wifi? Or is that supplied through the kernel? Could the autoremove have caused the wifi drivers to be removed?

Both the onboard wifi and ethernet through the Dell DA200 USB-C adapter work properly in 16.04 LTS running the following kernel:
