From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

If you're saying you started on Gnome, then dropped in another DE, you need to switch to an agnostic network manager if you were relying on Gnome's Desktop Network manager implementation probably.
If you're saying you booted a clean Fedora Cosmic LiveUSB and couldn't get WiFi working, you need to look at logs or run through some cli debugging to see what's up. Probably just Cosmic issues.
Edit: forgot about nmtui. You can use this to debug issues from the clinpretty simply if the desktop tools are failing.
I believe he should check his NM Status like this:
systemctl status NetworkManagerOr also check the logs dmesg o journalctl
Nah just to be clear, I tried to dual boot Fedora Cosmic Atomic and later Fedora Cosmic with Fedora Workstation.
Grub wasn't seeing my Fedora Workstation install anymore, so I don't think the Gnome network manager comes into account.
But I might be way out of my league as there is so much I don't understand.
Try using your CMOS' EFI boot manager and see if it sees both. If so, just skip Grub and use that.
