t2 mac, correct? see https://wiki.t2linux.org/guides/hybrid-graphics/#suspend-workaround for suspend. as for wifi, are you using brcmfmac? you can check with lspci -kk | grep -A 3 Network. you may also have to disable bluetooth, i've heard of it causing wifi issues.
I run Fedora Workstation on a 2012 MacBook Pro and enabling rpm fusion to get the Broadcom drivers was enough.
I had to repeat the operation once or twice in 3-4 years but otherwise it’s been smooth sailing.
I haven’t tried sleep mode though as I always turn off the computer.
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.
