Hello, I have a laptop Lenovo Y720 with Intel 8265 wifi adapter.

As I installed fedora, there is wifi switch in upright screen corner, which says WiFi Off. Then I click it to turn WiFi on, but when I open that small window in corner, the button still says WiFi Off... I suspect that I don't have appropriate drivers for this WiFi card.

I downloaded driver (package iwlwifi-8265-ucode-22.361476.0.tgz) from here https://www.intel.com/content/www/us/...

Inside the package there is .ucode file (I think that's the actual driver), license and readme files. I was searching the Internet for days trying to install driver, only thing I could do was paste .ucode file in /lib/firmware/ but then event after rebooting system WiFi won't work.

As I was using windows usually, and had tried Fedora earlier but on different machine with no issues, I'm unfamiliar to such problems. I expect something similar to windows drivers - download - dbl click - next next next.. Installed. Basically I don't even understand what is my situation now and what and how should I do. I don't know how to update kernel, modify kernel or some configurations. Also why I should update kernel if I just installed feroda latest version 27. I would appreciate if someone could help me solve this issue by little steps, because I wanted to use fedora and not Ubuntu / Mint etc... So far I tried lspci and my wifi card is listed there.

Can you explain more broadly what my further steps would be to make iwlwifi to load the .ucode file? When does it load that firmware ( at what point, event ).

I'm not 100% sure how it works but when you load the iwlwifi module with modprobe iwlwifi it will know which firmware it needs to read for the specific card.

The wifi card is supported by Fedora; Check all switch in your laptop; maybe you need power on.... if not then you can update to current firmware...

Download the updated firmware

1) wget -c https://git.kernel.org/pub/scm/linux/kernel/git/iwlwifi/linux-firmware.git/snapshot/linux-firmware-iwlwifi-fw-2017-11-15.tar.gz

Extract

2) tar xmzvf linux-firmware-iwlwifi-fw-2017-11-15.tar.gz -C $PWD

Make build directories

3) mkdir -p $HOME/iwlwifi

Now the build

4) pushd linux-firmware-iwlwifi-fw-2017-11-15/

5) make -j 4 DESTDIR=$HOME/iwlwifi   FIRMWAREDIR=/usr/lib/firmware install

6) rm -f "$HOME/iwlwifi/usr/lib/firmware/"{Makefile,README,configure,GPL-3}

7) install -d "$HOME/iwlwifi/usr/share/licenses/linux-firmware"

8) install -Dm644 LICEN* WHENCE "$HOME/iwlwifi/usr/share/licenses/linux-firmware/"

Trigger a microcode reload for configurations not using early updates

9) install -d "$HOME/iwlwifi/usr/lib/tmpfiles.d"

10) echo 'w /sys/devices/system/cpu/microcode/reload - - - - 1'  > "$HOME/iwlwifi/usr/lib/tmpfiles.d/linux-firmware.conf"

11) popd

Now the installation

a) pushd $HOME/iwlwifi

b) su

c) cp -nr * /

d) popd

Now reboot! and cross fingers!

So... Can anyone help me? I still can't solve this problem. I don't have wifi on my fedora. I think I'll just have to try differend distributions but I really wanted to use fedore because it is not that popular.

Patience is a virtue. Here we all help voluntarily; Now if you want support you are wrong (Pay for it.) Good trip, if you plan to change distribution. Threatens to leave is childish..
