No Wifi Network

Hello, my laptop slept for about an hour and now I don't have any wifi connection. When I open network manager there is no Wifi to which I can connect. I tried to reboot and restore a backup from timeshift.

-My wifi on mobile works

Now I rebooted my laptop and I got black screen.

Maybe try to boot removing quiet splash from the boot parameters in the grub, to see if it stops at a specific point.
Also try booting to a TTY and update and/or startx.
In general, see

How can I get tty log?
When I write TTY into console it writes /dev/tty2 when I cat it, it is blank.
I can't update my laptop when I haven't internet connection.

To log to tty, when you are in the grub line that you use, press button E go at the end of the line starting with linux and add a 3 at the end (with a space before...), then CTRL+x
If you can use an ethernet connection maybe try to update.
Anyway try to enter startx and check relevant error messages.

Edit:
Ops sorry you probably already booted to a TTY

Maybe this could be also your problem.
When in TTY try to free some space.
For example the pacman cache with sudo pacman -Sc.
Anything you can do.
Maybe also balooctl purge could free up some space

Well spotted.
Though also, thanks to naman for sorting out the formatting (which had prevented me from looking too close)
