Kubuntu 23.10 connects to wifi, but only after all other startup programs have run.
I’m just curious as to why that is. And what controls this startup behavior.
I’ve had to change some startup scripts for rclone, to wait until a network connection is present before starting. Other than that it’s not a problem.

Open the SVG and have a look at what’s happening during boot.
journalctl -b will give you some more info too. If you’re using grub to boot (probably in /boot/grub/grub.cfg), you can change the loglevel and add the udev option to get a bunch more info. Helped me with a random issue recently. Here’s mine for an example:
### BEGIN /etc/grub.d/10_linux ###
menuentry 'Arch Linux' --class arch --class gnu-linux --class gnu --class os $menuentry_id_option 'gnulinux-simple-a96b3354-70dd-45ed-8c6c-95171e9f1e82' {
load_video
set gfxpayload=keep
insmod gzio
insmod part_gpt
insmod ext2
search --no-floppy --fs-uuid --set=root a96b3354-70dd-45ed-8c6c-95171e9f1e82
echo 'Loading Linux linux ...'
linux /boot/vmlinuz-linux root=UUID=a96b3354-70dd-45ed-8c6c-95171e9f1e82 rw loglevel=3 udev.log-priority=debug
echo 'Loading initial ramdisk ...'
initrd /boot/amd-ucode.img /boot/initramfs-linux.img
}
FYI: /etc/grub.d/10_linux should not be edited directly for permanent changes since those changes get replaced when grub is updated.
Use /etc/default/grub for permanent changes.
True, but for this purpose it’s totally fine.
There’s also a big disclaimer at the top of the file:
cat grub.cfg
DO NOT EDIT THIS FILE
It is automatically generated by grub-mkconfig using templates
from /etc/grub.d and settings from /etc/default/grub
Wording could probably be less DOOM SHALL BEFALL YE, as long as you aren’t messing around and just adding logging it’s not an issue.
