No internet connection (both ethernet & wifi) after 22.04 upgrade

[stinktier2]

I FEEL REALLY STUPID!


I just discovered that the Wired connection DOES work – the cable was just not plugged into the router! (It must have slipped off some time in the past, the plug doesn't lock...)

However, the wifi/ethernet connection still doesn't work – the laptop does not connect. The connection is labeled with the lock icon, although it is open/password-free (what my smartphone calls "Enhanced Open"). When I create a wifi hotspot with my phone, the laptop connects to it and has proper internet. So what's happening with the regular WLAN?

You know it's always the simple things I over look when helping, but good find.
Will you now please run the syystem-info script found in my signature.
Please include the link it gives you here in your thread, and run it with the "--details" flag. ie:

wget -N -t 5 -T 10 https://github.com/UbuntuForums/system-info/raw/main/system-info && \
chmod +x system-info && \
./system-info ''details

This way I'll have most of what I/we need to see first before proceeding.
BTW since you secured the the connection, have you rebooted yet? without the Hot Spot active.

I have rebooted the laptop a couple of times. The hotspot was active only for a short time. Still cannot connect to this specific wireless connection.

I'm looking at now, but I still do not see a net device.
I'm on Arch for a few hours today I have obligations to fulfill first, but in the meantime will you show this please:

sudo apt-get install --reinstall network-manager

EDIT Also show this as well:

sudo apt install --reinstall wpasupplicant

I'll be back.

Take your time. This is no longer critical. Annoying, yes, but no longer a panic-inducing issue.

Did both reinstalls and rebooted, no change at all in the behaviour re: wireless.

Annoying indeed, what shows with:

rfkill list all

Also is this your provider: https://freifunk.net/en/how-to-join/

This is correct. I have a second router with custom "Freifunk" firmware that is connected to the one of my regular provider. The Freifunk router provides this free, anonymous internet for me and anybody who wants to connect.

Well wlan is not blocked so you might have to ask "Freifunk" for help here, as I know nothing about them or their firmware.
And just a thought, have you rebooted the router yet?

Try

sudo ufw allow 53
sudo ufw allow 67
sudo ufw default allow FORWARD

[praseodym]

sudo rfkill unblock all
rfkill list

Remove all wired profiles from the NWM and reboot
