No internet after last update, but wifi works

[FullScale4Me]

ping 1.1.1.1 says: "ping: sendmsg: operation not permitted. From 192.x.x.x icmp_seq=4 Destination Port Unreachable"

I can't reach the router from the browser from the device. But the router is reachable from every other device in the network.

Thanks for helping me out :)

Is there a Firewall or VPN enabled on this PC? Even though this message implies the remote device has refused ICMP type packets, it could be an intermediate one like a firewall/VP/Router setting.

Can other PCs in your local setup ping 1.1.1.1 ?

In the Uncomplicated Firewall, make sure that ports 67 and 68 are not blocked (MX User Manual 4.5.1).

If present a VPN might require a command similar to:

Code: Select all

nordvpn set killswitch disable

If you still have mx-updater on your i3 desktop, you could look at "History" in its right-click menu--if not, the history is in a log file on your machine. That way we can see what was updated two days ago.

A little update:

I've booted with systemd this morning (see selected kernel on picture) and internet worked out of the nowhere. I didn't know why it worked out of the nowhere, but if I restarted the system and booted without systemd, internet didn't work again.

Is there any explanation why?

Please post the QSI from a live session so we can compare it to the one from your install.

I will do it in the evening after I am back at home (and if the issue wasn't solved yet)

What was the interval between the update two days ago and the previous one?

Sorry, I don't know this. I do updates every 3-4 weeks, sometimes 1-3 months. Not really a consistent task and I am afraid something will not work after updating, that's why I don't like to do it often. Or is it even because I don't do it often?

The only VPN I am using is deactivated.

Other devices can ping everything.

There is no mx-updater installed and I can't find it. This tool sounds somehow useful, why isn't it there anymore?

I wanted to see if we could track down the specific update that caused the problem, but with such a sporadic update method it's almost a Herculean task.

Based on the age of your CPU, your WiFi card is ten years old. Either the SysV init driver has been dropped from the kernel due to age or the newest driver / firmware is SystemD only at this time.

Sometimes it likes to mysteriously vanish which is why the MX developers have "Re-enable MX Updater icon even if no updates available" in the Whisker menu listed under "MX Updater", click on it and you will see it reappear in the panel.

We have seen over and over that "some" VPN's do not fully disengage.. some times. Since you had internet at one start, but not at another...I would suggest uninstalling your VPN while you are testing - as a test.

And which VPN are you using?

+1 to this not being fully addressed.

The simple action of disconnecting a VPN in many cases does NOT fully divest the PC of it's overall [filtering/routing influence on network connectivity.

Check with “lsattr /etc/resolv.conf”

If there is an “i” in the result, i.e. “----i---------e------- /etc/resolv.conf”, enter “sudo chattr -i /etc/resolv.conf”. Maybe a reboot is needed.

I use a VPN. Occasionally I have the same situation. I don't know the reason. The only way I can get it working again. Hope this helps.

QSI also allows for viewing and copying the apt history.
