Ubuntu 22.04.2 LTS I can connect to my router, but internet does not work after the last update.

Ping 8.8.8.8 gives me (8.8.8.8) 56(84 bytes of data.

I try inconfig but says I do not have net-tools installed. I can not download anything as I do not have internet.

I have also rebooted several times. tried unplugging ethernet, plugging back in (obviously works though as it connects to my router via ethernet and my other computer is connect via the same line in from a split box)

I newer to Ubuntu so I will try to answer your questions as best as possible and edit this question with updated info as I learn.

If someone has suggestions for paid support I am happy with that too.

Thank you!

When you were configuring Ubuntu did you input the network settings manually or automatically? Possibly try a reinstall and do automatic network. I was having a similar problem and was able to use automatic to install network manager and havent been having any problems from there with network connectivity.

This sounds like a DNS problem. And since you mentioned using a VPN, it could possibly be related to that.

Does this help?

Did the latest apt update to Ubuntu 22.04 running on an XPS 9320 Now lsb_release -a shows Ubuntu 22.04.4 LTS

I normally use a wired connection only, I turn off WIFI. After this update the wired connection stopped working, by WIFI did. Found this: Ethernet connection disabled in Ubuntu 22.04 OS I added except:type:ethernet to /usr/lib/NetworkManager/conf.d/10-globally-managed-devices.conf as they recommened.

Restarted the service. No joy.

Rebooted. No joy.

dmesg showd issues with DKMS. Uninstalled VirtualBox. Got the kernel to recompile. Rebooted. No joy.

All of a sudden the RaspberryPI NAS I had connected to it stopped working too.

So rebooted. No joy.

Finally I did a hard reboot. Power off and power on again. Rebooted the RPI and drives connected to it.

It all came back up. I had to reset the SSL for the RPI but everything else came up:

  • connecting to the drives works fine
  • wired connection works fine

Not sure why I had to do a hard reboot vs a "sudo reboot". But it worked.
