Can’t find my local network and certain websites after update

hey folks! happy new year!

after the update on my manjaro machine, I’m unable to connect to any websites (except google’s products) and i’m unable to connect to my pi pver ssh nor can I access my router.

I use my raspberry pi as a dns server, btw.

How can I fix this?

Edit: a few things I find odd:

  • ip route show doesn’t return anything
  • ifconfig and nmcli show my connections with only ipv6. no local ipv4
  • i read somewhere about using dkms to update the network driver, but dkms status shows empty.

Hello @gui42,

do you use ethernet or wifi to access your local network?

Do you use ip-adresses or device-names to access other devices in the network?

What is the output from this command:

nmcli | cat

If you mask your ip adresses in the output, mask it that way that someone can differ/match it.

Hey, I eddited my question with some new info that I could gather from browsing other peoples issues, and troubleshooting on my own. And also, this is the output of nmcli. The dns server changed after the update. But I can’t access the server via ssh so I think changing the configuration won’t do much :confused:

Have you tried to set ipv4 settings in your networkmanager by hand?

… and do you use DHCP in your network for your machine?

by networkmanager you mean nmcli, or on my router’s settings? And yes, i do use my isp’s router DHCP server to hand out ips to specifict devices.

By network manager I mean the software in your manjaro machine. You can use nmcli, nmtui or a ‘right-click’ on your networksymbol in your taskbar. :grinning:

Well. Found the problem here. It was one of those times when two things happen an the same time and I only looked at one. Together with the update, something started failing with my isp’s router, messing up the DHCP workings. @kisun suggestions helped me see that. :smiley: Thank you!! :smiley:

You are welcome. :grinning:
