Name resolution failure
I'm having troubles connecting my laptop with the internet. I can ping my router and can connect to the web interface. Connection with my phone works well (mobile data turned off) so internet connection is not an issue. Got to be something with my machine. I updated last night. I'm using NetworkManager with default setting to manage my connections. Really not sure what to look for. THX Frank

Hi Frank, as you wrote in the subject, it sounds like a problem with DNS. Try running dig archlinux.org (from the bind package) If it fails, your DNS is not working. Check the address of your dns server in /etc/resolve.conf - it’s probably a loopback ip to a DNS cache. You can check which one with sudo lsof -i :53 then you should check for its logs and maybe try to restart it - though you probably already rebooted (if not, try that first). Best, tippfehlr
The entries in resolve.conf looked good. I can look them up in who is, however cannot ping them. So changing the nameserver entries does the trick. Am 14. Januar 2026 21:09:04 MEZ schrieb tippfehlr <tippfehlr@tippfehlr.dev>:
