From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Very helpful and enlightening comment, without this guidance I was lost.
You'll fit right in, 'round here.
e: saw you go it fixed, congrats. It's always DNS
If you try to ping 8.8.8.8 and it works, then try to ping google.com. if that doesn't work, it's your DNS resolver. I'm not an arch user, but on a lot of Linuxes, there's a nameserver setting somewhere that has come unset. Try to set it to the IP address of your home router, that may fix it. P.S. The guy who posted the "It's always DNS" shirt is right. I am buying that shirt.
Did you enable accept subnets or exit node?
Try doing a --reset --up and don't turn on any extra features.
I no longer have tailscale installed. i uninstalled it thinking that would fix it. I cannot reinstall it now because I can't cinnect to the internet.
I still am getting somw data transfer it looms like. I can see my upload and down load speed fluctuating. It just shows a yellow triangle by my ethernet icon and says "limited connection".
Did you reboot?
Yes the issue still arises
Tailscale edits /etc/resolv.conf, since your DNS isn't working start by making sure that file is how the archwiki suggests rather than what tailscale changes it to.
An uninstalled tailscale may still have left that file modified.
I run a personal dnsmasq just for dns resolving/routing. It integrates well with Networkmanager. Easy to work with and very reliable to have the DNS resolution and routing be handled by dnsmasq. Single command to reload NetworkManager which also reloads the integrated dnsmasq. I like it and it offers a lot of control for me. I hate having to use the hosts file for when I am connecting to labs via VPN with their own network. dnsmasq is way better at handling subdomains than the hosts file and it feels way more reliable than just hoping the minimal DNS routing system works properly.
