Right, I’m usually able to solve these issues by research but this time I’m stumped.
I’m running on an install that has worked fine, with little to no config other than some ricing. Recently updated through pacman as normal, didn’t pay much attention to what was actually updated (as normal), rebooted, and now I’m stuck with an issue, and I don’t know where to look for the source.
Essentially, I am able to connect to google.com (most of the time), but anything else is up to chance. When I ping a site, it’s able to resolve the domain (except when it doesn’t), but then I get “Destination net unreachable”. Journalctl is all green, no errors, no out of ordinary messages.
Things I Have Found:
- When I reboot, it works fine, for a little bit, and then it starts losing connections to things randomly.
- When I mess with wifi settings (turn it off and back on, turn off ipv6, change dns, switch between wifi) it sometimes makes it work, for a bit, and then it stops again.
- All other devices on the network function fine, its not the ISP, its not a firewall, its something local to this computer
- Its most likely not a DNS issue of any kind, although I usually can’t even ping 8.8.8.8, or 1.1.1.1 (gets resolved, get “destination net unreachable”)
- It’s consistently inconsistent on what sites its able to reach, and which it can’t, except for google, it can usually reach google. I’m wondering if this has something to do with ISP/DNS caching.
My main issue right now, is I don’t really know where to look to find the problem. I have all these symptoms but no diagnoses.
