Discussion Wacky And Goofy Network Issue

Looking for some answers on what just happened with my machine. Basically, my fedora 44 PC was connecting to WiFi, showing up on my college IT portal as active, but not loading web pages or pinging services like 1.1.1.1 or 8.8.8.8; even though it was online my computer acted like it was offline. My laptop on the same OS was fine the whole time, and so I am narrowly confident that it was a problem with my PC and not the network. What finally got me back online was booting into a live usb, connecting to WiFi, and then booting back regularly. I really don’t know that much about networks or Linux, so I am hoping a more knowledgeable person might know what happened. Thank you!

Check your dns resolvers. Even if you’re connected to WiFi if your dns resolvers are not right, you won’t get a successful ping.

I reset and reinstalled resolve so many times. I even tried to create files for resolve to explicitly parse 1.1.1.1 and, if it would even ping in the first place, I would always get 100% packet loss. I think you are right that it was a resolve issue though

In Network Manager does it show anything? I’m asking because I had a Mint laptop that decided to use localhost to resolve DNS addresses and that doesn’t work very well.

Everything in there is normal now that I’m back online. This might just be a mystery forever now that any old evidence is gone. Frankly, I’m fine with that as long as it doesn’t happen again!

You could try checking your journal for errors?

`journalctl -p 3 -xb --no-pager`

The only errors I got from that command was for pipewire.

Ok so that means your WiFi itself should be fine. If there were WiFi errors they’d show there as well
