Hi everyone, me again. I'm just having the weirdest bug I've ever had. I was watching youtube videos like any other sunday and then: no more internet. Just like that.
Almost.
None of my 4 browsers can connect to any site, my terminal can't update the system because it can't reach the repos, and so on but... Connman still shows that I'm correctly connected, systemctl shows absolutely no errors and... KDE-Connect still could easily and quickly as ever send a 2.3Gb file back and forth between Garuda and my phone? Notification sync is also working perfectly.

-> I tried disconnecting and reconnecting several times, I tried login in and out, I tried rebooting, shuting down, I tried mannually removing the ethernet cable and putting it back in... nothing seems to get my system back online and honestly I ran out of knowledge to solve this problem. Apart from the fact that... the system seems to be online '_'

The last weird thing is that this monday morning, I booted up and there it was: the internet again! Worked perfectly for about one hour and then, back to the same mysterious issue once again. It's just weird, I have no idea what's going on.

Just as aditional info, yes, my phone still can connect to the internet, so can my TV through cable, so can my secondary system in the same exact machine, in which I am right now (and therefore I had to retrieve an inxi-faz from a previous post of mine), so I really think this is a Garuda only issue.
I literally didn't mess up with anything, last time I updated was wednesday (and that was the wildest thing I did with my system all week long) and everything was working fine untill literally from a second to another it just wasn't.

All and any ideas are more than welcome '_'

Nope :slight_smile:

Try in terminal

ping -c 3 8.8.8.8

Have you tried with a different Ethernet cable?

No I didn't try another cable, but if it were the cable, shouldn't my secondary OS be unable to connect as well?

As for the ping, here is my result, even tho this time when I booted the internet seems to be okay again? If (and hopefully not when) the error occurs again, I'll repeat the operation and post the result of then.

His(?) intent (I assume) with that test to determine if "the internet" is working and it's a DNS issue (an internet service that converts web addresses into IP addresses).

It COULD be that the connection to and/or the DNS you're using is having issues. This can be changed in Garuda-Assistant. If you have the issue again and that ping works, try changing the DNS server (in settings tab).

Sorry, I skept that part of your checks.
Anyway, does the other OS connects always, and especially when Garuda doesn’t?
If not, maybe you could try another cable.
And if the other OS is windows, that’s a different story, I think, and it’s worth testing a different cable.

Yeah sounds like your DNS or route is botched that's all.

Alright, the internet seems stable for now, and I'm hoping it stays like so, but now I won't be able to stay at my desktop to be sure of it
.
But good thinking, maybe it's a DNS problem? If the problem happens again, I'll try changing it. From the Garuda assistant, any recommendations? I've seen there's a handful of options there and I have no idea what should be best

And, yes, filo, as I was working when the internet stopped today, I immediatly changed OSs and Pop! could connect with no problems at all. Also yesterday, as I assumed Garuda wouldn't be able to connect, I did all my late afternoon and night youtube watching and internet scrolling through Pop! and it didn't flinch xD

if it happens again check your route (yes just route in term) or just ping something external like fark.com. If you can ping things on your network but fark fails you can do a tracepath to see where things are dying. In theory you could just sudo dhclient -r ; sudo dhclient and see if that smartens it up when it happens again so long as a ping to the router succeeds.

Alright, so I just sat down and started working again, and again the same problem popped up my face.
Second thing I did was try and change the DNS at the Garuda Assistant and, simple like that, everything was back online!
Before changing the DNS I tried the ping 3 8.8.8.8 again and the result was the same, I tried pinging wikipedia and it returned as unknown. After changing it, not only wikipedia returned to me and endless list of 64bit packages xD but it also got my browser back to normal function!
Thanks everyone for all the help, specially @anon26187667 for being the first one to spot that it could be a dns kinda of thing.

11

I just have one last thing to ask, I never really picked a DNS in my life before, and even knowing that the Garuda team wouldn't put anything as a preset on the settings if it wasn't near perfection, I still have no idea what kind of DNS should I choose
Can anyone give me a hint?

Try switching to cloudflare for your DNS (IP address 1.1.1.1).

I was going to suggest this a bit back when I caught your thread, but you said things were working again.

try 1.1.1.1 which is cloudflare :smiley:

I just picked up on and clarified what SGS was getting at :woman_shrugging:

I've used OpenDNS for years and years. Reliable enough and easily memorable IP addresses :+1:

E2A: Okay, so their IP isn't as easily memorable as Cloudflare apparently :smiley:

I've always used opendns (before running my own) but my vote is switch between so it skews data collection externally :wink:
