EDIT: forgot to add that the wifi networks all appear fine and connect (network name appears in the settings and connects successfully, just no network access no matter the interface)

EDIT 2: I did not really feel like troubleshooting my computer all day as I had kind of soft-bricked it by downgrading the kernel, and it didn’t boot. I felt it was a bit too far gone for me and like I said I didn’t want to spend the day fixing it. Anyways I had a separate /home so it was all fine. I installed PopOS as a (not so) temporary solution. Ill probably end up reinstalling Arch or something a bit more up to date soon enough. Thanks everyone for trying to help me!!

Hey there, I’m looking for some help with my Arch system that I updated today.

So a little context here: today, I updated my system with the usual -Syu. However after the update I kept getting pop ups that told me my LAN connection was not working or something ( I use gnome). Wifi was still working.

Now, I since rebooted in hopes the popups would go away (in a sense, they did…), I do not have any access to the internet, I tried everything I can think of (wifi only, wired only, usb tethering with my phone) but nothing works. I still get the wired icon in gnome even though the cable is unplugged.

I am having trouble finding help with the Reddit blackout (convenient timing lol) and it is pretty hard for me to attach logs and such since my computer has no network access at all, I’m relying 100% on my phone…

Any help is appreciated 🙂

    Sure thing, mind you post some specs like output of ip a, and ip route show? And what network manager do you use?

    Besides what the other comment said, the output of lspci related to network cards might be useful.

    Also looking at dmesg for errors could provide some insight. Although not having any network at all seems weird, if it was one card or another it would be one thing, but all network being down is weird.

    Have you checked if you have local connectivity? e.g. connecting to your router vía web browser. Also you should try pinging something by IP and by url, e.g. ping 8.8.8.8 and ping google.com if the first works but the second doesn’t it might be a DNS problem.

    So, you worked around it.

    If you run into it again here’s my “playbook” on checking network connectivity “from the bottom up” so I usually go:

    1. Check the “physical” connection. (In your case “is the wifi connected”
    2. Check if you have an IP (ip a)
    3. Check if you can ping your IP (just to be sure the network stack is working)
    4. Check if you can ping your router (usually the IP is 192.168.X.1 or .100 where X is the same as in your computers IP)
    5. Check if you can ping an IP “on the Internet” like 1.1.1.1
    6. Check if you can resolve names (ping something by domain like “google.com”)

    If all that works you got “internet” if one of these steps fail you know better where to debug.
