Arch Linux system won't connect to the network/internet
Arch Linux system won't connect to the network/internet
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, andip route show? And what network manager do you use?Hey, here they are! Nothing too unusual except for IP a, (I suspect this is due to network manager not starting and kicking me out to my login prompt) and everything worked before that update
Network Manager will never drop you to a CLI, even on catastrophical failure it just dies, you seem to have a larger problem.
Also try the
ip link showcommand to list the interfaces, since you have no interfaces connected to any network they don't show on ip addresses on your screen. If you don't have a GUI you'll need to connect manually, same way you did during installation (although I would suggest going with Ethernet since the packages needed for connecting to wireless easily from CLI are not installed by default from what I remember).Hi, I wanted to tell you thanks for your help, I decided it would have been too much trouble and just decided to nuke my arch install, I had a separate /home partition so I just installed PopOS as a maybe not so temporary replacement until I do a clean install. Anyways, thanks for the help!
ip ashows no interface exceptlo.what is the output of
lspci -v -s 05:00.0andlspci -v -s 06:00.0?Hi, I wanted to tell you thanks for your help, I decided it would have been too much trouble and just decided to nuke my arch install, I had a separate /home partition so I just installed PopOS as a maybe not so temporary replacement until I do a clean install.

You are welcome.
However, I suspect it's possibly a system corruption. So check your memory and hard drive to make sure they are OK before using your PC again.
And consider using btrfs, you can take snapshots before updating packages and restore them in case of package corruption.
Haha, funny you say that, I was using BRTFS, but I never bothered to make any snapshot lol. My lazyness caught me. As for the system corruption, I think its pretty unlikely, the PC is running just fine now, and it was running perfectly fine the day before and under Windows in between reboots. The only part that had no network was my arch install
There is also a possibility of system corruption. Can you post the output of this command as well?
_tmp=$(mktemp) && pacman -Qkk 2>&1 | grep -v '0 altered' > $_tmp && less < $_tmp
