No network Device Data found (LAN)

Last night I updated my machine and turned it off. This morning when I booted up I had no network via LAN. after hooking up a Wi-Fi dongle. I got this inxi

can anyone help?

Hi @Darvance,

looks like a loose contact at the PCI-Card or LAN as been disabled in the UEFI or the LAN Port died somehow.

Did you try booting a Manjaro Install Disk and checked if there is the same problem?

Which device was there? Maybe the updated kernel is not compiled with the module you need? Please try another Kernel. linux54 is the LTS one.

Hey @megavolt,

I ran the manjaro boot disk I use with the same result

And I checked my UEFI settings.

My PC has been giving me problems for a while now that is why I usually leave it on because if I turn it off I need to unplug it for a bit before it turns back on. so your other idea about a loose contact seems more viable atm.

10 to 1 the LAN chip died. I assume it’s a built in device to the mobo. When a device no longer shows in lspci or inxi -N, which also uses lspci in part, it means the device is dead, and there is nothing to detect, basically speaking. If it’s a pci card, you can always try reseating it to see if it’s a bad contact, but if it’s a built in, it’s dead. You really don’t need to reboot or boot to livecd in this scenario, if the hardware isn’t there and working, it’s not there and working. Rebooting etc would be more relevant if it’s a driver issue, but the hardware device not showing at all means it’s dead, so it’s not a driver issue. In terms of mobo diagnostics, this is one of the easier things to diagnose. Note that some board devices (audio, graphics usually) permit being disabled in bios/uefi, but they aren’t going to just disable themselves one start to the next. There’s a less common scenario where the chip is dying, but not dead, and works intermittently, but it’s still basically dead for all practical purposes.

from your other comments, it sounds like your board in general is dying, maybe failing capacitors? you can tell by opening the case and looking at the capacitors around the cpu, if they are not solid caps, and if their tops are bulging out, you can just toss the board, it’s basically dead.

Thanks for the information. I expected that it would stop working soon given all the faults I have been having. This just confirms it.
