Ethernet not working despite it working using the same driver on the Live install

On my PC I’ve used with Manjaro for a few months beforehand Internet was working all the time but since today it stopped working both on Ethernet and Wifi.

My inxi -Nazy output is:

Network:
  Device-1: Intel Ethernet I219-V vendor: Micro-Star MSI driver: e1000e 
  v: kernel port: f000 bus-ID: 00:1f.6 chip-ID: 8086:15b8 class-ID: 0200 
  Device-2: Intel Wireless 8260 driver: iwlwifi v: kernel port: e000 
  bus-ID: 05:00.0 chip-ID: 8086:24f3 class-ID: 0280 

and on my live install where it was working fine it was

Network:
  Device-1: Intel Ethernet I219-V vendor: Micro-Star MSI driver: e1000e
  v: kernel port: f000 bus-ID: 00:1f.6 chip-ID: 8086:15b8 class-ID: 0200
  Device-2: Intel Wireless 8260 driver: iwlwifi v: kernel port: e000
  bus-ID: 05:00.0 chip-ID: 8086:24f3 class-ID: 0280
  Device-3: Microsoft XBOX ACC type: USB driver: mt76x2u bus-ID: 1-7:5
  chip-ID: 045e:02fe class-ID: 0000 serial: <filter>

Can you give a full inxi -Fazy output for both?

Not sure if you edited your first message but I though you had issue only on WIFI and wanted to check the kernel version difference.

Did you update the system in between the working and non working state of your WIFI?
Did you install a program that may block the whole networking?
Did you configure something somewhere?

I edited it because in the first sentence because I said something like “I used for a few all beforehand” or something like this.

Only thing I tried yesterday was installing virt manager and testing out an arch install

I might go back to an older timeshift backup but for some reason it doesn’t seem to take scheduled backups automatically so my last timeshift backup is 1 month ago

Edit: Ok I just went back to my last snapshot and it didn’t solve the issue

I think I’ll completely reinstall my system because I really need to have internet. Sorry if anyone was having the same problem but I couldn’t personally find an easy way to do it so I couldn’t find a solution. This was my seems like the only easy way out. I’m leaving this thread open if someone has a similar issue or a Mod decides to close this thread

Update: As I found out when reinstalling Manjaro somehow all partitions from Manjaro got merged in to one big one and everything was working fine except Internet. I don’t know how this happened maybe when trying to install virt-manager (I don’t know how I could exactly merge the partitions tho). When I originally installed Manjaro I used auto install so I’m pretty sure it hate multiple partitions but now I just reinstalled it and found out about it during installation.

Honestly I don’t really know if that’s what caused the problem or if it’s just me guessing but maybe some of you guys know if NetworkManager needs it’s own partition or something

Yep weird issue you got there I couldn’t help more when you replied, and when thinking about the possible culprit after your reply.
