Ubuntu 20.04 - Realtek Ethernet failed after restarting the system
You're just starting with Ubuntu 20.04 LTS. You had an Ethernet connection set up using a Realtek chip, but it disappeared after rebooting. You've tried checking old forum posts and changed a config file, but the issue remains. You attempted to fix it by restarting NetworkManager manually and via systemctl, yet it still doesn't work. Could you find any alternative solutions or tips? Thanks for your help! :c
Running command: ifconfig

It seems there may have been an issue with the NM settings or the NIC isn't being loaded properly. Checking "lspci | grep Realtek" could reveal information about your network card. If nothing appears, running "lspci" alone might help identify the device. A non-root user should still be able to locate it.

Oh no :C It’s just my second day with Ubuntu... I installed Overleaf and VS Code/Anaconda yesterday as prep for CUDA/HELIOS. Since I had the connection ready, I haven’t done anything yet LOL.
The command "nmcli con" initiates a connection to the network interface.
I can't directly access or retrieve files from your system. However, you can open the file yourself by running the command:
```bash
sudo nano /etc/NetworkManager/NetworkManager.conf
```
Once inside, copy and paste the full content here, and I’ll be happy to help you with it!
It looks like you're asking about the NIC status and whether "iplink" displays it. Let me know if you'd like further clarification!
