By deleting the network.cfg file, you effectively "factory reset" the communication layer of your server without touching your data, parity, or app configurations.

If you have a monitor and keyboard attached to your Unraid server, this is the fastest way to get back online. Unraid stores its network configuration in a specific file on your boot drive. By removing it, you force the system to regenerate a default configuration using DHCP. Log in to your server locally using the root account.

Here is the comprehensive guide to resetting your Unraid network settings via the command line or flash drive. Method 1: The Quickest Fix (Command Line)

Upon restart, Unraid will look for a DHCP server (your router) and assign itself a new IP address automatically. Method 2: The Flash Drive Method (No Monitor Needed)

If your server is "headless" (no monitor attached), you can reset the settings using any other computer (Windows, Mac, or Linux).

Type the following command to navigate to the network config folder: cd /boot/config Delete the network configuration file: rm network.cfg Reboot your server by typing: reboot

If you have multiple ethernet ports, Unraid might try to "bond" them. If you only have one cable plugged in, disabling bonding in Network Settings often improves stability.

Right-click and delete the file (or move it to your desktop as a backup).

Shut down your Unraid server (short-press the power button or pull the plug if necessary).
