The network settings are stored in a single file on your USB boot drive: /boot/config/network.cfg Step-by-Step Reset Procedure Method 1: Using a different computer (Recommended) your Unraid server. Remove the USB flash drive. Plug the USB into a PC or Mac. Navigate to the config folder on the drive. Delete (or rename to .bak ) the file named network.cfg . Eject the drive and plug it back into the server. Boot the server; it will now request a new IP via DHCP . Method 2: Via Terminal (If you have local access) If you have a monitor and keyboard attached to the server: Log in at the command prompt (usually root ). Type: rm /boot/config/network.cfg Type: reboot Important Considerations
