If you have a monitor hooked up to the server, the new IP address will be printed directly on the screen above the login prompt once the boot sequence finishes. Reconfiguring Your Settings Safely
After a hardware change, your NIC might be eth1 instead of eth0 . Run:
If you can SSH into your Unraid server but cannot access the WebGUI (perhaps due to a graphical error), you can use the command line. While logged in via SSH, run the following commands:
Whether you are trying to recover from a locked-out WebGUI after a typo, switching routers, or troubleshooting a fresh Unraid installation, understanding how to manage and reset your network settings is crucial.
# Generated empty config forces default DHCP on eth0 USE_DHCP="yes" IPADDR="" NETMASK="" GATEWAY="" unraid reset network settings install
If you have a monitor and keyboard connected to the Unraid machine, you can reset the network settings directly from the console.
Delete the network configuration file by typing: rm network.cfg Reboot the server by typing: reboot
This guide will walk you through every method to reset your network configuration, from simple file deletions to advanced command-line fixes and complete fresh installs.
Users who cannot access the WebGUI and do not have a monitor/keyboard attached (Headless setup). If you have a monitor hooked up to
During the boot sequence, Unraid will notice that network.cfg is missing. It will automatically generate a brand-new file with default settings, which configures the primary network interface ( eth0 ) to request an IP address via DHCP. Method 2: The Command Line Interface (CLI)
If you want, tell me which Unraid version and NIC model (or paste the output of lspci -k | grep -A 3 -i ethernet ) and I’ll provide exact commands and a driver recommendation.
When the WebGUI is unreachable, you cannot simply click a "Reset" button. You must work directly on the server console or modify the USB flash drive from another computer.
(This handles your main IP, gateway, and DNS settings) While logged in via SSH, run the following
This comprehensive guide covers three different methods to reset your Unraid network configuration, depending on whether you have physical access to the server or command-line access. Method 1: The Flash Drive Method (Easiest & Safest)
If the network still does not work after resetting, try the following steps:
Power on the server. Unraid will notice the missing network file and build a brand-new one using default DHCP settings. Method 2: The Local GUI/CLI Method (No Drive Removal)
