| Wrong NIC assigned | Check MAC address in /boot/config/network.cfg; set BONDING="no", BRIDGING="no" |
| Web GUI still inaccessible after reset | Check httpd service: /etc/rc.d/rc.httpd restart |
| IP conflict after static assignment | Use arp-scan to find free IP or temporarily set DHCP |
If nothing works—if your USB drive is corrupted or you deleted the wrong file—you can install a fresh copy of Unraid on a new USB drive, but keep your old config.
Resetting network settings in Unraid is straightforward when the configuration file location and local access method are known. Administrators should follow a backup-first, reboot-last approach to minimize downtime. This procedure restores both DHCP and static IP configurations reliably.
What if you don’t have a monitor attached? What if your server is headless in a closet? You can still fix it using any other computer (Windows, Mac, Linux). unraid reset network settings
Step 1: Remove the Unraid USB Drive Properly power down the server by holding the power button (not ideal, but necessary if you can't SSH). Remove the bootable USB drive.
Step 2: Plug it Into Another Computer Your Unraid USB is formatted as FAT32 (or generally readable by any OS). Plug it in.
Step 3: Navigate to the Config Folder
Open the USB drive. You will see a folder named config. Inside that folder, look for two critical files: | Issue | Solution | |-------|----------| | Wrong
Step 4: Delete or Edit the Files
Step 5: Safely Eject and Reboot Eject the USB drive, plug it back into your Unraid server, and boot. Congratulations—you are back on DHCP.
Unraid stores network settings primarily in /boot/config/network.cfg. Improper changes via the web GUI, plugin conflicts, or hardware changes (e.g., new NIC) can break remote access. When web GUI is inaccessible, administrators must use the local terminal (keyboard + monitor) or IPMI to recover. Step 4: Delete or Edit the Files
Delete or rename the config file and reboot:
rm /boot/config/network.cfg
reboot
After reboot, Unraid generates a new file with DHCP enabled on the first active NIC.
