Unraid Reset Network Settings < 1080p — 4K >
Unraid’s config is stored on the boot USB drive (/config folder).
You can plug the USB into another computer and:
dhcpcd.conf if present (very old versions).When the web UI is dead, the physical console is your best friend.
Step 1: Get Local Access
Plug a monitor and keyboard directly into your Unraid server. Log in as root (enter your password if you set one).
Step 2: Blow Away the Old Config Unraid stores network settings in a few simple files on your boot USB. Delete them: unraid reset network settings
rm /boot/config/network.cfg
rm /boot/config/network.cfg.bak
rm /boot/config/network-rules.cfg
Step 3: Reboot
reboot
When the server comes back up, it will act like a fresh install: DHCP enabled on the first active NIC. Check your router’s DHCP table for the new IP, then access the web UI.
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’s config is stored on the boot USB
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: (Optional) Delete dhcpcd
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.
