Title: Lost GUI and "Media disconnected" on OPNsense after backup restore
Post by: AlexOd on July 14, 2026, 02:16:22 PM
�Hi everyone,
�I am seeking help to recover my OPNsense installation. My network was stable until I restored a configuration backup, and now I am completely lost.
I spend whole day trying to figured out.

�My network was configured with OPNsense as the primary router and my ASUS RT-AX88U Pro acting as an Access Point (AP).

While my PC (connected via Ethernet to the OPNsense LAN port) had a stable, working internet connection, the ASUS AP was failing to provide internet access to wireless devices.
�I previously had to reinstall OPNsense entirely because an AI-guided configuration resulted in incorrect settings and system instability.
�I attempted to restore a configuration backup I had saved a few days ago to resolve the ASUS AP connectivity issue.

The Issue:
�Immediately after the restore, I lost all internet connectivity, and I can no longer access the OPNsense Web GUI.
�My PC now reports "Media disconnected" on the LAN interface, even though the hardware and cables were working perfectly moments before the backup restore.
�My OPNsense console confirms my interface assignments are WAN as igc0 and LAN as igc1, but despite these assignments, the system is failing to pass traffic.
�I currently only have access via the local OPNsense console.

My Questions:
�Since the restored backup appears to have broken the interface configuration or firewall rules, what is the best way to clear the bad configuration settings via the console to regain Web GUI access?
�Should I use Option 4 (Reset to factory defaults) in the console? Will this definitively resolve the "Media disconnected" state and restore GUI access?
�What is the best way to safely import only specific sections of a backup in the future to avoid these types of conflicts?

Alex

Also forgotten mentioned. I restored a v25 backup onto a fresh OPNsense v26 install, and now my interfaces report "Media disconnected" and the Web GUI is unreachable.
I forgot that it had 25 version.

Did any interfaces change between the backup and when you restored it? Did you reboot after the restore?

Actually I was able to reset to default settings. So I have restored enternet.
Thank you.

Now I have to find why my Asus router dont get enternet from port 3, whereas PC getting enternet thru port 2.

Thank you for reply.

Is the Asus AP on port 3 on it's own network or on the same LAN the PC? If on the same LAN as the PC, did you createa bridge in OPNsense?
