Asus Firmware Update

[Robert57]

I received the following message in my email:
"WARNING

Backup failed during the F/W Update process to version 3006.102.6.0 on the RT-BE88U router.
Flashing the F/W Update on the RT-BE88U router is now canceled.

Please check backupmon.sh configuration and retry F/W Update from current version:
3006.102.5.0

Sent by the “MerlinAU” utility.
From the “Asus-Merlin” router."

I cannot find a setting in AMTM to 1. suppress the notification of an Asus firmware update and 2. stop receiving such email notifications.

Can anyone help me resolve this issue?

Did you check MerlinAU options? You have installed this add-on...

Have you tried a manual update?
What are your MerlinAU settings (redact server info)?

 

[Robert57]

A new F/W update is displayed in the Merlin Dashboard. However, I have activated Auro Update Merlin AU.I assume that version 3006.102.6.0 is the new firmware for Asus and has nothing to do with Merlin.Am I wrong in this assumption?

3006.102.6.0 is the latest Merlin firmware, released 16 days ago. This would indicate you still have default settings in MerlinAU(?).

Release - Asuswrt-Merlin 3006.102.6 is now available

Asuswrt-Merlin 3006.102.6 is now available. This release focuses on new GPL merge, a complete redesign of the Traffic Monitor pages, and the addition of two new models: RT-BE58_Go - https://www.asus.com/networking-iot-servers/wifi-7/all-series/rt-be58-go/ GT-BE19000AI -...

So, can I install this firmware now and keep all the apps I installed under AMTM?

Am I wrong in this assumption?

Yes you are wrong with that assumption. As others have said, 3006.102.6.0 is the latest Merlin firmware (ASUS does not use this numbering/version format)
You need to review your MerlinAU settings, and specifically your backupmon settings. (As the warning is telling you...)

Please share your MerlinAU and Backupmon settings for assistance.

all the apps I installed under AMTM

Before you install any add-ons please read what they do and how.

 

[Robert57]

Yes, I've become more aware of that now (because of reading).....
This is the error message that appeared:
Dec 11 2025 00:00:55 RT-BE88U-30E0 BACKUPMON[30762] - **ERROR**: Unable to mount to external network drive. Please check your configuration!

 

[Tech9]

Reset your router to factory defaults and start over clean. Don't touch SSH and AMTM before you need something you don't find in Asuswrt-Merlin available options. All add-ons are optional and when needed.

 

[Robert57]

Is that really the only way to fix this error??? That can't be it....

 

[Tech9]

When we have no idea how many "apps" you have installed, for what reason and with what settings - Yes. I asked you what firmware is your router running in previous thread. You never bothered to reply...

 

[Robert57]

It would be very helpful, of course, if you could advertise Asus Merlin and warn people not to use any AMTM functions....

 

[Robert57]

Great support!!! Thank you

This is what I installed under AMTM

**ERROR**: Unable to mount to external network drive. Please check your configuration!

Do what the message says - Please check your configuration!

 

[ExtremeFiretop]

Do what the message says - Please check your configuration!

Or alternatively, disable Backupmon backups from MerlinAU.

Why should the developer of Asus-Merlin firmware need to warn people about using AMTM functions? The router will operate normally without using any of the AMTM provided addon scripts. No one is forcing the end user to run AMTM or install the scripts listed under AMTM. Is it not the end user's responsibility to investigate, and understand, what each of the AMTM listed scripts do BEFORE installing them?

Generally when updating Asus-Merlin firmware any addon scripts should operate as they did previously unless there is a change in the firmware (like moving from 3004.388.x to 3006.102.x firmware) that breaks addon scripts. Quite often the developer of Asus-Merlin will inform addon script developers of changes in the firmware that may impact addon scripts. Sometimes those addon scripts will break with updating the Asus-Merlin firmware. When that happens, see the specific Addon subforum thread discussion for the specific Addon for help and for suggestions on how to fix. Sometimes a simple reinstall of the addon will correct the issue, other times the addon script developer will need to fix the addon script.

PS: In your case your intial post held the answer.

Please check backupmon.sh configuration and retry F/W Update from current version:
3006.102.5.0

So, check your Backupmon addon script configuration to see if there are any issues. Then try updating the firmware to the current Asus-Merlin version (3006.102.6).

And to add, one can reach the BACKUPMON configuration by issuing backupmon.sh -setup via SSH on the router. More on configuring BACKUPMON here:
