    Hi Folks, New here..

    I un-packaged my new to me RT-AC66U_B1 router last night and did a reset to factory. Logged in to make sure all was OK.
    Then up graded the factory firmware to Merlin 380.68_2.

    All looks great but near the top right of the main page, there is an exclamation mark blinking. Warning me to upgrade firmware. I am thinking this is standard ASUS firmware.

    My question is, now that this router is running Merlin, do I just ignore the upgrade warning?

    Your router is a ac68u as you know. The latest firmware for it is 384.3 stable. That may be what is going on. If you click on the icon that blinks it may shed some light on things.

    Hi, sorry i did edit my post. Router is a AC66U.

    I will check when I get home and see if it gives me any indication of what firmware it wants to install.

    I just wasn't sure it it wants to pull firmware from ASUS or a Merlin firmware.

    If your router is a ac66u_B1 then it's a arm7 processor. This is the aquivalent to an ac68u. If this is true the firmware you want is the ac68u version.

    As skeal said, the RT-AC66U_B1 uses the same firmware as the RT-AC68U. It does not use the same firmware as the RT-AC66U. It's confusing, but blame ASUS for their weird naming convention.

    You're seeing the blinking exclamation point because the latest stable Merlin firmware for RT-AC68U/RT-AC66U_B1 is 384.3.

    Hi,
    This much I know from the readme-merlin.txt, and have installed
    Devices supported on the legacy branch (380.xx):
    * RT-N66U
    * RT-AC66U
    * RT-AC66U_B1 (use the RT-AC68U firmware)

    I just want to confirm if the alert is for a new Merlin firmware or standard ASUS firmware. Last thing I want to do is revert back to an ASUS Firmware.

    Thank you, that's what I wanted to confirm. As I have read that the ASUS router once connected to the net would want to do a firmware update.

    Just to note, there is an Asus Version 3.0.0.4.384.20308 available for that router:

    https://www.asus.com/ca-en/Networking/RT-AC66U-B1/HelpDesk_Download/

    That might be why you're seeing the update available symbol flash.

    But, just to be clear, you can load the RT-AC68U firmware on this router without issue? Doesn't apply to me, but someone that I was chatting with recently will be in this same position, with a new 66U-B1.

    Once merlin is installed it will only signal merlin updates.

    Didn’t know that. Thanks for confirming, skeal.
