My ASUS RT-AC86U will not suggest the latest BIOS update

[999cm999]

Hi,

I have an ASUS RT-AC86U wireless router that I bought last year.

I've noticed that my router does not seem to want to update to the latest firmware.

When I login to my router via my Windows 10 machine, and I goto the Administration section and click 'Check Update' it says:

The router is checking the ASUS server for the firmware update
Current Version : 9.0.0.4.386_41994

It checks for a bit, and then says:

The latest version : The router's current firmware is the latest version.

So I just assumed I was on the latest version.

But today I went to the ASUS website to check and see if there were any newer ones.

I found mine:

Version 9.0.0.4.386.41994 Beta Version
2021/02/03 61.7 MBytes
ASUS RT-AC86U Firmware version 9.0.0.4.386.41994 (Beta Version)

But then I noticed that the latest version is listed and it seems to be much newer:

Version 3.0.0.4.386.45956
2021/11/25 62.68 MBytes
ASUS RT-AC86U Firmware version 3.0.0.4.386.45956

So I am now wondering, should I manually try to update my router? Or just let it sit at Version 9.0.0.4.386.41994 like it seems to want to?

Thanks!

Hi,

the version of 25-11-2021 is indeed the newest version. 45956
9.0.0.4 is beta version, 3.0.0.4 is official version. I think best is to upgrade to official version.

Yes, beta versions must be upgraded manually.

Ok thank you, do you think I should contact ASUS about this? It seems odd that my router is selecting to stay on an older beta version rather a newer official version.

Thanks again!

Oh I see now. That's odd because I never updated this router since I bought it. It came with that version 9.0.0.4 installed. I bought it new from Best Buy. Thanks!

Possible, I suppose, given the beta firmware is listed online with released firmware. If so, not nice, Asus! Or maybe you got a returned router... people like to mess things up and then return them... anything is possible.

No. Read the beta firmware description:

“Please be noted this is a quick fix beta version for DNSmasq vulnerabilities. Refer to "Method 2: Update Manually" in https://www.asus.com/support/FAQ/1008000 to update this firmware.”
