Actually folks I upgraded to this FW Version 3.0.0.4.386.43129 last night on an AiMesh rt-ac5300 main node + (using also 3 rt-ac68u nodes) and it broke the connection to my cable modem. Essentially admin page showed X for internet connectivity. I hard rebooted the primary and all the nodes but that did not fix things. I even bounced the modem and then bounced all nodes sequentially starting with rt-ac5300, but still no connection. I flashed back to Version 3.0.0.4.384.82072 and magically things came back to normal.

Note1: I did this upgrade via the admin gui upgrade button in the FW upgrade section/page.I will attempt the same from a downloaded trx and checked with md5sum code.

Moving from the 384 release to 386 requires a factory reset , a dirty flash will cause issues.

I'm confused right now, this specific post and update is for the AC88U.

I tried to install the firmwareverison 3.0.0.4.386_43129 via the GUI of the RT-AC68U.
The result is, as before, the old version 3.0.0.4.386_41634 is shown as installed after the update attempt.
Even after all conceivable reboots no change.

sorry my fault

Well the 5300 is a glorified 88U , but hopefully poster downloaded the firmware for the 5300 as the MD5 checksums are differrent.

I am currently running the beta version Version 9.0.0.4.386.41994 downloaded from the Asus site. My router reports that as the latest version so I cannot update it via the router GUI.

I assume I must run the update manually. Will this be easy or is there any trick I need to know?

Once updated, do I need to do a factory reset?

 

[susa-me]

I personally wouldn’t run a beta fw. I think it’s untested on every model and think that asus is having its users do the testing for them.
If you can’t go without internet, I suggest you don’t run beta fw on your “production” router. My 2 cents.

I got the same issue with RT-AC1900U. Just update manually - download new firmware - choose update - point firmware file and start again.
Worked like a charm.

I wasn't able to get this (43129) working on my RT-AC88U, factory defaults reset didn't help, when rolled back to 41700 no issues.

 

[azbruno]

I ran a manual update from the just prior beta (9.0.0.4.386.41994) through the GUI and it worked perfectly. No issues.

 

[st939]

Change your signature, lucky you.

You misunderstand this line entirely,

This refers to the addition of AIMesh > System Settings > System Reset to Factory Default as a GUI item for the AIMesh 2.0 system

It does not imply, force or otherwise require a factory reset, and the 386 firmware runs with a persistent 384/385 configuration just fine.

The implementation of the auto update system requires that dirty updates be as smooth and problem-free as possible, if you're one of the few who significantly alter NVRAM CVARS, then all bet are off, but the necessity to start from scratch is not there.
