Has anyone already upgraded to this firmware version 3.0.0.4.388_25136? I have to provide a stable network and can't afford tinkering with firmware releases for hours.

I have a set of two ET9s on FW 3.0.0.4.388_24829. One runs in operating mode Wireless Router, the other as node. They are connected through ethernet backhaul in order to have all frequencies for clients and as 6GHz is no good for backhaul if stations are separated through walls.

In order to use the full set of features the AiMesh operate in a double NAT set up behind my ISP's router.

Wifi6 (2.4GHz and 5GHz plus 160MHz) is fast and reliable when used from an office Lenovo PC or my Pixel 6 cell phone. I can utilize the full bandwidth that my ISP provides. So I am happy camper here.

Also the additional features, safe surfing, etc. are all great. The fact that I am not forced into a subscription model was one of THE factors making me buy Asus ET9s.

So far so good, now for the problems:

Wifi6E is supposedly broadcasted all the time (according to web UI and app), yet it is received only occasionally through my new Asus ZenBook and very briefly only through my Pixel 6 phone - right after resetting the network connections.

I have to add my Asus ZenBook started to receive 6E only after I upgraded the driver for my Intel(R) Wi-Fi 6E AX211 160MHz adapter to the latest WIFI7 driver 23.80.1.3

Currently I receive on 6 GHz on channel 197.

Any ideas, why 6E disappears sometimes?

FWIW, I would assume either the router 6.0 radio stops broadcasting, or broadcasts a signal that the client does not support/is unable to 'see'. And troubleshoot from there. Installing latest firmware from scratch would be a likely first step... new firmware is what this thread is about.

I have not. I'm too worried any new updates will mess it up, why touch something when its finally working as its supposed too, right.
If on the other hand I was having issues then I would upgrade. maybe it fixes it maybe it doesn't, with Asus is hard to tell and Support doesn't really understand how wifi tech works. your better off googling the issue.

After running for 24 hours this version seems more stable than the newer November 2024 version. Cmon Asus, focus on making 3 node aimesh stability the #1 priority. Stop autonomously making the mesh nodes roam to try and find a better path when my aimesh settings are not in Auto mode. I want my 6ghz backhaul and exact mesh backhaul to connect to.

I had issues as well initially on the 6ghz backhaul using 2 nodes but after about 50 reboots and throwing it against the wall it ended up working on its own. Might want to check if you have radar equipment near by like police station or weather radars, i've read this can affect 6ghz depending on how close you are. I have 2 nodes working from corner of my basement to 3rd floor of my house. Even when signal turns "yellow" it still maintains the 6ghz and has been working for about 6 months now at full speed of my ISP.
yes Asus has problems but their radio waves seem far superior than other brands I've tried.

try tinkering with wifi mgt screen. i have mine set to use 6ghz as priority, and prefered uplink AP set to Auto.

Network settings:
Smart connect - off
802.11ax mode - off
I have 2.4, 5 and 6 Ghz all enabled
I notice the 6ghz has WPA3-Personal encryption while 5Ghz is using WPA2.

Wireless try this:
2.4Ghz-20/40 Mhz
Channel-Auto mine shows 3

5 Ghz-20/40/80 Mhz, Enable 160 off
Control Channel-153
Auto select channel using DFS-on

6ghz-160
Control channel-165
Enable PCS-on
Protected Mgt Frames-required

Key to all this is the control channels. If your neighbours are using the same channels this will affect your wifi as well. Try using a free wifi scanner that scans the air waves and channels, or hack your neighbours wifi and change their channels away from yours.
hope this helps.
and yes im not using their latest firmware. "if it ain't broken dont upgrade"
