Asus ROG AXE 11000 Mesh stability Issues

[Pcardoso]

Hello,

I have an Asus Mesh Network inside my home. I have four floors and I have four Asus mesh NODs. The main one connected to the ISP modem the one on the ground floor. The other three are connected to the main one by lan for speed and i expected stability. Every 7 to 15 days the network crashes and the NODs start to not communicate with each other and the only solution is to reboot all. What a crap of mesh system. Can you help me?

Is ethernet backhaul mode on?  If yes then hopefully turning it off will help.

[Pcardoso]

Yes it is configured as prefered backhaull mode.

But even if it is not should not the system try to find best backhaull mode between cable or wifii instead crashing.

[jzchen]

Yes, the system reserves bandwidth for backhaul in case an Ethernet cable is disconnected or damaged.  Are you on the most recent firmware?

As I understand Ethernet Backhaul Mode frees up WiFi bandwidth but if the cable is disconnected then the node will immediately drop.  (Sometimes after reconnection they stay disconnected).

With Ethernet connection "preferred" that means Ethernet Backhaul Mode is disabled.  With Ethernet Backhaul Mode it would say "Ethernet Only".

[Pcardoso]

I have now the firmware 23801 (Not the last) because every time I install an update the system stop communicating and i loose about 2 hours recovering it. The update has less then 3 weeks and I will wait 2 or 3 weeks more to install it.

Yes with ethernet you have 6E for wifi and with wifi this is used for backhaul.

Can you please clarify last paragraph?

Since you have multiple floors, the wired backhaul is best.  As you probably know, the signal propagation from a Wi-Fi antenna is perpendicular to the direction the tips are pointing.

You say the system fails every 7 to 15 days.  Are you seeing anything during that time which would cause such an occurrence.  If your system was seeing errors, there may be a time when they become unacceptable, so the system shuts down.  If not that, is there anything else, physically, that might be involved.  Could a neighbor be involved?

Are you running the Ethernet from the mesh nodes straight to the main router, or through the other mesh units?

You could turn off one or more mesh unit for testing.  You should be able to just turn it back on and give it some time to be recognized.

The logs are not easy to interpret, but if you knew exactly when the problem occurred, you might be able to see something.

[Pcardoso]

Yes the propagation is 90 degrees with the antena.

Neighbour I dont know if he knows something about this. If some erros occur could be good if the Router send some info about.

In the past one of the NODs was a asus GT6 10000 a lausy router from Asus. I get rid of it. Now i have four ROG AXE 11000.

Yes the 3 NODs go diretly to the main router and after that goes to ISP modem.

I will try to see the log after a crash.

Hello everyone,

I have cleared the log and now i am analysing in detail the log.

For now i have diacovered problems in my Storage (NTFS errors) and a lot of roamast (Roaming assitance). But no crashes for now.

This is the official instructions on how to set up AiMesh with nodes (and various network connections):

https://www.asus.com/support/faq/1044151/

Please check it and confirm which one your system follows.

It does not mention/advise Ethernet Backhaul Mode, which may or may not help.  I use Ethernet Backhaul but do not have Ethernet Backhaul Mode turned on because the GT-AXE16000 can get disconnected somehow, then lost as a node, requiring a hard reset and re-adding to AiMesh:
