XT9 channel width?

[Valdo]

Hello,

wondering why my 3 unit XT9 mesh system works on channel 40 with 160 MHz channel with and other node on channel 100 with 80 MHz channel with. Shouldn't be both 160MHz as this is set for both 5GHz bands in settings?

(Backhaul is ethernet exclusive)

Thank you

Hi @Valdo ,

Thank you for your question. 

Regarding the wireless network channel issue you encountered, we would like to understand the situation further.

To achieve the best wireless connection quality, the router will automatically adjust the channel and bandwidth based on the wireless environment. 

When you enable DFS channels and set the bandwidth to 160MHz, if the system detects radar signals in the surrounding area, the router may automatically switch to an 80MHz bandwidth to avoid signal instability.

We suggest you:

1. Check firmware version: Please ensure that the firmware versions of your router and all connected devices are the latest for optimal compatibility.
2. Check channel settings: Double-check the channel and bandwidth settings for the 5GHz band of your router. You can find the relevant settings in the router's management interface.

You can refer to the following FAQ for more information about DFS channels and bandwidth adjustments:

Hi @Aureliannn_ASUS
Thanks for your reply, I unchecked the "Automatic channel selection including DFS channels box", but after apply and reboot it was thick again and nothing changed - In the 5GHz bands there are 3 BSSIDs on channel 36/160MHz and another 3 on 104/80MHz. But I'll leave it at that, it was just a question out of curiosity.
My main problem, which no one from Asus has answered (4 requests for help via the GUI) and no one from this forum either, is that I can see hidden networks, 2 in the 5GHz band and 1 in the 2.4GHz band. All 3 BSSIDs of the hidden networks are logged in the XT9 router log.  Guest network and WPS are disabled, backhaul is ethernet exclusive.

Again, I am asking for help as the WiFi pollution in my area is huge and by turning off the silent hidden networks it will reduce the interference and I assume it will also reduce the power consumption of the XT9 mesh.
Maybe you can give me an explanation or some steps to fix this problem. Thank you very much.

So, I found out that the above mentioned hidden streams are the backhaul of Nodes. Apparently Asus has a bug or simply don't care about this. 

If the backhaul of XT9 is set to Ethernet primary and happens that the backhaul wire is pulled from the router or Node is switching automatically to wireless backhaul. Perfect!

In case that the backhaul is set to Ethernet exclusively, the wireless backhaul should be OFF!

So Asus, be so kind and adjust the firmware accordingly as firing unnecessarily 3 streams which pollute the environment and increase the power consumption of involved devices is not nice. Please proceed!
