AI Mesh: channel bandwidth in the repeater

[frabar55]

Hello everibody,

In my system which has an RT-AX88U pro as router and three RP-AX58s as repeaters (obviously in AI Mesh), I changed the 5Ghz channel width to 80 Mhz but this is not reflected on the repeaters which remain at 160 Mhz (this was the one before the change), how can this happen? Thanks for your support

Have you tried rebooting the RPs?

[frabar55]

oh yes many times.

Wireless, Ethernet, or mixed backhaul?

[frabar55]

all the repeaters are connected via Ethernet.

[frabar55]

the strange thing is that it correctly updated the channel width for the 2.4 band

I have a RP-AX58.  It works (a little) better than my RP-AX56, which I hope to replace next.  Which firmwares are they on please, and country located in?

When you look at your connections, are you looking at the Mesh units or the devices connected to the Mesh units.

Since you have wired backhaul, the devices may connect to the entire band on the Mesh units, but if you were using Wireless backhaul, on the 5 GHz frequence, they may not.

the three repeaters have the following firmware version 3.0.0.4.388_24654-g6a82eb6io (I am in Italy);
I am looking at the Netspot monitor which reports the repeaters to be on the 5G band with a width of 160Mhz

What Netscope may be showing is 80 MHz assigned to SSID, and another 80 MHz assigned to SSID_dwb.  SSID_dwb would be a hidden dedicated backhaul channel.  For example you somehow unplug an Ethernet cable between router and node, then WiFi backhaul immediately takes provides connection.

What I suggest trying is enabling Ethernet Backhaul Mode, (if not already enabled):

Under General -> AiMesh -> System Settings -> Ethernet Backhaul Mode (toggle ON).

If it's already on I'm not sure, will have to let it process in my mind...
