@RudhyR Use a Network Analyzer App.  It should show two 6 GHz channels with the same MLO SSID as the 5 GHz if I am correct.  There hasn't been a firmware update since January I've got nothing on you don't worry....

  @IrvSp Here's a screenshot:

The program you pointed me to, at least on iOS doesn't show me that.

Doesn't matter, that is all non--Information when I want to KNOW which BAND or BANDS my iPhone is connected to under the MLO SSID.

Using Acrylic Home I can get similar info like you posted.

Here is what my PC is using when connected via MLO for instance:

See, I can tell it is connected to the 2.4 + 6Ghz bands, that is what I'm trying to see on the iPhone.

Yes, I can tell what SSID I am connected too, but unless it is on this Deco, the 6Ghz SSID and assuming the shared 2.4/5Ghz SSID is not broken apart I can't tell. Using the 3 band MLO the iPhone could be on any one of them. I'm betting it might even switch depending on how far from a Deco it is as 2.4Ghz travels stronger far from the Deco.

  @RudhyR I was trying to research why Network Analyzer doesn't show detailed info for @IrvSp on the iPhone.  It seems that iOS blocks sharing this info with 3rd party apps.  The Jiri Techet programmer explains it as a security issue, and notes that Apple's WiFi app (I unfortunately forgot which one because it seemed to use old WiFi standard,) does have access to this info...

Phones seem to connect to a single band at a time even if it is an MLO enabled SSID.  I would suggest changing 6 GHz-1 bandwidth to the minimum and 6 GHz-2 to 160 MHz.  (I believe the sweet spot for iPhone is 160 MHz).  See if your iPhone moves to 6 GHz-2.  I'm sorry but I read your post twice and didn't quite understand your conclusion.  I think this is because on my Range Extenders I am required to set up individual SSID for 2.4, 5, (and 6 GHz if available), in order to enable MLO, meaning I am required to have a non-MLO SSID for at least two channels, then can create an MLO SSID with those channels that are ON.  If I turn off the regular channels or leave only one on, it says I can only create an MLO SSID if more than one (non-MLO) channel is created.  From this 6 GHz-1 had to be ON for you to also use it for MLO...

Seems iOS, both on my iPhone and iPad does not disclose the band one is on, only the SSID when connected to the Deco.

Now interestingly, the iPad is connected to the SHARED SSID for the 2.4 and 5Ghz band... When I look in the Deco app for its connection is shows 5Ghz. iPhone connected to the MLO SSID, the Connection shows MLO, not the specific band it connected too (I do not think iPadOS supports MLO even)?

Windows 11, no problem, it shows the band connections.

Has nothing to do with the Backhaul methods. I'm using a wireless Backhaul.

If the Deco can not support MESH not much you can do about it.

It might have been on a later F/W update as well for my BE68? I recall after installing it I did get the prompt to enable the 3 bands as part of the Shared SSID? Check to see if later F/W for your Deco was posted here? Doing the test for Update in Deco app doesn't cover all the ones released here.

@jzchen  thank u a lot for the followed up on this! Lol sometimes is hard to explain the things. I did that test to proved that at least for what I can see, the MLO network will use 6ghz-1 all the time plus the 5ghz band, in my case for my deco BE95 MLO only allows me to set those 2 bands.

Regarding Ipad, according to apple the following models are the ones that only support MLO. If yours is one of those then it should, try forgetting your Main network on the Ipad and connect only to your MLO network. Make sure Private Wifi Address and Limit IP tracking are disabled.

Wi-Fi specification details for iPad models

Wi-Fi specifications for the following iPad models are detailed in the table below.

• iPad Pro 13-inch (M5)

• iPad Pro 11-inch (M5)

These models also support Wi-Fi 7 in the 2.4 GHz, 5 GHz and 6 GHz bands, and Multi-Link Operation (MLO).

  @RudhyR 

Yes, I know that, and I have an iPad Air 13" 2025 model.

It DOES connect to MLO SSID...

What I want to know, even if it doesn't 'support' MLO, which BAND did it connect to of the 3?

How can I tell that is the question?

No info on the iPad nor the Deco  app.

  @RudhyR 

Hmm, looks like I found the answer on the iPad Deco App.

Selected the on-line iPad, and it shows connected to main Deco on 5Ghz... it got that, not sure why out of the 3 band MLO... would have expected the 6Ghz to be tried first? I can connect to it though, but why it wasn't I don't know?
