Flint 3 difficulty with 5ghz and 6ghz

Routers
1

I have just setup my Flint 3 router. I’m coming from an Asus RT AX68U Pro. I kept the same SSID and password so that my household could connect without manual setup etc…

So 2.4, 5 and 6 ghz are all the same SSID and password. But all of my devices connect to 2.4 no matter what I do.

I enabled MLO, and used the same SSID and password, but now I have two networks with the same SSID to connect to. However, now my devices can connect to 5 and 6 ghz bands. None of my devices are wifi 7, but several have 6ghz capability.

Any advice here?

Hi

MLO (Multi-Link Operation) is still not widely supported across devices and operating systems.
For example, Microsoft only added support starting from Windows 11 version 24H2, and Apple from the iPhone 16 series.
Therefore, it’s recommended to create a dedicated SSID for MLO.

Since the 2.4GHz band is more susceptible to interference, it’s also advisable to exclude it from the MLO frequency set.

As for combining 2.4GHz, 5GHz, and 6GHz under a single SSID — due to its physical properties, 2.4GHz signals often appear stronger, causing many devices to prefer and remain on that band, even when faster options are available.
To balance performance and ease of use, we recommend creating a separate SSID for 2.4GHz and a combined SSID for 5GHz + 6GHz (keeping the current naming convention).
This setup minimizes manual adjustments for family members while maintaining optimal connectivity.

Thank you. Will give that a try.

I have a Pixel 7. It can see and connects to the MLO SSID. Is that beneficial in any way? Or would it be better to connect to the 6/5 combined SSID mentioned in the above post?

Under ideal conditions, MLO can aggregate the speeds of multiple bands, meaning the speed you get will be the sum of 2.4GHz + 5GHz + 6GHz.

A unified SSID across multiple bands allows switching between 2.4GHz, 5GHz, and 6GHz, with the resulting speed being one of these: either the 2.4GHz speed, the 5GHz speed, or the 6GHz speed.

However, note that in MLO scenarios, if interference occurs on a particular band, MLO will attempt to avoid using that band.
Consequently, it may not always be possible to aggregate the upstream band rates.

Additionally, during handover processes, this may lead to increased latency and minor packet loss.

This is why we recommend not including the 2.4GHz band in MLO's frequency combinations.
