Hi, thanks for posting question here.

Can you share the screenshots to show the wireless settings of your MLO network?

And you mentioned " it shows that it is in 802.11ax and the multi Link info is Unassociated with all the Links 0 2 1", is it possible to share the related screenshots or describe more exactly?

Then we will try to confirm for you. Or it is suggested to contact local suppport for direct help.

Hi, thanks for your update.

For the MLO network, did you enable 5GHz&6GHz at the same time?

If you only enable 6GHz band, how about the result？

According to your screenshot, it seems your phone is connected to 5GHz band instead of 6GHz band?

Does the problem only happen on your Samsung S24 Ultra? How about your other clients that support WiFi7?

You may try the pre-released firmware in the thread then confirm again.

Best regards.

Would you please have a try?

1. Can your Samsung phone connect to other WiFi7 network?

2. Can your Samsung phone connect to different  wirless bands of main network properly?

3. If your computer which supports WiFi7 spec can to connect to MLO network properly, it is also suggested to contact the Samsung support for some advice.

Thank you and best regards.
