Hello everybody!

 

I have some questions about WiFi 7 and MLO.

 

Client Device: Samsung S24 Ultra

 

Upgraded to beta firmware due to OFMA + MU-MIMO bugfix:

https://community.tp-link.com/us/home/forum/topic/662496?replyId=1346590

 

 

How should WiFi 7 MLO work? If you enable 5 GHz and 6 GHz, should both bands be used?
Like of like 4G LTE or 5G NR Carrier Aggregation Bands?

Connection to the 6 GHz or MLO SSID makes no difference here.

 

MLO really seems not to work at all. Is there a way to test this?

 

I always get:

9bb79782e4eb4e94af4a924f34a40df5

 

Please Note:
Samsung S24 Ultra seems to have some issues providing the proper WiFi 7 info as well.

Service Menu: Call > *#0011# > right corner top select three dots then select WiFi

The above screenshot is of this service menu.

 

 

Another thing i also keep reading:
Does WiFi 7 use 160 MHz or 320 MHz bandwidth?

Again via the service menu you can check this:

If the Link Speed is 5764 Mbps then the device uses 320 MHz.

If the Link Speed is 2882 Mbps then the device uses 160 MHz.

Or better said: A Link speed of more than 2882 Mbps = 320 MHz. 320 MHz bandwidth can only be done in the 6 GHz band.

It would be awesome to be able to combine 5 GHz + 6 GHz bandwidth together. As i think MLO should do. Or it isn't explained properly.

https://www.tp-link.com/us/blog/1067/what-is-wifi-7-s-multi-link-operation-mlo-/

 

I have tested this in the spectrum:

32f31b9c32b14212bdeb2d105c9ddb21
 

 

So how do we get to use 5 GHz + 6 GHz together? Or am i misunderstanding what MLO should do?

 

I am trying to push my Router and Phone to the limit when it comes to WiFi 7.

This is the  fastest i have done so far:

a4c437cdeeb54c569044a5e1f80f74c9

 

 

Bonus bug:
The TP-Link Be800 and/or Samsung S24 Ultra show a WiFi 7 icon when the 5 GHz SSID is in the Available network list.

But once you connect to the 5 GHz SSID you will see a WiFi 6 icon appear in the top right corner of the Samsung S24 Ultra.

Also NETWORK: 802/11ax is used then. Max Link Speed 2401 Mbps.

Thanks! And good luck with this new tech!

I installed this firmware. Do you know if WiFi 7 MLO should connect to 5 GHz and 6 GHz at the same time?

Please inform me. So i know what to look for. And if required, contact Samsung with my findings.

 

Thanks!

Hello? Anyone there?

 

Can some one please answer my how does MLO work question?

So, if MLO is not working, i can ask Samsung. Or are we being fooled?

 

A not so difficult question i would say?

 

Thanks again!

Samsung S24 Ultra 1 may 2024 updates still does not connect more than one WiFi 7 band.

Meaning, MLO does not work.

 

TP-Link is wrong?
Samsung is wrong?

Anyone from TP-Link can answer my question please?

 

I need to know in order to advance my research in WiFi 7 MLO.

 

Thanks!

Installed 2024-05-23.

 

Still no MLO connection. Only 5GHz or 6 GHz.

 

How should MLO work?

https://www.tp-link.com/us/support/download/archer-be800/v1/#Firmware

 

Archer BE800(US)_V1_1.1.4 Build 240520

 

Note:

Optimized wireless performance;

Enhanced system stability.

 

Still no 5 GHz + 6 GHz MLO connection possible.

 

 

 

Note 1:
The newly released acer DOT com/acerwave7 says it can only do 2.4 + 5.0 OR 2.4 + 60 GHz MLO.

I am guessing the TP-Link uses the same or similar chips. So we and/or TP-Link have been fooled by marketing.

 

news.acer DOT com/acer-unveils-wave-7-mesh-router-with-wi-fi-7-and-multi-link-operation-for-seamless-home-connectivity

Band Support: 2.4 and 5 GHz/ 2.4 and 6 GHz

 

Note 2:
I got some notices people have replied, but i cannot read any of them?

  @5Guru 

Did you enable the MLO network in the setting? 

e3b148feffbe47fc815e682a90e9be47

Then you get to choose which bands to include in the MLO network. In my case, BE550/BE9300, it supports MLO in 5GHz and 6GHz bands. 

 

You also need a Wifi 7 compatible devices to use it, too. I see you have S24Ultra. I have one, too, but I live in a country where wifi 7 hasn't been approved yet. My S24Ultra firmware is locked at Wifi6E so right now I disabled the MLO network.

 

Hope it helps.

Yes: tp-link-be800-wireless-settings_2024-02.jpg
 

42ffe44c63e0459c82736029f2ac82c6

It seems only:
2.4 + 5 GHz
OR
2.4 + 6 GHz
can be used as MLO

 

You can indeed select 5 + 6 GHz in the settings.

But the Samsung S24 Ultra usually only connects to 6 GHz then.

Sometimes also 5 GHz. But never are 5 + 6 GHz both shown as Associated. Only one at the time, as the first screenshot shows.

 

 

When selecting 2.4 + 5 + 6 GHz, then:
Link 0: Associated 2.4 GHz
Link 1: Unassociated 5 GHz
Link 2: Associated 6 GHz

But this is very unstable and keeps losing connection almost directly.

Didn't test this for a long time, but this is with the latest firmware.

  @5Guru The connection also depends on the receiving devices, too. In this case it's the S24Ultra. Having 3 bands in MLO doesn't necessarily mean it will connect to all of the bands at all time. To over simplified things, an antenna can send/receive a radio signal of a specific frequency for a period of time, meaning one antenna could work with single frequency, or switch between frequencies supported by the connected circuit if designed to. Now that BE800 has many antennas. Each of them could be programmed to operate in a specific frequency simultaneously. For example, 2 for 6GHz, 2 for 5GHz, and 1 for 2.4GHz given MLO is enabled. No one except TP-Link folks know about this algorithm.

 

Now come back to S24Ultra phone, I'm too lazy to research how many antennas the S24U has, but let's say it's got 2 antennas. The phone software could also programmed to operate at most 2 frequencies in multi-link operation, at any given time, too. See where I'm going now?

 

I heard the BE800 firmware is very problematic. My smaller BE550 as well unfortunately. They seem to have similar (same actually) bugs. I'm guessing both model firmwares are from the same based firmware TP-link used internally. So it could be the BE800's faulty firmware, or the S24U's radio module designs, etc. You may need to confirm with TP-link support or engineers regarding the above info.

 

The only way to know is to find another Wifi 7 MLO enabled routers to try on with the same app you were using. I wish you good luck in the research. If it's not too much would you come back and update about the findings? I'm a little disappointed in BE550, so maybe I would switch to something else in the future.

  @5Guru Some info graphic about MLO and it's various operation modes.
