TP-Link Tri-Band BE9700 - Archer BE600 - MLO Issue with Windows 11
Big issues with TPLINK not even listing their own product which I bought on Amazon. The actual Model number is BE600 on the back of the unit. You can search for BE9700 or BE600 on Amazon to see exactly what I bought.
OK, now that is settled...
My issue is, I have a TPLink Archer TBE550E Wireless adapter for my desktop. It is WiFi7. The best I see that TPLINK offers. I have the router as explained above. When I setup MLO in my Wireless settings on my router the WiFi7 adapter will only connect to the 6Ghz and 2.4Ghz frequencies. Together my aggregated link speed is 6453/6453 Mbps. That's great!
However, Wifi7 MLO claims it can connect 6Ghz+5Ghz+2.4Ghz frequencies all together. I have never seen this. Anyone know why?
I am running Windows 11 with the latest updates as of today. Sept. 22, 2025.
Second issue:
I peformed an internal wifi transfer from one desktop to the other. Both on the same version of windows & both using the same equipment (wifi adapter and on the same router). Maximum upload was 1.5Gigabit. Now, that is fast, but where is the supposed max aggregated? Am I being slowed down by nvme speeds? 1.5Gbit? I think not.
Thank you,
Ryoga

@Ryoga if 6ghz at 320mhz channel width is in range and used, the adapter will use this only instead of trying to work across multiple frequencies since this already gives the maximum link-rate that the adapter support (5.8 Gbps). This also has much less possibility of interference since there are not as many devices transmitting on the 6ghz band as 2.4 or 5ghz.
Wifi 7 is still young and new, only certain adapters / routers are designed to use all 3 frequencies at once if they are in range.
as for your 1.5gbit internal speed test, what program / file were you using for transferring between the two computers and what was the wifi link rate at the time of transfer on each of the computers?
If you are transferring a single file stored on an NVMe drive (that has a sequential max read/write speed of at least 3GBps), then depending on the program and protocol used for transfer (if it uses multiple threads on your CPU unlike traditional SMB through file explorer) it should be higher than 1.5Gbps. CPU power settings in Windows and the model of CPU can affect this of course as well.

@Ryoga This is normal operation. The MediaTek MT7927 chip installed in the TBE550E is a DBDC (Dual Band Dual Concurrent) chip that supports 2.4G+5G or 2.4G+6G STR mode. Therefore, 2.4G (40MHz) + 6G (320MHz) = 688Mbps + 5764Mbps = 6452Mbps, which is displayed as approximately 6.5Gbps.
The 2.4G + 5G + 6G MLO you mentioned is called TBTC (Tri band Tri concurrent), and as far as I know, there is no client that supports this on Windows, and the only one that supports this is the MT6653 on the MediaTek Dimensity 9400.

@Ryoga I have the same adapter, it will connect on 2 channels, My iPhone can connect on 3. They are still updating the drivers for these so maybe it will connect on more channels in the future.

@Ryoga It's pretty much based on signal strength, I have another system with an Intel wifi7 chips. It sits right above the router and uses 5,6. The one with the tp-link adapter is farther away and has more walls in between.

@ABC_ChoCo Thank you very much. For future reference I will look up the chip set of the equipment I have to see the capabilities. Stay awesome!

----------------------
The file was 1 large multiple gigabyte file.
The link rate was the exact same, 6452Gbit aggregate.
I was using Windows 11 explorer to connect to the network share and dragged the file in to the network folder (both ways, from one computer to another and visa versa). Therefore it was using SMB protocol.
Both CPU settings are set to maximum power usage, so it is different than default installed settings of the OS.
Your questions hit very good points in which I failed to mention. But, like you said the seq max read/write should be faster. 2 nvme drives both Intel, internal to 1 computer can transfer the same file at 600+Megabytes per second. I was only seeing through the network ~187MBs.
@ Everyone:
I don't mean to sound like upset about this or unappreciative, I am just curious how I can maximize my setup. I thank you all for your responses.
