The only reason to get a wifi 7 router is that it supports wifi 6 better than a wifi 6 router

It sounds like you're talking about throughput aggregation, which indeed no device currently supports. Not even Apple's most recent devices have any sign of it, except that M5 Pro/Max MacBook Pro models are tested for simultaneous transmission on 2.4+5GHz and 2.4+6GHz: https://mrncciew.com/2026/03/17/macbook-pro-m5-wi-fi-7-missi...

> which indeed no device currently supports

Aren't devices with Intel Wi-Fi 7 BE200/BE202 are supporting that?

As well as latest Samsung phones?

AFAIR: the BE200/B202 only have one radio. So no parallel streams on two frequencies.

But they are the best cards around if you want to play with Wifi-7 on Linux. But always go for the latest wireless-next kernel + firmware blobs. Also they are not compatible with AMD mainboards (go for Qualcomm then).

Being connected to multiple frequencies simultaneously is one thing. Actually using multiple of the links in parallel to increase speeds has not really been seen in practice yet. That is called STR (Simultaneous Transmit/Receive; what I called "throughput aggregation" above), which requires MLMR (Multi-Link Multi-Radio), which almost nothing that supports MLO has right now. Maybe some bleeding-edge mesh networks are doing it, and Ubiquiti has one or two products that does it, but you basically won't see it anywhere else and especially not in client devices yet. Intel BE200/BE202 does not actually perform throughput aggregation, it connects to multiple frequencies and then uses only the best of them (eMLSR, or "Enhanced Multi-Link Single Radio").

UniFi UDB-Switch has throughput aggregation for 5GHz + 6GHz.

5GHz? Surely you mean 5000000kHz ;P

That's not controlled, seamless hand-over as we know it from GSM/3G/LTE/5G for 30 years now.

We basically miss all data (received stations/signal levels from both sides, Bit Rate errors, etc.) for making roaming decisions and then to softly connect them to an AP you want them to be on.

Enterprise WiFi is currently mostly "This is a list of APs you maybe can connect to.. have fun.. if you can connect we pre-seeded the AP with some crypto data, so it doesn't take ages to negotiate. Here's your (more or less friendly) disassoc. Fuck off bye."

It does somehow work for stationary setups - but as soon as you have mobile traffic (like walking around or machines moving) with multiple APs the quality hits the shitter brutally.

Currently this gap is being filled by industrial 5G with dedicated frequencies. It's crazy expensive.

So SCTP (multi homing)?

On paper, yes. In the real world, that random Android client is clinging to an AP that can barely hear it while a better one would be available.
