BT Mini Whole Home system with 2 disks with router WiFi switched off. Covers the house well enough and as long as it's at least as fast as my VDSL connection (circa 40mbps) I'm quite content as I don't have any need to transfer data between devices at high speed.
The price was right too as I got it from Freecycle so it was £0.

Do any of them have the new(ish) 5GHz ethernet i/f then?

2.5GBase-T here and in most cases. Cat 5e is definitely okay for that while 5GBase-T it can get sketchy due to the move from 100 MHz to 250 MHz spectrum.

This is why for many years I’ve only ever bought CAT6 or higher.

One reason I havent bothered with anything other than a cheap AP, is I dont have any client devices that have higher spec.  Other than maybe my newest phone which in itself doesnt need 1000s of mbits/sec performance.

Indeed, I found I can use a Gigabit rated PoE splitter for my router at 2.5Gbit, but it absolutely wont work at 5Gbit presumably for that reason.

I have one device connected at 5Gbit using a USB 3.0 adapter (so bottlenecked to 3.6Gbit) which I believe is using a CAT 6 flat cable.

There's really not a lot of 5Gbit out there right now, except my two desktops using Aquantia 10Gbit PCIe adapters can support it (but are connected at 10Gbit).

I'd imagine 5Gbit may be more popular with WiFi 7, or maybe it will go straight to 10Gbit.  The thing is, 5Gbit adapters are basically as expensive (or more expensive, if you buy old enterprise 10Gbit cards) as 10Gbit, so not really worth it.

I was really hoping for a 5Gbit USB 3.1 Gen 2 adapter coming out, (as 10Gbit uses too much power for USB AFAIK) but so far, nothing.

Main complaints over on OpenWRT are the RAM being too small

@Alex I seem to remember something about 802.11be supporting 40Gbit-class data rates. Wikipedia, I think - that’s where I found the article. Also it may have been talking about a link simulation, not a real test. That would be using 320 MHz wide channels, I presume.

[Alex Atkin UK]

Yeah, seems so https://en.wikipedia.org/wiki/IEEE_802.11be

But then WiFi 6 is supposed to support up to 9608Mbit but in real-world usage 99% of clients support 2x2 MIMO at best and we have Apple and smartphones in general usually only supporting 80Mhz channel width - so around Gigabit at best throughput at a 1.2Gbit link rate.

Zyxel even said my AP in their internal testing tops out at 1.6Gbit max, despite it being 4x4 MU-MIMO.  So its anybodies guess how all this works.
I have hit 1.44Gbit on rare occasions at 2x2 MIMO 160Mhz with a 2.4Gbit link rate, but only on one specific client.

I've not even seen a 3x3 or 4x4 WiFi 6 desktop client adapter, they're mostly using chips designed for laptops so still 2x2.  So I'd take any maximum rate with a pinch of salt.  I suppose for a wireless bridge 8 MIMO streams on each frequency between two devices could work, but that's a pretty niche use case.

Even for WiFi 6e, it kinda makes more sense to use 6Ghz as a dedicated wireless backhaul, given the lack of 6Ghz clients, but then you have the lesser range compared to 5Ghz so its still not ideal.

It should, in theory at least, be able to double the speed of WiFi 6.  Although quite how they're going to pull off connecting to 5Ghz and 6Ghz at the same time in a mobile form factor without murdering the battery, I'd guess it will connect to one band and only connect the other during active data transfer?

So 256MB is too small now?  That's certainly curious.

I hit 500-600mbps with 1200mbps wifi 6 link with 2x2 MIMO on lan with desktop and between laptop openspeedtest server.

Yes, I bought it. Maybe it will get support from openwrt but no
