If the author is hitting 940 Mbps on a daisy-chain, either the echo cancellation or the frequency diversity on these chips must be lightyears ahead of standard DSLAMs. Does the web interface expose the SNR-per-tone graph? I suspect you would see massive dips where the wiring splits to the other rooms, but the OFDM is just aggressively modulating around them.
I don't think there is anything too fancy compared to a DSLAM. It's just that DSLAM are low-frequency long-range by design.
Numbers for nerds, on top of my head:
* ADSL1 is 1Mhz 8Mbps (2 kilometer)
* ADSL2 is 2Mhz 20Mbps (1 kilometer)
* VSDL1 is 15Mhz 150Mbps (less than 1 kilometer)
* Gigabit Ethernet is 100Mhz over two pairs (100 meters). It either works or it doesn't.
* The G.hn device here is up to 200 MHz. It automatically detects what can be done on the medium.
> It’s the normal procedure to buy things from Europe since Brexit 2020. It’s actually quite shocking that Royal Mail still hasn’t updated their tracking system to be able to give a status “waiting on import fees to be paid online”. They had 6 years!
Wow.
It’s no coincidence those that championed Brexit are those that wanted a weaker Europe and weaker U.K.
That’s why the majority of tax payers were against it, the majority of educated people voted against it, the majority of working people voted against it, the majority of people alive today who voted voted against it
Yet we still got it.
In the mean time we should move closer when the opportunity rises.
The RJ11 panels on the wall were replaced with RJ45, crimped everything. Took a full day of carefully pulling wires but in the end I got gigabit all over the home.
The next owner will probably call me an idiot for using CAT5E in 2019.
There might be some market for a simple point-to-point device sold by the likes of Argos, zero config and including all the right cables already, aimed at people who can't or won't upgrade their cabling but want to enable their kid to play Fortnite.
But... there is no clear patent protection available, so as soon as someone successfully creates and markets that device, the Tiktok Shop clones will appear.
It's really not that simple when you realize that the average UK flat has 3+ sockets and the average house has 5+ sockets (speaking from my own experience). Some daisy chained and some direct.
Besides, a lot of people are renting and cannot touch their wire.
Nobody's going to complain about a backwards-compatible upgrade (you can put phone sockets back when you leave - nobody has to know there's cat 5/6 behind it).
Can involve taking up floorboards and drilling horizontally through beams, plumber style. Or cutting slots in masonry with angle grinders. Sometimes there are existing wires you can tie to and pull through, sometimes the existing wires were stapled to the walls.
On the bright side everything about the ethernet wires and connections is trivial. Like demo to a friend in 20 minutes and let them walk off with the toolbox and they'll be fine wiring their house, if the construction style is amenable.
One of the problems I had was a kinked conduit where concrete was poured on top, or at least that is what I assumed. Was a bit difficult to get the “knot” (where the phone wire was connected to the CAT5E) through that spot.
I tried the same approach to replace COAX cable with CAT but the tie just broke off like 10cm before the socket exit [1], and CAT is stuck there now.
I have a suspicion that pulling fishing line first is the right play if you can manage to connect it to the old wire. Flexible, very high tensile strength, small.
However, I wonder why it seems G.hn is only available in the form of adapters, and not as e.g. a PCIe NIC.
What I've seen done recently to work around this is to combine your custom chip with a standard Ethernet NIC on the same board. The computer just sees an (off-the-shelf) NIC that's always connected, and all configuration happens via IP by browsing to a specific private IP (this kinda insists on NAT though).
As a random aside - I've been surprised by this recently. I got a new shiny Wifi 7 router(TPlink BE550) and my Samsung S24 Ultra can sustain 2.2Gbps over wifi, both to and from the router. At this point I'm not sure if that is the actual limit or if it's limited by the 2.5GbE port on the router since that had my NAS connected to it and I was testing transfer to and from it. And it wasn't like an inch from the router either - it did it while in my hand, on the other side of the room with me sitting on our sofa.
For a lot of homes, that's enough to provide good-enough internet throughout the building.
The issues arise when you've got a larger building, thick walls, lots of things competing for the same frequency band, a less great router, or you need the very lowest latency.
It often isn't - it's just magic like TCP/etc that is doing its job and making it feel that way for bulk non-interactive transfers. But get those people on a Zoom call or anything real-time and it'll be painful (double pain if they've subsequently got terrible bluetooth headsets and/or accidentally use their laptop's internal mic).
Doesn't help stupid ISPs split their 2.4GHz and 5GHz bands on separate SSIDs so now devices can't switch automatically and you've either got people constantly hogging the 2.4 band or barely trying to hang onto the 5GHz one in conditions where falling back to 2.4 would be appropriate.
You can have the shittiest link possible with lots of dropouts and still get a decent speed test result because in between the dropouts you get max speed and TCP/etc is designed exactly to smooth over such packet loss, and browser-based tests aren't able to get low-level UDP access to defuse that.
Yet such a connection will be unusable for anything real-time, think gaming or videoconferencing. That's why so many people's connection still stutters on Zoom/etc calls - the "good" connection and super fancy router their ISP sold them isn't actually that good despite speed test results being satisfactory.
I heard the state of the wiring also wasn't great, sometimes apartments had twisted pair wires, while some straight wires, some only have 2 or 3 out of 4 wires connected, etc.
Good to know this technology still exists.
The law says one person can't stretch a cable over to his neighbour, because they would need a licence for that (although if you did do that, who would know?).
There is a separate cable network, again one operator (Virgin), who don't lease it out.
If you only have four wires available, it will usually still work at 100 MBit.
I'm currently running MoCA over spliced coax as part of the local connection and not amused by the 5ms latency on it. Also running 100mbit over cat3 I found in a wall which does work, but cat3 in another wall can't hold 10mbit. That link actually can hold 70mbit of vdsl but after a nearby lightning strike slagged various hardware I've moved the vdsl modem back to the BT wires entry point and run the output through some fibre.
And there's a wifi bridge between two other points. And some ethernet running outside the building. Previously also ethernet-over-mains that I might bring back now that I've learned what spanning tree protocols are so the periodic reboots they inexplicably require can be tolerated transparently.
Also the connection to the internet itself is crap so bonding vdsl, starlink and 5g through the openmptcprouter project. Just lots of redundancy and self healing hacks all over the place to give an observably solid connection.
Which is a rambling way to say that if you're in Britain and your network connection brings you sorrow, it can be forced to be acceptable with application of more time and money than other countries require.
I've had powerline adapters with uptimes measured in years (basically in between power cuts). I think yours might be defective. They absolutely do not require reboots.
As a side note - it's quite difficult to find white fiber cables. They're all bright colour so that nobody cuts them accidentally but I don't want a pink line running along the walls haha
It is flat and thin enough you can stick it on top of skirting boards/etc with tiny dabs of hot glue.
That's nonsense. Not in a new house. Maybe one from 20 years ago.
Anyway nice find. It's always annoying when there's a product that you know should exist but simply doesn't.
I'm currently trying to find a reasonably priced Bluetooth Auracast receiver so I can play audio to multiple rooms from my phone (no way am I investing in Sonos after all their bullshit).
There should be loads of these but the only ones I can find seem to be battery powered wearable devices aimed at tour groups, or hundreds of pounds.
My internet is pretty good, I can easily saturate my (rather dated) WiFi at about 30MB/s. But Steam downloads are extremely slow for me (can't remember the numbers but much less).
I always assumed Valve themselves were just stingy with bandwidth. Something else funny going on?
Considering Valve has an incentive to make downloads fast (= more revenue), it's likely your ISP is being stingy in this case.
Ignoring the horrible taste of our forebears that were putting TVs where they don't belong, that does enable carrying gigabit ethernet using MoCA technology.
Ok, the writer could be renting a house and not wanting to do that. But sincerely, in Portugal, the landlords couldn't care less. Maybe in the UK, they really, really love their phone sockets and don't want to replace them, don't know.
I had a phone socket in that room and I had already discussed the possibility of converting it into an Ethernet socket but decided it's not worth it because everything ended up in a cupboard far away from my router. These adapters would have solved the problem nicely!
By the way, I have more fun stories. The cabling in my current house (which has Ethernet sockets) is still miserable. I spent a year working with my PC over USB tethering to my phone until I finally called an electrician to find which of the 11 dangling cables in the cupboard went to my office...
One day some wires in there were slightly moved and the internet got disconnected because they were badly crimped. Nothing was working so in the end I got an RJ45 connector and managed to get the wires in there.
I think this is true in the sense of there's no regulation it's just up to the developer, but my house (new build, 2021) has an RJ45 patch panel downstairs with 4 ports that lead to 4 areas of the house.
This was actually a surprise to me when I got the place because when I was speaking to the sales associates they had 0 clue what I was talking about when I enquired about network cabling. If I had known they were installing it as standard I'd have asked for more ports in more rooms, but hindsight...
But yeah, there's also 4 phone sockets as well, which I don't use. This solution might be interesting to try out, but phone sockets are in the same place as where the ethernet sockets are and I've no real need to expand in those rooms right now.
Andrews and Arnold[0] offer gigabit, but I'm not surprised the author hasn't heard of them; they never advertise.
This sounds a bit farfetched to me. I'm 40+ and lived in the UK all my life. Growing up we only had 1 phone socket in the house for the first few years until my dad got an extension put in upstairs. I've lived in multiple cities since then and no flat or house I've lived in has had more than 1 phone socket including the house I eventually bought and live in now (which is not small by most UK standards).

Which might well be true where he is (ie he's limited to the equivalent of shared HFC or xDSL), but certainly isn't true everywhere.
I've had gigabit fibre (full duplex) in London since 2016, and the building had it before I arrived. It also has incredibly low latency to the major data centres of London, and not a lot more to most of western Europe.

> One peculiar thing from the UK: Internet providers don’t truly offer gigabit internet. They have a range of deals like 30 Mbps – 75 Mbps – 150 Mbps – 300 Mbps – 500 Mbps – 900 Mbps, each one costing a few more pounds per month than the last.
Gigabit is so much more expensive (obviously it's gone down a lot). In London 2016, I had ADSL broadband at 16 Mbps for £12/month. That building didn't have fiber at the time. When fiber finally happened... it started as 30 Mbps fiber for so much more money.

If you're served by a niche fibre provider (e.g. Hyperoptic, Community Fibre) then you're golden.
There's Virgin (think Comcast) with paltry upload speeds due to the cable tech. Understandable though not ideal.
Then there's the OpenReach full fibre network with paltry upload speeds due to... ??? there appears to no good reason, other than not wanting to cannibalise their leased line business. Does anyone actually know why they don't offer a symmetric product like the niche fibre ISPs?
