Ethernet at 50 and still not slowing down - a testament to the saying 'if it ain't broke, don't fix it.' It's remarkable how this old-school tech has remained relevant in an age of wireless everything. Makes me think of my tech stack, Java, monolith, sql db, etc. and it keeps serving all of my paying customers reliably, even though I'm not using the latest everything.

#122It's only a pity that things fossilized on 1500 byte packets. Yeah, we can compensate for that with hardware, but it's ridiculous to do 100G or even 10G in 1500 byte chunks.
Jumbo frames are a thing.
Never seen used in the practice though. One of problems AFAIK - most switch default to dropping jumbo frames. You can enable but if you'll left one unconfigured for some reason you will get hard to diagnose problem. The same with end hosts - they (inside a given L2 domain) should have the same MTU and if you'll left a box with the default MTU you got a problem.
To make jumbo frames easier to use switches should forward them by default and hosts should accept frames large than MTA (but send MTU sized ones).

#123I'd love to hear all the disruptive, trendy, innovative and blockchain-focused tech that'll cost me a fortune instead of relying on cheap ethernet. ^ The '/s' is implied.
I get you have beef with blockchain but it feels petty and intentionally detracting from the subject.
I get that you have a beef with an anti-blockchain heretics speaking blasphemy in the public square and are compelled by your religion to chastise them vigorously, but you aren't helping keep things on topic either.

#124The one thing I would really like for ethernet is a smaller connector. But one that is still able to handle self-made cables. So something like just throwing a Type-C connector at it probably isn't going to work.
USB-C would certainly work, you just need the right (wire) mounting device behind the plug. It's unlikely to be very slim though.

#125This is a comment for folks in homes with coax run for cable TV. Ethernet is great. I wired ethernet to most rooms in our remodel and set up wired access points or jacks in the office to connect directly to my computer. The speeds and consistency over wifi and mesh were remarkable. Especially consistency. We moved, and it's not feasible to run ethernet everywhere in our current home. However, whoever built the home r…
Also, check the phone lines. If it's recent enough build, it will use Cat5 (or higher, but probably not) for the phone lines.
One issue with that is that electricians can sometimes be brutal on Cat5 used as a phone line. I’ve had drops that were basically unusable as ethernet because some of the pairs were damaged, even though the phone pair in use was fine.

> We moved, and it's not feasible to run ethernet everywhere in our current home. However, whoever built the home ran coax to nearly every room in the house - it's a bit ridiculous How old is the house? If its more than 20ish years old running coax everywhere was a great choice. That would be before CAT5e cable so if they had went with ethernet cable instead of coax you'd be looking at 100 Mb/s. If it was built befor…
You can hire someone to run the cable for you, it's not a terribly hard job. The most expensive part is getting out there.
So keep an eye out for a neighbor who has an electrician doing work and maybe see how much to just move the cable.
Drones is overthinking it.

#127It still kills me that this name was used for a wired, rather than a wireless setup.
Ethernet is a protocol, it has nothing to do with the cables. WiFi operates using a slight variant of the Ethernet frame
Ethernet is a family of standards which encompass physical wiring, connectors, electrical/optical signaling standards, and logical layer standards. It absolutely has to do with the cables as well as the signaling.

#128Metcalfe, inventor of ethernet, predicted in 1995 that the internet would collapse the next year, because the underlying tech couldn't possibly scale. He ended up having to literally eat his own words. See: https://en.wikipedia.org/wiki/Robert_Metcalfe#:~:text=24%5D%...
Wow, a truly rare instance of literally eating your words!

I do this too and it is terrific, literally indistinguishable from ethernet. What’s amazing is you can run cable and MoCa on the same wire at the same time!
How does this work with both? Is there a defined band plan standard that cable operators know to avoid? Do you need to install a notch filter on the line coming into the house?

Oh, so you can connect several devices to the same "shared" coax cable around the house? How is it? Is it really 2.5gbps or is it like Powerline adaptors that are an order of magnitude slower than their advertised speed? :P
Yes. My setup is like this:
Fiber ONT/Modem -> Access Point -> MoCA adapter 1 -> Coax Splitter
Coax Splitter -> MoCA adapter 2 -> Switch -> bunch of devices
Coax Splitter -> MoCA adapter 3 -> Switch -> Access Point + bunch of devices
Coax Splitter -> MoCA adapter 4 -> Access Point
the MoCA adapters actually report 3Gbps+ between each other, but my access points only have gigabit Ethernet so that's my bottleneck.
There are different standards of coaxial cable (RG-6, RG-59, etc). If you see low speeds with MoCA, it is probably a cable problem and not an adapter problem.
