Jumbo frames are a thing.
Jumbo frames are not a thing on the internet. The internet has fossilized at 1500 byte MTU.
This 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…
If there's already a coax cable run what's stopping you from running an ethernet cable alongside it or replacing it?

Another way to get something supposedly more stable than wifi when ethernet cabling is not feasible is to use your house's electric wiring and run data through that. There are kits which offer data rates in gigabits (although based on a few reviews I read the actual speed vary greatly). https://en.wikipedia.org/wiki/Power-line_communication https://www.tp-link.com/us/home-networking/powerline/tl-pa70...

Cool! I have the same issue with unused coax cables between every room, and was planning on replacing them with ethernet cables. In my case it's feasible without breaking down any walls. Does this work even with splitters?
It'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.
Yeah, what's with that? I looked into enabling jumbo frames on my home network (just for fun, I don't really need it) and it seemed horrendous as those packets could end up on the internet and probably wouldn't work.
It still kills me that this name was used for a wired, rather than a wireless setup.
From the article on the origin of the name.

I'm pretty sure a switch is just an L2 bridge but still uses the ethernet address management mechanism (mac addresses) not the L3 IP (or whatever) address / routing mechanisms. Modern ethernet, on wires anyhow, is very different from the original one with a shared broadcast domain. Ironically, wireless networks are still very much like the original "you've got a piece of wire and everyone yells into it after listenin…
L3 switches are absolutely a thing, they allow communication between different VLANs on the same hardware without needing to go through a router.
I have layer 3 switches doing eBGP.

In 2023, there are very few uses for home users that will exceed what a 1G connection can provide. But please enlighten me about where you think you've "heard this before"?
> In 2023, there are very few uses for home users that will exceed what a 1G connection can provide Video games are getting bigger all the time. The latest Call of Duty apparently is 200GB. On 1gbit you are limited to 125MB/s downloads (assuming zero overhead) that's almost a half an hour to download. PCIe4 SSD's are capable of write speeds of about 7GB/s and PCIe5 SSD's are just hitting the market with even faster s…
I'll be generous and give you a hint: it doesn't mean none.
But your example also has great relevance to the "familiar" sentence in my original comment which was:
> 2.5G is rapidly approaching, if not already past the point, for a lot of people where a single machine will never use all of that capacity, and the advantage of higher total bandwidth is to support multiple people doing high bandwidth tasks.
I italicised the part that I knew people would somehow ignore in my original comment and I've done it again, because obviously once wasn't enough.
Here, let me pull out the important words yet again just to make it really clear:
> for a lot of people

The thing is, the moment a new upper bound becomes available, developers find a way to use it. It’s like the freeway problem that adding more roads ironically adds to congestion.
Take storage, the greater the storage capacity of media increased, the larger game assets became. The faster CPUs and system memory became, the heavier our operating systems and desktop software became.
Likewise, the faster our internet becomes, the more dependent we will become on streaming high fidelity content. 4k on a lot of streaming services is compressed to hell and back to work with people on slower internet connections. And much as Google Stadia was shutdown, video game streaming services aren’t a failed experiment. Plus even with more traditional services, how many of us roll our eyes at multi-hour download times for new games?
Once gigabit internet becomes the norm (it’s common place in a lot of countries already, but it’s not quite the norm yet) then you’ll see more and more services upscale to support it, and thus others on the cutting edge of the tech curve finding that gigabit internet isn’t quite fast enough any more. And that will happen sooner than you think.

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 before 1995 you'd be looking at CAT4 and under 20 Mb/s.
I've got an ethernet cable running between the two rooms that are farthest apart in my house, but it is kind of ugly. I just screwed in cup hooks or nailed in nails at an angle on the walls up near the ceiling and draped the cable over them.
The right way would be to run it through the crawlspace or attic. I don't want to crawl around in the crawlspace, and my attic is the kind that if you aren't very careful you can put a foot through the ceiling of the room below, and has a bunch of blown in insulation that would probably make it even harder to get around so I don't want to try that.
I've wondered if I could run cable through the attic without actually going into the attic. Open the top of a wall below and drill up into the attic. Attach the cable to a pole and use that to push it up into the attic several feet, with the end of the cable tied into a loop.
Then send a drone into the attic, fly it to the pole, hook the loop, detach the cable from the pole, and fly the end of the cable over to the attic access hatch.
Then do the same with a cable at the other end. Splice the two ends together.
Is that reasonable feasible or is it just crazy?
