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…

What hardware adapters are you using?

I use goCoax adapters and recommend them. I haven't tried any other manufacturers.

That's Aether.

So it is, I didn't know that. In that case the other poster point stands, I'm guessing they used the word to indicate the magic of the network?

Metcalfe, 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%...

I'm curious why the audience would not accept him eating the paper pulp in large cake form? Perhaps because he couldn't reasonably eat the whole cake in front of them (and thus his words)?

> He had suggested having his words printed on a very large cake

I guess that would just be eating cake, so not really any form of penance

I totally disagree with the idea that ethernet is "going strong".

On the high end, it is a fragmentation mess of high speed (100Gbit+) technologies and mac/phy's.

There is no midrange at this point.

And the low end is price discriminated such that the Nbase spec couldn't even mandate all of 1/2.5/5/10 as required as part of the spec with the speeds being automatically selected based on cable quality.

And its largely dead because its to expensive and Wifi is more convenient.

> 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…

Should I be surprised that the reactions posted here range from "I stretched a cable across the ceiling like two tin cans and a string" to "I will fly a drone into my attic". Instead of: "I took my $500k/year tech salary which I formerly spent on Teslas and cardboard apartments and just hired a competent electrician or other tradesman to pull cable to every room."

You'd have to pay me that kind of money (amortized) to deal with vetting/hiring/managing/scheduling/QC'ing someone else and their work.

Intel needs to stop gouging customers for 10GBe NIC cards because they've got all the patents on the technology. Greed is _so_ ugly.

what is the primary use you would have for them? do you have a 10GB connection? if so, very lucky

I want a network with that much bandwidth but prices are astronomical.

I'm still using the coax for my OTA antenna

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 forwa…

Jumbo frames are used constantly in practice, just not often on the internet. They're common in all sorts of networks, especially enterprise and storage.

If your switch is configured on defaults and not running a for purpose config, you probably don't need jumbo frames.

I've been dealing with twisted pair cable since the mid-90s and I've never seen Cat 4 cable anywhere, commercial or residential. Cat 5/5e both support GigE. The primary difference between FE and GE with respect to cabling is th…

I thought gigabit required all four pairs, or am I missing part of what you said?

For typical Ethernet sure. Although there are newer standards that can use a single pair (1000Base-T1). They are very range-limited though and not what you would normally install in your house.
