Unfortunately, many smart TVs use 100 Mbps RJ45 ports, so WiFi is usually faster. Some TVs allow you to plug in a USB to RJ45 adapter, but most of the USB ports are only USB 2 speed, so the practical limit is 300 Mbps. Some nice ones have USB 3 ports enabling 1 Gbps through an RJ45 adapter. I wish the manufacturers put at least gigabit (if not 2.5 Gbps) RJ45 ports on TVs.

Excuseme, what kind of content do you have with more than 100mbps bitrate?

Exactly. Streaming a 4K Dolby vision blue ray remux that I legally own on my NAS uses 60-80mbps.

I had my mileage in wifi/routers development and I will say you just a proverb: "The one who knows how wireless works, uses cable." ;) When renovating an apartment I have put a shitload of ethernet sockets everywhere, there is no place in 80m2 apartment, where you would be more than 2m away of nearest (including toilet) and as 4 of them were not enough behind TV, I have added a router there.

The built in port has DMA. USB to Ethernet adapters don’t and have to go through the CPU first. You’re stressing the CPU for bandwidth you aren’t actually using.

Scientifically, of course you are 100% correct. But does it really matter if I can install a 3 satellite mesh and get 200 Mbps over WiFi even at the biggest “dead zone” in my home?

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)?

Because it's less fun to watch.

I work with several low-voltage guys on different jobs, both new development and retrofit. It is exceedingly difficult to find good cable guys. Running parallel to romex, staples through the middle of the cable, minimum radius as a non-existent concept... Like you say, the competency is the hard part to find. And before anyone adds on with 'lol pay more', they try. The people just aren't there.

Almost all homeowners can't pay more than commercial jobs (for the same amount of billable work). Ergo, if they can, tradespeople take commercial jobs. Which leaves residential tradesperson as something of a lemon market. (And I wouldn't want to put up with one-off job, haggling about payment, if I had commercial options)

Post COVID burnout (or maybe it’s cognitive dissonance issues?) seems to be a thing too.

Just finding a contractor or business owner able to think clearly is reaching near impossibility.

Like on even the most basic things. It’s quite concerning.

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."

>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.

Yup, which lately is often much harder/riskier than DIY if you already know how to DIY.

I've always wondered if that's the old glass insulation itself, or the accumulated mouse-poop-dust embedding itself in the microscratches and freaking out your immune system.

From the one time I blew in insulation without wearing a full Tyvek suit, I am confident is answering that it's the glass. That was an itchy lesson. (I wouldn't be surprised if there was a mouse poop factor along for the ride after long enough, though)

A lifetime of accumulated pollen/dirt/mousepoop does add some extra fun though in my experience.

The reason fiberglass is itchy is because it’s piercing the epidermis. It’s basically a pad of brittle micro hypodermic needles. Add those two together, and it gets extra fun.

> 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…

IMO sounds crazy. Can't you just step on the wooden frame instead of the space between them?

Sure, but don’t slip/screw up, or you’re going to have a very bad time (and a lot of expensive fixes to make).

If you’re up there a lot or doing a lot of things, it’s also exhausting paying that much attention. And inevitably, you’ll screw up.

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…

MoCA 3.0 actually supports 10gpbs.

> 1gig is still the standard for wired A lot of people already get more than that from their ISP. I had at least 2.5g on every consumer product from the past 5 years. Small businesses use at least SFP on the floor level. Yada yada yada. Point is it's probably a regional thing.

You never visited Germany, aren't you?
