> not use it. A few things come to mind... - You can buy ethernet adapters... for iPhone/ipad/etc. Operations are so much faster, especially large downloads like offline maps. - many consumer devices suck wrt to wifi. For example, there seem to me ZERO soundbars with wired subwoofers. They all incorporate wifi. - also, if anyone has lived in a really dense urban environment, wifi is a liability in just about every wa…

> Why do macs show all the neighbor's televisions in the airplay menu? That's a feature that can be configured on the TV/AirPlay receiver. They've configured to allow streaming from "Anyone", which is probably the default. They could disable this is setting and limit it to only clients on their home network. And you can't actually stream without entering a confirmation code shown on the TV. When you stream to an AirP…

Adding cat5e or cat6 to each room is just a cost. Builders generally compete on cost.

It’s a cost that doesn’t show up on listings. There’s a surprising number of ways new US construction sucks that just comes down to how it can be advertised.

Unless I'm mistaken there are no requirements for what has to appear at all in real estate listings. Maybe some local regulations exist. I know where I exist the seller is required to provide an "energy audit", but I'm not sure there is any mechanism to enforce that.

> I don't know how 2025 houses are built but I would be surprised if they didn't have an ethernet jack in every room to a wiring closet of some sort. Not sure about coax. Speaking from a US standpoint, it still not common in new construction for ethernet to be deployed in a house. I'm not sure why. It seems like a no-brainer. Coax is still usually reserved to a couple jacks -- usually in the living room and master be…

i live in 2003 built house in usa. i have 2 x cat5e and 2 x coax (they are bundled together ) coming to outlet in every room. everything goes to (un)structured media enclosure.

I'm not saying there are no homes built with Ethernet. I'm just saying it's neither common, nor the norm. At least in the western United States.

Every doubling of the channel width costs roughly 3dB. Shannon's law strikes again!

Every doubling of the channel width doubles the Shannon limit* * An a gaussian white noise environment, which WiFi usually isn't in.

*If the bandwidth of the Analog Front End (AFE) and Analog to Digital Converter (ADC) / Digital to Analog Converter (DAC) doubles as well. In the real world the AFE of any wifi radio has a fixed bandwidth, with the ADC sampling rate and accuracy being fixed as well. The end result is that doubling the channel width in a wireless network requires a received signal strength that is roughly 3 dB more in real world devices. This constraint is quite visible in data sheets for most wifi cards like here: https://compex.com.sg/wp-content/uploads/2024/01/wle7002e25-...

Some friends live in a rental that they’ve decorated well. It wasn’t until multiple visits that I realized they had run Ethernet throughout the house. You can get skinny Ethernet cables that bend easily. If you get some that match your paint, and route them in straight lines, those can be unobtrusive. Use tricks like running the cables along baseboards and other trim pieces. If you really want to minimize the visual…

I did this years ago using the very thin (3mm, round) Unifi Patch Cables in white. Very clean and reliable, and getting 1 Gbit/s without issue. Another benefit is that I can cram 4 of them inside a single cable runner at the one spot I have to (no space for a switch). Where it's just one cable you run them bare and they look very clean. The old ones I have are still CAT5e, the newer ones they sell are CAT6 at the sam…

I wonder if you can buy a spool of this stuff.

At some point fiber and a few media converters at the ends will probably be the better choice. The connectors are much smaller too.
