I live in a house nearing 20 years old, and was incredibly pleased when I moved in and realized that all the phone jacks in this house were backed by CAT5, and if I was willing to invest the time (which I am), I could have at least one Ethernet jack in each room, and a pair channeled up to the attic as well. My only regret was they stripped way more than needed and didn't leave a lot of wire available, but enough tha…

Implicit QoS - each device has a max 1GBps share of the 2.5GBps connection. Most hardware can't handle more anyways.

That's exactly how >1Gbit/s connections get sold. Hardware with multiple high-speed ports is very expensive, so typically you have 1 2.5G/10G port LAN port and all the other ports are 1G. So they say you can have multiple concurrent 1Gbit/s streams.

This is a comment for folks in homes with coax run for cable TV. Ethernet is great.

If there's already a coax cable run what's stopping you from running an ethernet cable alongside it or replacing it?

Laziness. I’d much rather spend $100 on gizmos than spend hours on a home improvement project. And these projects are never as simple as they at first promise to be.

> very expensive 10g For me it's just 2€ more expensive than the standard 1g plan. It's really unfortunate to see how bad internet prices are, especially in the US and other countries with ISP monopolies. The only reason my internet is so relatively cheap is because early on there was a lot of competition in my country.

That isn't what is expensive. If you get 10 GB, the question is, then what? I have bidirectional 1 GB plugged into a $200 EdgeSwitch, which then feeds Cat 6 throughout the home ($100/500 feet). This then filters down to $20-30 unmanaged 1 GB switches elsewhere. The whole thing is under $500. If I wanted to go up to 10 GB I don't just need to change to a $2K~ EdgeSwitch, I also need to run fiber/6E to be able to deliv…

Correction: you can usually run 10Gbit/s over CAT5e if the cables are not too long, so you probably won't need to replace your cables. But the hardware is indeed expensive.

> 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.

Nah, you're in a very small minority. Most households have few hundred megs at most

You’re probably in US. Meanwhile in Switzerland people are enjoying 25gbps internet: https://www.init7.net/en/internet/fiber7/

> 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…

> 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 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 that GE uses all 4 pairs where FE used only 2 pairs. The difference between 5 and 5e cable is pretty negligible, and the GigE standard only requires Cat 5, not 5e

With respect to Cat 4, you're confusing the signal bandwidth and data rate. Cat 4 supports up to 20 Mhz signal bandwidth. It can be utilized by either 10BASE-T (10 Mbit/s) or 100BASE-T4 (100 Mbit/s).

If there's twisted pair data cabling in the home at all, it's probably suitable for GigE. Otherwise it's likely RJ11 phone cabling that's not typically going to be in a home run topology.

That said, the standards are pretty forgiving over shorter distances. Here's someone claiming they got GigE speeds over Cat 3 cabling in an older home:

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.

Gosh, I cannot imagine what would be unappealing about the opportunity for a tradesman to devalue the price of their labor and experience the small-but-inherent risk of catastrophic injury any time a ladder is involved in exchange for the chance to pick up a spare tenner…

(Beyond that, even if they’re already in the area, by the time they pull up the truck, load and unload the ladder and actually do the job, the per-minute rate is probably already a fair bit worse than what they would earn from real customers - it may seem to you like you’re offering an easy job at $10/minute, but it’s probably a tenth of that all in from their perspective.)

It's only disappointing that the most common standard nowadays is 1GB/s. I feel like there is a big gap and standards like 2.5GB/s or 5GB/s were somehow ignored and 10GB/s is a big jump up (also price wise)

2.5 Gbps is pretty common.

Then please find me a 2.5G 8-port switch with PoE for $100?

Considering that you can make > $20/hr flipping burgers in Seattle I'd say you are off by an order of magnitude. No reasonable skilled tradesman (or even unskilled handyman) is doing anything for $20. It's borderline insulting. They have expenses, fuel, insurance. Most charge $100 as a trip fee.

I think you missed important details in their post:

>> tasks I wanted done that would only take someone with the right skills and equipment a few minutes

>> tasks that are near them

The idea is, you're someone handy with equipment, and someone down the block wants lights installed. So you walk there with a couple tools on your hand, spend 5 minutes doing it, and earn (say) $20. Instead of just sitting at home and watching TV when you're bored. If you don't feel like it then you just don't take the offer up.

This is not meant to be an alternative to your day job. It's just intended to be something extra you can do when you're home anyway. If transportation and fuel and other costs would factor in then you just wouldn't do it.

It's in no way insulting, it's an opportunity for anyone that wants it. I'm not a handyman but I'd definitely do this from time to time if (say) my neighbors needed computer or coding help for a few minutes.

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

Probably NAS transfers or similar.
