The reason segmentation doesn't matter: the data already is going to merge in the router. Merging in the switch doesn't make the data talk to each other or get mixed up in the switch. That's not how the data works. It's discrete. The idea that you need segmentation because somehow packets leak to each other is what VARs hint at to sell VLAN services where none are needed. VLANs have great use cases, but avoiding the comingling of packets one device sooner than they will mingle anyway, isn't one of them.
For the video games: if the boys were gaming with each other, instead of online, and their game traffic stayed on their physical LAN and never went to the router, then that would make sense and physically isolating that for performance could make a lot of sense. But that's not how it works. Their games are online. So their traffic is flowing up to the router and getting in the way of your traffic identically whether you put them on a different LAN or not, it doesn't change anything.
At the end of the day, the data is not segmented where it matters, only segmented where it doesn't matter. Rather like buying a car and being told that it is redundant. Sounds great, right? But what if the only parts that are redundant are parts you can't use like a spare steering wheel in the back seat or a second glove compartment in the trunk?

I have not set up a network using subnetting like this before and wanted to try for a learning experience.
Doing a VLAN does all this, and more. There can't be anything new here compared to a VLAN. This is the "simplest possible scenario", all VLANs are built on this as the lowest common denominator of "LANing".
Alright I see what your saying. So basically a worthless exercise. Sounds like I should just use vlans if I want to do this. Btw most of my perceptions about how this works are from my studying. I passed the Network+ because they said subnetting and creating different networks to keep traffic separate will always improve performance and increase security, but make it less flexible. My home isn't going to change so I wasn't worried about the flexible part. It was also said that vlans will accomplish the same thing but just do it much differently. So I wanted to learn this other way of doing it just in case.

Potentially worthless, but maybe there is a value here that we've not found yet. But not worthless if it turns out to be good practice in evaluating needs!

No, you should do neither. VLANs are equally pointless here. All segmenting here has zero value.

Rule of thumb: if someone says something like that, but can't explain why it is true, it's not true.

@scottalanmiller said in Redoing Home Network:
Yes, it's segmented.... some of the time. But... why? What value does that provide? They are not segmented in the router. So the data all merges before doing anything useful.
So if my office is on port 1 of the router and her office is on port 2, all the traffic still merges? Her boss has hinted that work at home employees may need to be on distinct networks in the future, for some government regulation. So I wanted to get ahead and just do it from the start. I know I could use a vlan. So your saying the traffic still merges even if we are on different switches, connected to different ports on the router?

@scottalanmiller said in Redoing Home Network:
In your example, you keep mentioning segmenting and performance. But you don't state why segmentation of network traffic would be beneficial in this case (spoiler: it's not) nor why performance would benefit (spoiler: it doesn't.)
In my cert studies it was always that segregating traffic improves performance and to do it whenever you can.

Yeah that is true. I know I need to improve on that a lot.

Of course, you are sharing one network connection. Imagine if you have to spaces in your garage. Even if there is a wall in the garage dividing the spaces, they still merge in the driveway.

That's BS and makes no sense. To do that it has to be a unique network connection from the ISP, and even then, it can merge on your property still, just outside of your demarc. The Internet is all merged traffic, obviously.

@jmoore said in Redoing Home Network:

Yes, all traffic merges when you use the Internet. It either merges.... far from your house, near your house, or in your house. But it merges and it's pretty trivial to figure out where.
All traffic is merged, it's a 100% meaningless requirement. Like people saying that the need more Ether to breathe. It's a totally made up, non-IT concept.

Remember, never take someone's word for it, if they don't explain it, don't listen to it.

Got it thanks. I had the wrong impression here.

Well dang, thanks for the advice. I didn't have any details from her job, they just said that to her in passing.

Yeah I won't forget that ever. Thanks.

I've with JB - You should save the money and get an ER-4. The processor is the same.
POE can be done in the switches, so no need for that in the router.
The ER-4 is nearly half the ER-6.I already ordered the pieces. Thanks for your input though. I needed a router with 4 ports for my 4 rooms plus the incoming port. I plan to use and learn everything about it.
Do you really need four ports? I suppose if you don't have a core switch, and the switches in each room go directly to the firewall, then sure.

One of those things lay people say because they aren't clear on what computers are or how networks work. So people use buzz words that they've heard and try to make things up to sound impressive. Like how managers say "cloud" but randomly mean "hosted" or maybe "online" or perhaps "web" but never, ever mean "cloud."
The government might require discrete connections, but meaning discrete out to the ISP. But even that is silly. As someone who manages ISP networks, that doesn't do much either.

That was my plan yes. Router with 4 ports so I could directly connect a switch in each of the rooms. I'm being that's not a good idea.

Yeah I understand that. I guess I gave them too much credit. It didn't make sense to me but at same time I know I;m not too experienced, so I figured there was a valid reason and I just didn't understand it.

The ER-4 is nearly half the ER-6.Isn't POE also better in the switches? I thought Ubiquity used some odd DIY standard for POE, at least in the past.
It is not an "odd DIY standard", it is 24V passive PoE
It was used for years on outdoor wireless gear from Motorola. Ubiquiti, which got its start in the WISP market, used the common standard already in place for a reason. It let their get get added to existing towers.
