Sorry to be pedantic here, and I know this video is old, but your description of an ethernet switch actually is that of an ethernet hub. Hubs operate solely on layer 1, the physical layer. That is to say, they duplicate incoming signals electrically and do no routing. Hubs are practically nonexistent in this day and age as they're pretty much useless. Regular, unmanaged ethernet switches operate on layer 2, the data link layer. It routes transmissions to the port they're intended for by identifying the MAC address of the next hop as specified by the previous hop. Layer 3 switches are where the line between switch and router starts to get blurry, and many managed switches are layer 3 switches. These operate on logical addresses (typically IP addresses) more than hardware addresses. These are capable of advanced routing, as they can operate on layer 2 and 3 as needed. For example, a server could be connected to a layer 3 switch via multiple physical connections and the layer 3 switch would be able to provide load balancing and failover functions.
But I know what you're referring to with having too many devices on it at once - If more than 1gbps of traffic is trying to make it through to your router, it's going to slow down, as the speed it can pass network traffic along is limited by the physical layer speed (in this case 1gbps on each port. This bottleneck would exist for a layer 3 switch as well, unless it were connected to your router via a faster physical link, which in this case isn't possible as the pi also operates at a gigabit maximum.
I don't know if you addressed this in another video as I've yet to accomplish watching all of them, but I thought I should throw that out there.

6: 52 But that's just wrong. Ethernet switches do rout traffic, that's why they are called switches not hubs. Ethernet hubs did just duplicate traffic without doing any routing. Hubs are OSI model L1 (physical (electrical) Switches operate at layer 2 data link layer and look at ethernet frames and pick out source and destination mac addresses and send the traffic to the intended ports. Other ports do not see the traffic that was not intended for them.
It is simple to prove this by passing 4 connections through a gigabit switch running iPerf. Just imagine if a 48 port (or larger) switch was bound by 1gbps throughput, why on earth would they put a 10gbps uplink port on something like that?
Hubs were common in 10mbps days, they found some use in 100mbps equipment, the original gigabit standard included half duplex gigabit hubs but I don't know if a single one reached market outside of compliance testing labs.
An odd bit of trivia, passive hubs did exist, they needed no external power.

You've given me some things to think about. I knew about the powerline LAN units, but got distracted, plus thought I read that they had a degraded (degrading) signal effect/capability. But will solve a few issues versus cabling. Discovered this site as I found that with VPN full time (Kill Switch on, my laptop cannot -see- my PC - does not appear in the Network list. I do not use Microsoft accounts - which would make this easy, I think. I need a means to have VPN on (both PC and laptop) but be able to access the PC from my laptop. I had this ability working for a while, then either the Kill Switch or some other change now blocks the process. Thought I could do something though the VPN software (Surfshark, but haven't discovered a way. Any ideas, anyone? MS took away the HomeGroup back in the fall +/- - grrr!

Excellent information; but I'm going to have to watch this five times and take notes to comprehend what I need to do. I have Google Fiber and their mesh Wi-Fi, but I think I'm going to start cabling the laptop directly into the fiber box. More speed - easier to do what Rob is doing. or close to it. :)

Rob, your link rob. brax. me no longer connects (We can-t connect to the server at rob. brax. me. I have purchased the VPN $89, but can't see a valid link to the VPN build software. I'm in the UK but have a Pi4 ready to go, can you help point me in the right direction please?

What are the maximum speeds I should expect out the gate with this vs a usg with threat management running (85mbps? Just wondering which is the better option right now. If I went with the USG, I'm planning on a unified switch and access point to run their controller.

Thanks for another great video Rob. As a fellow ham, do you get interference from the mains electric routers? This is a big problem here in the UK. Those mains routers make a hello of a lot of noise!

Amazing content, thank you! Could you please review some home security systems or talk a bit about how to set up home security without loosing all of your privacy and having to become a tech expert?

Have converted an old laptop into a router with Linux installed on it, controlling everything coming in or out with Pihole and DoH running on it. No DNS query leaves my house unencrypted.

is the purpose of the pi-hole, just for your devices on the NON VPN routers? If you have a VPN router setup with a VPN that has a tight DNS there would be no need for the PI-Hole correct?
