For what can I use this "Ethernet Network Splitter"?

[Eldin]

I bought this Ethernet Network Splitter almost a year ago because I needed to connect 2 devices to 1 Ethernet port on a router.
That failed to work.

https://steamcommunity.com/sharedfiles/filedetails/?id=2154932288

I can't figure out for what is this "Splitter" used for.

These are the things I tried:

• Plug in the male end into a router.
  Then I plug in 1 device into female end (internet works)
  As soon I plug in 2nd device into female end internet on both devices stops working (they show that network cable is not connected)
  
• Plug in male end into PC
  Then I plug in Ethernet cable from a router into female end (internet works)
  Then I plug in another Ethernet cable from another router into 2nd female port on andapter. (On PC it shows Network cable disconnected)

To recap it:
If I connect 1 Ethernet cable to any of the 2 female ports, interrent works

But if I connect 2 Ethernet cables to both female ports, internet doesn't work

So, how exactly do I use this Ethernet Network Splitter?

[iceman1980]

in order for a switch to find a IP bound to a MAC address it sends out a ARP request that request is received by the switch where the switch then forwards that to a router in that network segment. A static route between your two routers would allow them to communicate ignoring the the switch.



So your Pi-Hole DNS address should be in the 192.168.50.0 /24 segment.

Connect the two routers together and make a static route between them. Skip the switch between the routers.

Oh crap. I forgot a very important thing.
In order for Raspberry Pi running OpenWrt to do the network bonding, it has to see different network interfaces.

So, when I connect 2 routers and Raspberry to the Switch, would Raspberry see those 2 Routers as separate interfaces and allow me to bond them?

And I doubt that this would work, but could Raspberry send back bonded connection to the Switch via that Ethernet cable and from Switch to other devices? (Because if it can't do that then I could benefit from bonded connection only while connected to Raspberry's wireless hotspot.)

Make sure you are buying a Gigabit switch and not a Megabit one. That $10 switch will likely not go any faster then 100Mbit.

I don't really need gigabit switch because my internet speed according to speedtest.net (when nobody else is connected) is about 10 / 0.5 Mb/s
And cousni's speed is about 12 / 2 Mb/s
So when I bond them the fastest I ever achieved was 22 / 2.5 Mb/s

So, 100 / 10 Mb/s switch is much more than enough for me.

Do not confuse megabit with megabyte.

100 megabit = 12.5 megabyte

100mbit is really slow. Pay $5 more and get a gigabit one or you will regret it later. This isn't jsut for your internet speed, it's also for moving data internally in your network. Your HDD can push data ~15x faster then a megabit switch can handle, it will push up to 150-200 megabyte/s.

Even during normal internet usage on your not so fast network the 100mbit switch will be a bottleneck.

I'm not confusing those two.
My download speed is 10 megabit per second.
That is 1.25 megabytes per second.

So the total bonded connection is 22 / 2.5 Mb/s or 2.75 / 0.31 MB/s

I usually buy stuff from Gearbest because shipping cheap.
Shipping for the Switch I listed on previous page is $1.22,
But on Amazon is about $54.

Then the OpenWRT needs to be connected to both segments which will still need a Static route between them. The switch has nothing to do with Layer-3 forwarding. The layer 2 should live inside your "local network"


Then you should connect your Load balanced routers to the two separate addresses. So

Load balancer --> Cousins network & your network they're then forwarded down into -> your DNS blocking Pi-hole that then acts as the DNS for your main computers to connect to. Your computers / network needs to be on the same segment as any other devices you want to be able to eliminate the IP overhead. forwarding outside the network.

Your PC (192.168.50.0 / 24 subnet) needs to be assigned to that subnet. Your PI-hole needs to be assigned an IP in the range 192.168.50.1 - 192.168.50.254 this then acts as the DNS server receiving and responding to DNS Requests from the internet then scrubbing that data and removing / ads and other trash.


So your Pi-hole (192.168.50.2) for sake of sanity and ease.)
FTP server (192.168.50.3)
Your computer 192.168.50.4 - 192.168.50.254 as your next part of the network.

Then your load balancer needs to see both
192.168.50.1 (Main ASUS router)
192.168.0.101 (Cousins router) So you'd then need a Static route on the load balancer to be able to see both the 192.168.50.1 network and the 192.168.0.101

[Eldin]

This got much more complicated than I thought it'll be

I never did anything with Static routes before.
I'm a total noob with this (I just installed OpenWrt yesterday)

So, I connected my OpenWrt Raspberry to Asus via Ethernet and to Tenda via WiFi.
It looks like this
https://steamcommunity.com/sharedfiles/filedetails/?id=2155757318

So if I buy a switch and connect both routers to switch and connect switch to OpenWrt and do the Static Route thing, I should be able to see both interfaces as LAN?

How would I configure this part then?
https://steamcommunity.com/sharedfiles/filedetails/?id=2155758143

My original plan was to follow this tutorial
https://www.google.com/amp/s/sidslab.wordpress.com/2016/05/19/load-balancing-home-router-with-raspberry-pi/amp/

But because for some reason raspberry pi refuses to recognize my Ethernet to USB adapter, that failed.
Then I thought that I could do it with that Ethernet Splitter from the Original Post, but that failed too.

Now the only option is with Switch and those Static Routes.

please use imgur for images I distrust .cc domains. Especially when those pages have embedded Adware.

Is it ok if I upload like this?

yeah thats fine. Right now I'm ordering a Raspberry Pi fed up with the in app adverts *flips the bird* at microsoft.

[Eldin]

I'm going to sleep now. It's 3:49 AM here.
I'll probably order a Switch tomorrow.
Which one is better from those 2 I linked in post #13?
I'll send you a friend request because I'll definitely need more help with configuring this when get the Switch.
And thanks for the help.

Edit: Ordered the gigabit Switch
https://www.gearbest.com/modems/pp_009852032086.html
It should arrive in 3-4 weeks.
We'll see then is it possible to make this work.

Basically what it does is it has 2 inputs which can both talk at half speed.

Does this matter that only 10Base-T hubs exist?

[_I_]

there are a few 100bt hubs
ex. https://www.cnet.com/products/advancestack-100bt-hub-12txm-w-mgt/

hub send all data everywhere
switch only sends data to the destination port

its cheaper to make a hub since it doesnt need ram to remember what macs were used on which ports

[Pocahawtness]

There is a lot of misinformation in this thread. The device is a simple unit to combine Ethernet from two devices by simply linking the ports together electrically without any chips at all. It allows you plug say two printers in to a single port on a router. You are basically sharing a 1gbps bandwidth between the two devices but you will get data collisions. With the increased collisions they are best used on relatively slow devices like printers or devices or devices that are only used one at a time. Also these are not advisable with long data cables. Honestly a proper hub or switch is so cheap these are pretty pointless.

That is why I said bidirectional communication is not recommended. CSMA/CD will try to mitigate it but it will be constantly doing a "wait random some N number" before retransmit. Hubs are also no a good option due to lacking the ability to perform bidirectional communication.

We refer to hubs as Half-duplex communication
and Switches are Full-duplex.

If this splitter actually works as Bad Motha explained tnen both claims are wrong.
