Port Splitter

I have 4 ports on my router, and I need six. Rather than getting a switch/hub, I’d like to plug two non critical items into one port on the router.

I’ve seen many RJ45 splitters, but most use the redundant wires to send two connections over one cable.

What im looking for is single RJ45 out of router, to two RJ45 connections. Im not worried about bandwidth.

Any ideas?

Unfortunately it doesn’t work that way with an Ethernet port. It’s a one to one device connection. So to get more ports, you would need to cascade another switch or hub from one of the ports on your router.

Would this work?

Unlikely ... it is either one or teh other.

You can get a very small 5 fport switch such as a UniFi FLex Mini for £20

I’m ideally looking for something unpowered, as I’m ditching an 8 port switch, and it’s just the last two devices I’m left with only one port on the router

Does your router have PoE?

The hub or switch is going need power - either from a wall socket or via Power over Ethernet as noted by @mhc

5-port and 8-port passive/unmanaged switches are very cheap these days. I’d recommend one over a scenario where you would need several of the devices you linked from Amazon.

That seems unlikely, the only ones I've come across that do are niche ones from Ubiquiti and Mikrotik.

There are a number of 5 port switches that are powered by 5V. If the router has a USB port, and a lot do there is a possibility that it will provide enough power to power a switch. You might however need to make/purchase a suitable lead.

The power requirements are *very* lower for Ethernet these days. For example if you would be happy with 100Mbps (and that's all a lot of routers have) then you are looking at under 2W max power consumption. Even a 1 Gbps you are under 1W a port. These are max power consumption figures in a domestic environment with a "Green Ethernet" you will see lower power consumption mostly because the switch will be detecting the cable length which will be considerably less than the 100m maximum and back the power off considerably.

Frankly consumer routers need more ethernet ports than the four they typically come with. I saw the results of a survey a few years back that suggested that more ports was one of the top features people would like. But hey ISP's penny pinch like there is no tomorrow.

I guess a USB powered small hub would do the trick.
