Here's a review from that Amazon link: 'Basically a CAT5 splitter should take Pins 1-8 input and deliver pins 1236 to pins 1236 on the left socket, and pins 4578 to pins 1236 on the right socket. You would use two of these at each end of a single cable to break it out into two sockets at each end thereby enabling two computers/devices to work.at the same time.

This device does NOT do that.It is a parallel all-pins-to-all-pins and so two devices connected at the same time will fight with each other and both ultimately lose.' I would just buy a router. RJ45 Cat 5 LAN Ethernet Splitter Connector AdapterMy 'splitter' is connected directly to my modem with a cat5 cable which is then 'split' to two devicesOh my, that will not work.Not even a little bit.1. Your modem will serve up one and only one IP address, to the first device it sees.2.

You need a router.3. That 'splitter' would not work, even behind a regular router. You'd need an actual switch.Modem-router-devices.The modem talks to the router. The router creates multiple internal IP addresses, and talks to multiple devices.

The poor-man ethernet switch?Knowing this is not a standard ethernet thing, I was curious of what people use this gadget for. The first positive review says 'use one machine at a time.' The second review says 'use both machines simultaneously fine but he specifically gives out another link (Amazon has the bad habit of grouping similar products into one block). The third review says 'don't buy this' and explains why.OK Matt, am going to repeat what others have already said and tell your using this gadget to gain an additional ethernet port, is non-standard, you are on your own. The proper way to do this is to buy a switch.

A gigabit variety usd$20-40. If 100 mbit is good enough you can get one for usd$10. You can share the internet using a switch that way, I've done it before with a switch tied directly to the modem after my router burned out and I waited for a new one to be delivered. I had two desktops and a laptop wired with Ethernet into the other three ports of the switch.And what device was serving up the internal IP addresses?A standard switch does not have the brains for that.I finagled the laptop into controlling everything. It was on the second port of the switch, so it was the first thing seen by the modem.

The laptop was also using its WiFi adapter to share the internet to other WiFi devices. Performance wasn't great, but it did the trick for a few days.

I've just tried using two different ethernet switches on my network to replace an 8-port Netgear gigabit ethernet switch, which works fine, but doesn't have enough ports for what I need. Computers are connected to a TP-Link TD-8840T router via a switch. They use DHCP for IP address assignment.One switch is a TigerSwitch 6924M, which I'd expect to be difficult to set up, since it is second hand and has an advanced configuration menu, which I can't access without a serial port. However, the second switch that I tried is a new TP-Link TL-SF024, which doesn't appear to have any configuration options, so that can't be the problem.When I say 'not working,' I mean that although they display that they are connected to a network, they cannot access the internet. For example commands like 'ping -c10 google.co.uk' come up with 100% packet loss.What could be causing the problem and how do I fix it? Start with basic network troubleshooting:.

Are all cables connected properly and show link status up?. Did the computer receive an IP address from the DHCP server? ( ipconfig /all). Can the computer ping other computers on the same switch by IP address?.

Can the computer ping the router by IP address?. Can the computer ping the IP address 8.8.8.8?. Does nslookup www.google.com return a result?. Does nslookup www.google.com NAMESERVERIPADDRESS against each nameserver shown by ipconfig /all return a result?.

Do problems persist after you deleted the DNS cache? ( ipconfig /flushdns).
