2way Cat5 splitter? - Page 4

post #31 of 41
I really don't know. The lights were going on and off for a few minutes. I just pulled it out of the bottom of my bag again to test it out. It looks like you can't have link light on both devices at the same time as you thought.

I am surprised they both don't stay online since this is a layer 1 splitter with no switching device in it at all, and use CSMA/CD.

No one should put a hub on their network in this day and age. Hubs broadcast all network traffic to all ports continuously, thus degrading network performance. Not even sure why they make them anymore, they are utterly pointless since switches were released.

Actually if its Cat5 on a 100MB network only 4 wires are used, you can run 2 network ports on 1 cat 5 cable but it must be split on both ends of the cable. Also it may cause slower speeds if both are in use at the same time.

Heres a guide showing you how to do it.

A switch is the cheaper and better performing route but this work in as pinch

Too much incorrect information in this thread...

So my recontamination is to unplug the main line coming into your room from the pc and put the switch in its place with 2 new cables to your devices.

This is similar to the one i use to add more devices to my router > http://www.newegg.com/Product/Product.aspx?Item=N82E16833127085

And why were your devices so excited in the first place to where they needed to "calm down"?

To the aboves:
Not Entirely correct.
It is correct that you can't SPLIT one connection into two connection, You can share one RJ45 cable drop for two devices.

For everyone who doesn't know RJ45 only actively uses 4 of the lines in the cable.

To answer the OP's question YES you can share one RJ45 line with two devices, but you need a PAIR of these: [ame="http://www.amazon.com/Network-Line-Pair-Splitter-Single-Unit/dp/B000BSLXDE"]Amazon.com: Network Line Pair-Splitter, 10/100, Single Unit: Electronics[/ame]

you need one on each end. the second connection uses the unused pairs in the cable.

hubs have their own advantages, although it should be rare anyone should use them.

take it from a CCNP, the best way for you to do this would be to put a switch on your end.

Don't really know who you were referring to in not being correct, but I am correct in saying he cannot use one of those splitters on two devices at the same time without causing constant IP conflicts.

Nice to see some other certified users on here though. I have an MCSA (XP Pro,70-270 Exam), Network+, A+, and a bachelor's in IT networking.

Think about it. If you 'split' an Ethernet cable how would traffic know how to get to the host it was destined for?

How do you think a hub works? Of course hubs suck it won't be full duplex (have to have a CD per port) but of course you don't have to use a switch.

I'm getting a headache reading this thread... this noob again has the only reply I've read thats correct.

1. Right on!
2. Wrong. A single collision domain sucks, a CD per port is exactly what you want.

The implication was that depending on how many devices he plugs into this hub will be in the same collision domain, which will severely affect performance.

Thanks for the condescending attitude, though.

The real answers to the OP:
Cheap 10/100 switch - http://3btech.net/giwi10et5sww.html
The ultimate stable, small, cheap 10/100/1000 switch that doesn't lock up: http://www.newegg.com/Product/Product.aspx?Item=N82E16833127325

You don't really want to use a splitter as neXt and feXt will be increased, any cable certifier will demonstrate that.

Back in the day Radioshack sold a 3-port ethernet hub that was tiny and would do what you want, but I haven't seen one in forever. You should buy a switch anyway.
