Hi,

In my office I have a single RJ45 port (IO Jack) and 2 users. I want to provide LAN connection to both users computer. I purchased a hardware RJ45 splitter and connected the RJ45 patch cord from main IO Jack to splitter and connected the other 2 ends of splitter to the 2 computers. But both computers LAN connection was going On/Off.

Is there an alternate using which I can give both computers LAN connection using a single RJ45 IO port?

I don't want to use a second network card option as users are having Laptop with them.

Thanks for your support.

I've never used an ethernet splitter, but logic suggests you might need to use a splitter on both ends (you probably also need to split the other end in the network closet so it connects to two different ports on your switch).

Cheers,

Nooo - Ethernet spitter - such a bad idea. They were invented on ebay for user feedback only!
The computers cannot negotiate a connection like that. BUT if you insist - like mentioned, they work by using one at both ends of the cable. But seriously, if you value any type of network data transfer - dont use them.

Why dont you just buy an inexpensive switch to stick in your office?

Something like that would do just fine. And you also have room to expand to more PCs/more phones

Without running a new cable / new wall socket - that is the only way you can do it.
Unless you want to get into un-necessary complex routing between computers (using 2 nics) - that you didnt want to get in to.

You are right Naykam, I had to revert back to small switch only. Splitter is not a practical solution and does not work in case of POE IP Phone.
