Get a small 5 port switch to connect to your R45 wall jack.

Hi, There are several different wiring congfigs for LAN "splitters", are you sure you have the correct ones?

The company I used to work for made them under the name "coolports".

If it is just RJ45 splitters, then that is your problem.

They have to be Cat5e splitters.

However I agree with crazijoe and just pick up a cheap 5 port switch.

I'd go with the switch, you're making this problem harder than it is.

If these "splitters" are what I think, they exploit the redunant pairs in a LAN cable and the term splitter is a bit of a misnomer.

This being the case (and I assume the router is in a "comm" room or similar) then it could be that the link does not have 4pair connectivety and so you are on a hiding to nothing!

Sometime a poor installation might be up to 5, 5e..... spec' on the normal pairs but not up to snuff on all.

I would cold check all the pairs on the link before you buy anything else.

The splitters indeed use the secondary pairs in the CAT5 cable for the second circuit. I've used them here for a long run where I didn't feel like pulling another 100 feet of cable through the attic and basement for my FiOS installation.
