Is it possible to run a twisted-pair cable coming out of a router to two computers through a regular router?

Question

Network administration

There is a large warehouse. There is a wifi router in one corner, it is not enough for the whole warehouse, they do not want to buy a new one. In the other corner of the warehouse there are two computers, one of them is connected by a twisted pair cable from this router, the second one needs to be connected. Pulling another wire through the entire warehouse is somehow not according to Feng Shui, I thought to put a splitter (I googled this one - dlink.ru/ru/products/1/1346.html ).
I remembered that there is an unnecessary old router - can it be used instead of a switch?

Answer 1

Yes, you can use it, the main thing is to turn off DHCP in it. In general, any most stupid switch will suit you.

Answer 2

You can do it even less financially if there is another free port in the router.
There are 8 wires in the cable. We divide the cable on both sides into 2 groups of 4 cores (pairs at different ends must be the same. For example:
White-orange / orange and white-blue / blue
White-green / green and white-brown / brown
Next, take 4 RJ45 connectors / 8P8C and each connector is crimped with wires of one of the groups
Example:
on both sides Total cable 1 - connections - 2. Just keep in mind that you will get a speed of no more than 100 Mbps.

Answer 3

If you are completely lazy, or there is no budget as such, there is a chic crutch! It is possible to separate twisted pair cable into 2 ports. sovetclub.ru/tim/013a69ce856bd004180994eee52ab2b5.jpg like this
