Hello, first post here. I'm planning on routing Ethernet cables so as to have a better network connection then wireless because my router is located all the way on the other side of the house. Now I have temporary set up where a cat5 is plugged into a, what I would call, a router extension? Our internet and television is bundled so where we would plug in a television reciever I plugged the cat5 and ran it through my halls to my ps4. I mainly want a wired connection because my ps4 suffers bad connection from where I am wirelessly. Now I have 2 questions. I'm planning on wiring a catX wire through my ceiling to either the router or the router extension(please tell me the true name if you are familiar with what I'm talking about it) I want your opinion. Should I plug into my router which has plenty of cat5 outlets to supply my pc AND ps4, or plug my pc and ps4 into the router extension, which only has one cat5 plug, into a splliter and run that way. Also, can someone explain cat5, cat5e, cat6, and cat7? :/ thanks everyone
