I wish to split one of the outlets on my router in two so that I can access the LAN from another room when I take my Laptop there and I would rather not keep unplugging the LAN cables each time I move from room to room I prefer not use WiFi in this instance. If I connect a simple splitter to one of the Routers outlets and then connect each LAN cable to one of the new outlets will I have problems, is it similar to television signals which are halved when a co-axial cable is split?
Also what is the TP-Link TL-SF1005D 5-Port 10/100Mbps Unmanaged Desktop Switch, would it do the same job?
You can't just split a network cable into two which is what I think you are suggesting. It is not like splitting a TV antenna cable (which actually reduces it by much more than half as the impedance matching is upset). Apologies if I am reading it wrongly. If you want to avoid having to connect a cable every time then you have no choice but to use wireless. You could use a homeplug type device but that depends on whether you want to stream HD videos for example. Homeplug and possibly something similar to this click here might be your only solution as the ethernet network cable would be permanently attached to the homeplug. It would require 2 mains sockets to be in use all the time though. Seems a terribly complicated way just to avoid plugging in a network cable on the times you go into the other room. Wired connections are faster, more secure and cheaper.
I'm not sure if you have grasped this. Forgive me if I am wrong but I don't want you to spend money and find it does not work. A cheap splitter will not work on its own. You have to use 2 of them, one at each end. So you will require additional ports on your router. If you have one spare all well and good otherwise you will need an additional switch to create the extra port.
