Ok serious question I just picked up this Ethernet splitter and I was hoping to split pre router in an effort to bypass the router and bump speeds slightly. Is that actually going to work or am I just dreaming?
Your router uses NAT (network address translation) to share a single IP, allocated to your internet connection, among many clients, such as your gaming PC.
Those Ethernet splitters also don't let you pass the input signal to more than one output at a time - you couldn't have the router and the PC on at the same time.
However, what do you mean by "bump speeds by bypassing router"? If you see any improvement what so ever it will be only on your local network, there is no way to gain internet speeds like that
There is ONE IP address available from your ISP to your home, so even if that splitter physically "shares" the electric signal, only ever your router OR whatever is on the other end of that splitter will get it and with it a working data connection to the ISP (and that's assuming it even works). Further whichever gets ot os sorta random and it won't really jump between one and the other at need - you're sharing the physical line but not the actual data connection.
Frankly, if your router is somehow making the connection slower, get a better router as well as the correct ethernet cables for reaching higher speeds (i.e. gigabit ethernet won't run on cheap Cat 5 cables).
It's not slow by any means but I had to move my modem and router further away to reach all parts of my house better. So I was laying the Ethernet cable and as I was plugging it into the router I just thought maybe that would give it just that little tiny boost. But I just won't do it now. Thanks for that
