I recently bought a pair of TP-Link AV2000 2-port Gigabit Passthrough Powerlines. I haven't hooked them up yet (I'm still moving into my new home!)
My system will be as follows (as I understand it): My cable modem will feed to my router. One of my router ports will feed to my computer and one of my ports will feed to one of the TP devices that I'll plug into a convenient wall socket. That will make my home's electric wiring system an Ethernet network. I'll then plug the 2nd TP device into a wall socket in my den so that I can have an ethernet feed to my TV and to my Roku.
If there's anything wrong with my above understanding of what's what, please let me know.
In addition, I thought that I needn't stop there. It seems to me that I could buy a hub or a switch (I don't know which would be better) to split my Ethernet signal before feeding it to one of my devices (the TP device has two output ports). By doing that, I could link both of my laptops to the Ethernet signal via the hub/switch and get off the WiFi grid altogether.
My first question is: is the above possible and, if so, what are the downsides, if any? A degradation of signal, etc.? And, if it's possible, which is better to use, a hub or a switch?
I'm new at all this and my imagination is often off the scale, so I need some cold reality thrown into my face. Thanks.
