This is my first 2 story networking setup I've come across in my various living situations and need some help. Let me describe my current setup:
I have a 2 floor townhouse with the living room on the first floor. In my living room I have my entertainment center with my TV, PS3, 360, Cable Modem, and Cisco Linksys Wireless Router. I have the PS3 and 360 connected to the router via ethernet cables since they are only about 4 feet from the router and i use both for Netflix/video streaming as well as online gaming (of course). Up until now I have just had a laptop and tablet, the wi-fi downstairs is amazing but upstairs in the bedroom or guest room it's about 2 bars strong which is totally useable for the Laptop and Tab.
Ok, here comes the problem. I am finally building a mid-range gaming rig, something I have always wanted to do and finally have a budget to afford. BUT, the PC will have to be upstairs. I will always prefer and fight for a wired connection for a desktop PC, especially for gaming. As you have seen from my current setup, all of the wires are downstairs. To add to that, I cant run any cables to the upstairs or drill or add anything to the house (renting, not owning).
So the main questions:
Any recommended setups for my situation?
Do I move the Modem and Router upstairs to have the PC wired and put the gaming consoles on wireless?
Do I try powerline (the townhouse was built in the 70s, not certain of the circuit situation)?
Do i get a range extender and just connect the desktop on wifi?
I've used powerline adapters many times in that sort of arrangement and they work fine although not even close to the advertised speed. Get a 200 or 500mbps model and plug one in near your router and the other upstairs near your computer. If you have interference sources on either line, like a room fan, put the interference source on a 6 foot extension cord -- works as well as an interference suppressor.
A powerline adapter is an excellent solution for a single PC. You could also buy a wireless access point in addition to the powerline adapter, and instead of running a cable from the upstairs adapter to you gaming rig, you could run it to the WAP and have stong signal for all your upstairs devices.
