Ethernet vs Wifi and Confusion

  1. Okay so before I begin I'd like to say I am relatively new to computing and I'm not the most knowledgeable.

    Let me explain my setup:
    I have a HP Envy SleekBook Laptop which is connected to my BT Wifi through a NetGear HomePlug which should give me wired internet.

    I cannot move the router which is that the other side of the house and I decided to test me internet speed on speedtest.net I got nearly exactly the same values when using the ethernet cable and when connecting to the internet.

    I often have ping spikes and lag in CS:GO.

    That is my main issue and my secondary discussion is if this is a good setup : (I have ordered this stuff)

    Just reading the title, Ethernet is better because its wired. Wifi goes thru the air & can be blocked by too many walls, cabinets,floors & such. As for the rest of your questions, I don't know. :)

    Let's start with this;
    Code:
    ISP==modem/router --- wired --- Lan attached PC(a)
                |
                + - - - wifi - - connected device PC(b)
    
    and ask what are the perceived bandwidths seen by A & B?

    System A will be limited by the lessor of
    • the ISP connection
    • the speed of the NIC card in A
    • the precise TCP settings in A
    System B is just like A but gets further limited by the WiFi connection (a,b,n,g,ac)

    So it is entirely possible that the bandwidth of A is exactly that of B when the limitations are created either at the modem/router or the ISP connection itself.
