Ethernet vs Wifi and Confusion

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.
