Computer to router ping spikes normal?

Hi so I've been trying to make sure my network at home is nearly perfect lately, I have an issue with power level difference for my cm600 modem but that's another issue I'm currently working on fixing (mostly waiting on a comcast tech to come out).

Anyways lately I've been monitoring my in-house network to make sure everything is running normal and while looking out for any packet loss issues, I've noticed that my connection from my computer to router has odd ping spikes once in a while.

(pingplotter tests) (first hop is what were looking at)

I've replaced all ethernet cables with brand new cat6 ones, router is only a month old, modem is a week old if that, most of the outside coax cables have been replaced minus one (soon to be replaced when comcast tech comes out). I've made sure our router firmware is up to date, made sure network adapter drivers are up to date, Tried my brothers computer (which had a 25ms spike but when I checked my computer it didn't have one and vice versa, if i had a spike it wasn't showing on his either).

It could be possible there's services in the background that might be the cause of some of these spikes? But I wouldn't have any idea how to pin point which services running are doing it and nothing crazy is running like virus scans, updates/downloads, etc. that would for sure be a sign of taking up connection.

About the router it's self.. it's a netgear wndr4500v3 (n900 450+450mbps), we have 3 computers and 1 smart tv hardwired to our router, 4 phones and 1 tablet on the wifi. The only settings I've changed on the router since It's been installed has been turning off QOS settings and setting up a password for our wifi 2.4ghz channel and 5ghz channels.

Our main computers are meant for gaming (home built) our ethernet ports are part of our motherboards. I'm ruling out if any dust on the motherboard or in/around the port is a cause later today when I go out and get canned air. Aside from that is there anything else that would pin point the causes?

SIDE NOTE: I assume when testing the connection between computer to router, that anything beyond that doesn't affect the routers ping when just testing this? My thought behind this is that our modem's power levels has a odd swing on a few channels which could make the signals not as stable? But again.. I figure that wouldn't have anything to do with pinging just the computer to the router. My other guess is that the router's settings has ping protection of some sort which in turn would be the cause of these odd looking spikes when I try testing it and perhaps it's fine so long as I'm not testing it?

If there's any info needed aside from what I've posted I'm willing to post the modem signals and or router settings to pin point if there's a issue at hand.
 
if you have windows 10, there are apps that running in the background such as the weather, calendar, get office, insider hub, etc... you can disabled them by go into settings > Privacy > Background apps and turn them off.

Did you use Wireshark?
 


Forgot to mention that but this is with all computers running windows 7 and I haven't used wireshark, is that something I can run on win 7?
 
update.. for the last two days my connection from computer to router ping test was showing max 5-6ms, now tonight when I tried another ping test it's max spike was 16-18ms.

What wasn't being used in the two days was our smart tv in the living room that is connected by ethernet, then tonight my parents came back from a trip and watched netflix during my test that showed 16-18ms.. Wondering if by the sound of things, if this could be the tv being in use causing random spikes on our router? My other guess would be one of our phone devices connected with wifi is some how causing the router to spike for my tests?

I've already cleaned out my computer and around/in the ethernet port.
