Connection drops randomly throughout day.

I have been having this issue for about a month, now.  Throughout the day, the best way I can describe it is that the internet has small hiccups during the day where there will be no signal to the internet from any device (wired connection directly from modem and Wi-Fi).

It really comes to pass whenever I try playing games over the internet.  My latency will spike up in the game, then when I run a speedtest - I will notice that my download speed has halved and my upload speed is basically non-existent causing a disconnection over and over again.  Most of the time the speeds are pretty steady, I get about 940 mb/s over wired devices and 350-400 mb/s over Wi-Fi devices, but whenever one of these hiccups happens, wired connections go down to 250-300 mb/s and Wi-Fi hits somewhere around 90 mb/s download and around 0.14-2 mb/s upload.

The modem was switched to a new gateway when we got the notice that the service increased from 1 gb to 1.2  so it's a brand new gateway the cable connection has handled the gigabit connection for over a year and a half and nothing has changed connection wise.  Still using the exact same computers as before.  I have done all the normal stuff as far as checking cable connection, splitter that is installed goes directly from the cable into the house into the splitter to the coax jack that the gateway is connected to.  All ethernet cables are 5e.  I'm sort of stuck here, because this has been going on for awhile and it's really hard to predict when it may happen.

I'm not sure how to get the normal information that is requested with power signals from the modem itself, but I have tried to get what I can.
