Windows 10: ping spikes after getting a new computer

I bought a new computer recently, and whenever i play games or anything the ping spikes really hard upto about 2k once in like 5 minutes at a time. This never happened in my old computer, or any other devices that use the same wifi at my house.

Ping Spikes

Recently, I have discovered that I am receiving ping spikes from 200-1000 every 10 seconds or so when playing games, causing me to rubberband. However, I usually receive around 20ms in between ping spike intervals. I am using an ethernet cable that is connected
'Wi-fi Booster', which is connected to my router downstairs. I have tried multiple solutions in an attempt to fix this issue such as:

• Checking if my network adapters are outdated
• Troubleshooting my network adapters
• Changing my default DNS server to 1.1.1.1 (gives lower ping than 8.8.8.8)
• Disabling the feature where my PC would usually download updates from other computers
• Disabling OneDrive sync in Policy Group Editor

This is what it typically looks like, however it gets somewhat worse over time:

random ping spikes

i get lots of random ping spikes. they dont happen all the time but maybe once evry 2 days and last hours. when i type ping (my ip) -t in cmd it says "request timed out" every time i spike. none of my other devices seem to experience this issue and i even
got a new antenna and its still there. it might be my router but i dont think so. what should i do?

 

Random ping spikes in games

System:

Mobo: Gigabtye GA-A320M-S2H

RAM: 2xDDR4 8GB

CPU: AMD Ryzen 7 1800X

Storage: 1 HDD and 1 SSD (Windows is on SSD)

GPU: Nvidia GTX 1070

OS: Windows 10

Problem

While playing online games, my ping will randomly
spike up. In this time, my computer is effectively offline as I can't do anything online (use websites, discord calls etc). In games with built-in ping counters, it commonly reads 10,000 or more ping. After about 10 seconds, the ping will return to normal.
The ping spikes get less common the longer my computer is on to the point they barely happen. They only start if I play an online game. I have been unable to find a fix that works for the current version of Windows 10.
