For the past 3 months, my PC has been having these constant ping spikes every 15-20 seconds. It exists for any internet connection (gaming, browsing, etc) and has been very annoying. I use a wireless connection and I have tested the router's connection on my other devices and they all don't have this problem, so I suspect it must be something wrong with the motherboard WiFi. I have made numerous attempts to try to resolve this problem, but with no avail. I would deeply appreciate any advice on how to resolve this.
