Dell G3 3590 Ping Spike Issues

Hello

Recently I have been having issues with my Dell G3 3590 laptop. When wirelessly gaming online, I am experiencing consistent ping spikes to the thousands every 10 - 30 seconds (no spikes with a wired connection). These spikes only occur when gaming and happen in all multiplayer games. That is, when I am playing a game that does not require internet access there are no ping spikes. I have also tried playing a game offline while running Netflix at the same time and did not experience any internet issues. The problem seems to only occur when gaming online. I have tested other devices on the same network and they don't experience the spikes. 

One interesting thing I found was that the spikes actually go away after I restart my computer, but eventually return after around 30 minutes. This made me believe an application might be causing the problem, but after performing a clean boot disallowing any applications and unnecessary processes from running the spikes were still there. I also carefully watched the task manager and resource monitor and was unable to identify any specific application causing the spikes. 

The following is a list of some of the things I have tried to fix this problem:

- Reinstalled all drivers for the computer (all drivers are now up to date)

- Downgraded my BIOS (now up to date after this didn't fix the problem)

- Both downgraded and updated my wireless adapter 

- Updated to the most current version of windows 

- Disabled windows the ability to download updates for other computers and temporarily halted windows updates 

- Ran a full hardware scan through support assist and ran all windows internet troubleshooters

At this point I am at a total loss. Nothing I have done so far has been able to fix the issue. My best guess would be that there is some hardware issue with my computer. I would appreciate any help.
