I am constantly rubber banding when I am playing Rocket league (or any other online game) but My ping never spikes. My ping usually sits around 17-20 and when the rubber banding happens it never spikes up. This is why I think its some kind of issue with my pc. I live on a college campus so unfortunately I don't have access to the modem.
Troubleshooting I have tried:
Updating my bios, and all my drivers
Reset my cpu overclock to default
Reinstalled the game
Disabled Dynamic Tick
Messed around with my Wifi adapter settings
Any suggestions would help a
