Internet connection drops every 10 seconds on Macbook Pro (M1 Pro)

So, a recent issue with my Macbook Pro w/ M1 Pro running macOS Ventura beta is that it keeps dropping its internet connection *exactly* every 10 seconds. Regardless of whether I'm using ethernet, work or home wi-fi, or even my cellphone's hotspot. For example, results of ping:

google.com

I've tried: - turning wifi off and on - restarting - renewing DHCP lease - deleting wifi or ethernet service in Settings -> Network and re-adding - using different DNS servers like 1.1.1.1 instead of the default The fact that it happens on either wifi or ethernet, whether at work or at home suggests it isn't a router problem. Any ideas? **Edit 1:** Per Allan’s suggestion in the comments, I restarted into Recovery mode and used the Terminal there to ping google again, and there are no drops every 10 seconds. But logging back into non-Recovery mode, the problem remains ;_;
