PiHole on a dedicated RPi 3B+ should be able to serve as DHCP and DNS blocking for a home network, ~40 total connected devices (a few computers, some phones/tablets, and other various internet connected devices).
PiHole FTL has started taking 100% CPU time, and DNS requests sent to PiHole went from mostly working to taking 30+ seconds or timing out completely.
Bypassing PiHole yields good internet speeds with ads. Even SSH into PiHole or pinging pinhole leads to instability and ~75% packet loss. Connecting Pi to physical KBM allows for basic management.
Many attempts made to generate debug log. Either times out (web interface connected to Pi admin console) or get the error ‘There was an error uploading your debug log’ when running on the RPi directly.
