Consistent internet and DHCP.
This is a bit tricky as I’m not certain what is going on. In short, the pihole works for a few hours then stops providing internet. Sometimes, after anything from a few minutes to a few hours, it will start working again, as if nothing had gone wrong.
When it is not working a device generally cannot get an IP address (and therefore no internet). If you have a connection already it comes up with internet pages not available. If I check the pi zero it generally starts working again (but not always). I ran the debug when there was no internet connection but it seems to have come back online whilst the log was running.
I originally thought it was a power issue but now have a 2A plug connected; it seemed to work for about 24 hours then had the same issue. I have also turned off power management on WiFi.
