Pi-hole randomly disconnecting internet

Background:

  • I'm running Pi-hole off a Raspberry 4 that uses the approved/official power cord and is hardwired into the router.
  • I'm having to run DHCP through Pi-hole as my ISP won't let me assign a static DNS.
  • I have unbound installed and a cron job to reboot the pihole every Saturday morning at 4am. (After I initially set up the cron job in the hopes that it would fix things, I didn't need to reboot for about a week and a half. Until the problem started again.)
  • I updated to the latest version of Pi-hole (v 6.7) last week and there were no issues with the update.
  • I have IPv6 disabled.

Expected Behaviour:

My expectation is that the internet should work regularly and not randomly disconnect.

Actual Behaviour:

Previously, the internet would disconnect on a weekly basis. I have solved and continue to solve this by unplugging the router and the power cord of the Pi, waiting a bit, then plugging the router and Pi power cord back in. This has fixed it.

However, this week, it feels like every couple days (instead of once a week) I'm randomly disconnected. I've tried to ping the router address as well as 8.8.8.8 when the issue is happening: 100% packet loss (not surprising considering the internet is effectively disconnected) and I'm unable to access the Pi-hole admin page as well.

I've also searched this topic and I'm unable to find a fix that can solve what is going on.

Appreciate any help the community can give in advance!

Since I am not a dev, I cannot see your log information but I will offer this word of caution. Just unplugging an RPi without shutting it down cleanly is a surefire way to clobber your SD card, or at least corrupt its file system. This can cause all manner of hard to diagnose things.

That sounds like a Router issue and not a Pi-Hole issue ?!

Even without Internet connectivity (WAN down) you should be able to reach your Router (LAN should stay UP!) :wink:

Yeah I've wondered that as well. I guess my question is: before I setup the RPi and Pi-hole, I never had issues with the router. It wasn't having to be reset every week. This has only happened since I set up Pi-hole.
