About two months ago I installed pi-hole in my home network.

Because my router does not allow setting DNS I had to activaty pi-holes built in DHCP server and deactivate my routers DHCP.

Currently I am facing connectivity issues on all my devices: every now and then, the internet connection will just... be gone. All pings time out.  
So far I have not been able to identify the source of my issues. I would like to be able to rule out the pi-hole, though.

So I guess my question is:  
Is it at all possible or likely that pi-hole causes these connectivity-issues or can I pretty much rule that out?

Thanks for any answers,  
Ben F

Only pings to host names or also those to static IP addresses? Like

```auto
ping 8.8.8.8

```

I'll continue assuming the answer is "yes, all of them".

The only thing Pi-hole's DHCP server does is assigning IP configurations to your devices. At some point they expire and the clients will have to renew their leases. If they fail to do so, they may be left floating without proper connectivity to your network. So far to your question: "Is it at all possible". However, running the Pi-hole DHCP server myself for nearly half a decade now, I wouldn't say it is likely. At least not without external unusual circumstances like you shutting down the Pi-hole several hours every day.

You can easily check this if you verify they still have an IP address (depends on your operating systems how you can access this information). You can check if you can still ping the router or other devices in your network (if you haven't done this already).
