Every month or so all my devices lose internet and the only way to connect them all back is to disconnect them from the DNS server that Pihole is running.

I set my Pihole to have a static IP but for some reason after around a month or maybe longer, it just fails. This has happened 4 times over the last while and the only fix is to essentially uninstall everything on my Pihole, disable it, and then reconfigure it from scratch again.

I’m not sure what’s going on so any help would be appreciated.

Give an alternative a go, see if you have better luck. There's adguard home, blocky, and Technitium DNS for you to consider.

Alternatively, the window trick should work.

I had reliability issues with PiHole and moved to AdGuardHome a couple of years ago. It has never, ever crashed and the updates takes a couple of seconds. It rocks.

I haven't done any research on pi-hole (I use firewalla) but is a raspberry Pi even powerful enough to support a small home network?

What kind of CPU/RAM usage for a your unit normally have?

Ya from my research raspberry pi is powerful enough to act as a DNS server for a home. I probs wouldn’t put a 4k plex library on it but it should do the job.

In my case however I’m not running a raspberry pi. I have installed PiOS into Windows using WSL (like a lunatic) in an effort to not reformat my whole server computer and install something more practical (like Ubuntu server).

Clue in name.

I give my pihole container about 1GB of RAM and one core and it's good to go (two cores helps with maintenance tasks though.) An entire RPi just to run pihole is such overkill.

It's not that much of a strain since it only handles DNS traffic.

When you go to e.g. programming.dev, you computer needs to know the actual IP and not just domain name so it asks a DNS server and recieves an answer like 172.67.137.159 for example. The pihole will just route the traffic to a real DNS server if it's a normal website or give a unkown ip kind of answer if it's a blacklisted domain. Actually transmitting the website which is the bulk of trafic is handled without the piholes involvement.

How do you set the static IP for the pi? From your router's DHCP server, or from pi's network configuration?
