I use it as DNS add-block (pi-hole) and a Plex server. My pi-hole is stopping working from time to time..
I had a similar problem and discovered that the network card on the pi was going to sleep to save power. Since I ssh into my pi, that was hard to figure out, but adding a cron task to ping the router fixed it.
How often did you have to ping and/or where did you find the sleep timeout value?
That's next when its project box accumulates all the parts. I think I'm almost there!
Does the plex server works properly?
I installed it on the RaspberryPi but unfortunately, I never managed to watch a full movie in good conditions.
The Pi wasn't powerful enough to display the media (video file).
