I'm planning to buy a Raspberry Pi Zero W in order to use it as a r/pihole. However this version has just a wireless interface. Since i need a stable connection i want to add an ethernet port. I could do this in few ways:
From the technical point of view which one is more stable and best for DNS traffic?
With the second option could i use just the USB plugged in my Fritzbox
7490 without the ethernet cable, since the USB is already providing
connectivity?
Thanks!
