USB-Ethernet for Pi Zero W

I just installed a pihole (and a leafnode server) on a Pi Zero W I just
got. The Zero of course has only Wifi, but I was thinking if for network
stability it might not be better to just use a USB to Ethernet converter
to connect it directly to the router.
Does that make sense? I mostly am thinking it might be more stable than
having my local network DNS run over Wifi.

I wouldn't want to run anything that is critical to the whole network
over wifi.

Id be tempted to substitute a Pi4 B or similar By the time you have
added all the extra hardware to the Zero....

Part of why I want to do it with the Zero is to make it as low spec and
low cost as possible. Of course now I have checked for USB-to-ethernet
connectors, and it turns out micro usb ones are 5 times as expensive as
normal ones.

Don't see why not, prevents you from being affected by wifi interference.

One thought though, if you want an Ethernet Pi it could be worth upgrading
to a fullsize Pi with Ethernet included. The cost of a used Pi 1/2/3 might
be in the same ballpark as buying a USB ethernet adapter: a 2 or 3 would
give you better performance and you get spare USB ports where the ethernet
would block the Zero's single USB (and you need an OTG cable for the Zero on
top of the ethernet dongle).

A counterpoint though is that the Pis before the 3+ only have 100Mbit
ethernet, whereas a gigabit USB dongle would get you about 300Mbit. I'm not
sure what bandwidth you get out of the Zero W wifi, but perhaps more than
100Mbit. So it depends if you're going to be bandwidth limited or not.

That was sort of my point...

ah, found one for under 10 bucks, that should be ok. Will try to use
that one.

Ah but that's assuming that the Pi Zeros are quick enough to run
the USB network interface at the maximum possible speed.
Unfortunately benchmarks show that's not the case. Here they only
get 56Mbits/s to 111Mbits/s on a RPi Zero W using a USB Ethernet
adapter:

The built-in WiFi is even worse, 38.8Mbits/s max., and they also
say that its performance depends on the orientation of the board.

In any case, in this case I want it for DNS resolution and some nntp
feeds. It even has more or less acceptable speeds on wifi
(microseconds), I just want a more stable connection. I don't think that
should make much of a difference.

I think it connects a bit faster than that, but for sure if throughput
is your destination, a Pi zero isn't where you start.

My second one is doing a sterling service and has saved me way more
than it costs by managing my central heating with some smarts.

My first runs a hifi system in one room, connecting to my media server
or the internet to play music.

So much easier than sticking vinyl on the turntable or a CD in the player..

Used to do that over a 9600kbps modem back in the day
Certainly fine on 10Mbps Ethernet

Nothing beats the stability of a wired connection.

I was just realizing that both my Pis have bluetooth, and that I could
actually do something with that. Unfortunately so far I haven't been
able to discover the bluetooth speaker I have with the Pi. I guess I
have to work on that.

Amazon seems to charge about the same for both. I found plenty of options
for MicroUSB Ethernet adapters in the $10-$15 range:

^^^^^^^^
That should be 9600 bps (9.6 kbps)

Yeah, I have it running now. Seems to be fine.
