Wow! That worked. Changed the metrics to 1 (LAN) and 100 (Wireless),
then pulled the internet on the lan and still have internet access and
can still print. Excellent job, Jamie!

Try changing the interface metric like I said below. By default
Windows will prefer a wired connection over a wireless one. I don't
know if that will work or not though but it's worth a shot. It's worth
a shot though I don't know if it will work.

Well, I knew this was going to be a learning experience. I took
Thane's advice and changed my DHCP network to 192.168.2.1. Did the
stupid and forgot to change the subnet mask. Reset the router,
changed both address and subnet mask, then found out that I had to
run the Windows troubleshooter to reset the network connection for it
to work. Reinstalled wireless, then pulled the internet on my
router. No go. While I still had access to my network, there was no
internet and Windows was complaining that there were two active
networks and to unplug everything. So, any advice here? I'd like to
retain the router to make things simpler. I'm still trying to find
the right search words to get what I need on the net.

The behaviour you're seeing is likely because there's a router
handling DHCP on the wired network, and that DHCP packet also has a
default gateway. When you plug in the cable, the computer receives a
DHCP response from the router saying that it's a valid connection,
and most of the time Windows prefers physical cables to wireless.
It may work with the router is still plugged into the LAN network
(without the Internet connection plugged in) if you go into adapter
settings on the computer and set the metric of the wireless NIC to
1, and the wired NIC to 100. (Settings -> Network & Internet ->
Network and Sharing Centre -> Change adapter settings, right click
on network connection -> Properties -> IPV4 settings -> Advanced ->
metric text box). The problem with leaving the router in play is it
will do DNS also, and that may confuse the computer or servers if
they don't get responses or gets bad responses back from the router.
To get rid of the router (or if the above doesn't work) you'll need
to follow through a few things here to make this work. This sounds
like one of the rare cases to use static IP addresses on the wired
network - make sure like Thane said that the two networks have
separate IP ranges, and there's no default gateway set for the wired
LAN devices. I would statically set the IP addresses on the devices
on the wired network and add if you use names for them then add them
to your hosts file.
You should end up with something like following structure:
* Wireless - 192.168.1.0/24
o handled by DHCP - actual IP range doesn't matter so long as it's
different then the wired
* LAN - 10.0.0.0/24
o 10.0.0.X (where X is unique for each device)
o netmask 255.255.255.0
o no gateway
o no DNS
In the %WINDIR%\system32\drivers\etc\hosts file on your machine add
a line like this for each server (the printer software will likely
figure it out once the printer is assigned a static IP address,
though it may take a reinstall). You may have to turn off the
Windows Firewall for the connection or set it to Private if Windows
prompts to ensure you have full connectivity to devices on the LAN.
10.0.0.X server1name
10.0.0.Y server2name
I do something like this when I want VMs in a separated network
(with no Internet access) for testing. The biggest difference is
that I do use DHCP on the split network, but there's no gateway
defined so it works without having to configure each host. That
means having a DHCP server and the knowledge to configure it though.

We're dealing with Win10 here. We are trying to get rid of an
extra cable internet connection at my house. The downstairs
currently has it's own internet with a wired network that includes
two servers and a printer. What I need to do is keep the wired
network without internet and access the internet wirelessly and
still be able to access the servers and the printer. Can I get
some guidelines on how to get this done? I've got a good wireless
adapter on my desktop now and it works, but when I plug in the
network cable, internet access goes back to the wired network.
Still searching the web for something coherent about this, but with
this group, someone has done it at sometime, right?
Thanks...Steve
