Windows 10: Multihomed Network?

Not sure if that is the correct termination, but maybe. I apologize in advance if this is lengthy,
,
My issue: I set up an office for a friend many years ago, which had the basics... Five Workstations, One Server, One Router, and things were dandy for years. Printers were shared, via whichever pc is was plugged into, and there were a few common shares for docs, etc. The server managed the workgroup, as well as contain the company business software. The OS was Win7 and Win7 Server. The network router at the time was not wireless, but it all wired connections came from the router, thru the firewall into a Lansys Switch. From there, all connections were wired from the switch.

Over time, a few more people started working there, laptops were brought in, and somewhere a wireless router was installed. I'm not certain how they managed to do this, but problems started occuring, and they hired some local to put a band-aid on it, as long as they can connect and do business with the company software.

My friend informed me the vendor of the company software advised him all workstations needed to be up to Win10, so he asked me for help. My nightmare began when I walked into the office and discovered everything I set up had changed, and there was no documentation taken at all of what changed, so I'm blind at the moment.

The one major change I see is the Server was upgraded, new machine with 2tb HD and Windows 10. However, it is no longer Server Software, it is regular Win10 Pro, acting as the Server for the company software.
The other major change is the Switch is no longer in the network, either the vendor or Spectrum told them to remove it. All wired connections are straight to the router, or moved to the wireless.

So, my question(s) are these:
( 1) How did they manage to add a wireless router without it conflicting with the gateway? The subnets are not the same obviously, so I cannot see the wired computers from the wireless computers.
(2) All computers can connect to the company software, on the new Win10 NonServer workstation, but they cannot see each other (wired vs wired), is this normal?
(3) How would I resolve this and normalize the network without the business coming to a halt?

My first thought is this: Go back to my original design and re-configure as follows:

(1) Starting with the router, remove the wired connections, and also the wireless router if in fact it is connected there.
(2) Connect the switch to the router with firewall in between.
(3) Replace wireless router with a WAP and connect to the switch.
(4) Connect all wired to the switch.

This scenario seems proper to me with one exception.. The business software, which is no longer on an an actual server, runs on a regular PC acting as a server. Do I run the risk of compromising it by this configuration?

Any meaningful suggestions would be appreciated !!! Thanks

Did our Epson printer get hacked?

Another question, is this on a home network or a work network? The steps @eidairaman1 listed are always a good first step. If this is on a work network you manage, I'd be much more concerned than the home one. It is possible someone is screwing with you, but malware could also be the culprit.
