Cannot access my Gateway at 192.168.12.1
Using my VAIO SX14 Windows 10 Pro Laptop: I cannot access my Gateway at 192.168.12.1. Network trouble shooting says "You computer appears to be correctly configured, but the device or resource (192....
After a lot of investigation, I uninstalled the VPN and I can now access my gateway 192.168.12.xx

My guess is that he plugged a router into the T-Mobile router, as you speculated, and it served the 192.168.12.1 DNS server up on its ethernet segment as the DNS server. No way clients on the second broadcast domain can ever be routed out and back as the T-Mobile router will never know of the ethernet segment on the other side of the other router. In effect he needs to turn that to bridge mode and disable the DHCP server or just shut the old router down. Unless there is a demand for expansion of the wireless to try to cover more area the best solution is to just go with the T-Mobile router. The second router would have the double NAT solution and well that could cause issues as well.
My TMHI Gateway is the router, it is an integral part of a single “box”
The objectives from the commands are to determine what the computer IP information reports. If turning off the firewall allows the pings to pass I would speculate a config issue. The ping of the broadcast address should populate the client's ARP table with the IP addresses of other active clients on the network segment. Looking at the full IP configuration via the command line will provide a full view of the IPv4 and IPv6 information from the client. If you see an IP address on one of the clients that is the same as the laptop then a duplicate IP address would be a problem. I will assume you are using DHCP to obtain an address for the laptop so I would not expect the DHCP server to serve up the same address. You can use the command line to release and renew the IPv4 address. issue the command ipconfig /release y luego, ipconfig/renew. If you want to do the same with IPv6 just add a 6 to the release/renew (i.e. release6 / renew6)
Another thing to consider is the Windows update status. I have seen my Windows clients behave poorly when updates are pushed in and a reboot does not take place to complete the installation. it may not be apparent 100% the status of updates so I would check this as well.
You state, “I can no longer access any of my networked PCs or access this laptop from any of my PCs.” I can see from your screen clips that it is a "private network" so I would not expect a sharing issue but determining the client's full network interface configuration is important. Look at the details of the network connection before resetting the network connection and then again after doing so. If resetting the network connection does not help look at the driver for the NIC and use another client to determine if there is a newer network device driver.
Also check the "Privacy Settings" and determine if there is some setting that if altered on the laptop that other clients do not have. I doubt that it is a privacy setting but checking for what is different/same is always a good data point. If the issue impacts both a wireless and wired ethernet connection my biggest suspicion is the firewall.
