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 (192.168.12.1) is not responding".
and “Security or Firewall settings might be blocking the connection”
Also I can no longer access any of my networked PCs or access this laptop from any of my PCs.
Can anyone suggest how I could fix this?
Thanks in advance.
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”

Other PCs on my network are OK and can access each other but cannot connect to my VAIO laptop.
Your Vaio laptop must be connected to your T-Mobile gateway first, either by WiFi or ethernet cable, before 192.168.12.1 will respond.
Your T-Mobile gateway’s SSID and network password must be entered correctly on your laptop, before the laptop can successfully connect to the gateway.
If you are running a VPN for work some will allow using split tunnel which will allow the access to local resources such as a printer and still have the secure tunnel to the corporate LAN.
Other PCs on my network are OK and can access each other but cannot connect to my VAIO laptop.

No kidding Tom. It is CONNECTED, I can open dozens of web pages, do e-mails and so on. I do know the SSID and PASSWORD for the gateway, I have been using it long enough. I can connect to the gateway from my desktop PC and another laptop using the SSID and PASSWORD, but NOT from my VAIO. My other machines can communicate with each other but not with the VAIO and vice versa.
A good try but how about another suggestion, please. The failure has nothing to do with SSIDs or passwords. Something on the VAIO is preventing the connection and networking to my other machines. Here's a couple of pics for you to chew on.
I would rule out the Windows Firewall first thing. If you disable the firewall, as a test, then you can see if it is blocking the connection to the gateway. I suggest using "Control Panel" to deal with the firewall. Press the Windows start key, type control panel and then select the firewall. I use Bitdefender's security suite so I avoid the W10 firewall myself. If you have at one point or another in time changed FW settings on the laptop restore the defaults and see if that helps.
If you temporarily disable the firewall to test; open a command window and ping 192.168.12.1 with a continuous ping. i.e. [ping -t 192.168.12.1] If the GW responds enable the FW again. If the ping continues then try to web into the router from the client. Another test is to ping the subnet broadcast address, 192.168.12.255 and then look at the ARP table. Issue the command arp -a and see what the client has learned of the other clients on the network. Determine for sure the IPv4 and IPv6 status of the client with the command ipconfig /all. I run a dual stack IPv4 & IPv6 and I have no issues with the Nokia gateway on MAC OS, Linux or Windows 10 Pro so I suggest to run both in the IP stack. Compare the settings for a working client to the laptop client. See if there are different settings.
If you can't ping the router with the FW up or down this is a curious issue.
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.
Thanks very much for the information, I did PING the gateway and it failed. I have made another discovery today. The problem is broader than just the gateway access, I can no longer access any of my networked machines or access this laptop from any of my Laptops/PCs. I pinged those too and they failed as well. My Dell PC and my Sony Laptop which I could access before I went away can still access each other, but neither of them can access my VAIO SX14 laptop and vice versa.
I have check all of the settings on the SX14 and even compared them to those on the Dell PC, they all look the same. But the SX14 will not connect (Map) to anything else. When I try the only thing that shows up in the mapping browse window is the SX14.
I undid the most recent Windows 10 update, it made no difference. So I reinstalled it.
I also killed my firewall, malware software and my VPN, but to no avail.
I shall try the ipconfig /release and ipconfig /renew later today and report back with my findings.
Here is the result of running ipconfig /all command:
