Most modern routers do not have a WPS button because WPS is insecure. There are ways to still use the LCS wifi and to get the LCS wifi onto your home network.
You can use the LCS wifi in Access Point mode. If you use the LCS wifi in Access Point mode, when you want to do trains, you connect your device to the LCS wifi network instead of your home network.
If you have an old router with a WPS button: Turn off your current wifi. Set up the old router with the same SSID and password you are using for your network. Press the WPS button and join the LCS wifi. Turn off the old router. Turn on your new router. As long as you use the same SSID and password on the old router and the new router, the LCS wifi should now join the new router without any further intervention. I have kept an old router around for just this purpose and used it successfully a couple of times.
You can buy a cheap wifi extender with a WPS button. These usually come with decent software for joining the extender to your home network. Then you just push the WPS button on the extender and VIOLA! If you use the same SSID and password on the extender as you do for your main network, this works the same as the trick above and you do not even need to keep the extender plugged in once you have joined the LCS wifi to your network. If the extender sets up its own separate SSID, you will need to keep the extender plugged in.
The LCS WiFi Monitor LE software mentioned above was designed for Windows 95 but others have reported to work in Windows 10. I have not tried it in Windows 10 myself.
