Network Bridge connection on Windows 10

I have 2 internet connections. Sometimes one is gone down and I have to manually switch to another connection. Apparently, if I bridge the connections in the windows network connection setting it should automatically switch to the other internet connection when one is down. i have tried that, I have successfully established a bridge, but when the ethernet one goes down it does not continue to work on my wifi isp. is there a step I am missing?
Thanks

That is not what bridging does in Windows.

Suppose your desktop has both an Ethernet adapter and a WiFi adapter. It uses the Ethernet connection for connection to the Internet. If you bridge the Ethernet and WiFi adapter, you can allow other systems using WiFi to connect to your Desktop via WiFi and then bridge them to the Ethernet network to get access to systems on the Ethernet segment and to the Internet.

However, to accomplish what you want, do this:

Open Control Panel > Network and Sharing Center > Change Adapter Settings > Select your Ethernet Adapter by right-clicking it and choosing properties.

On the Networking tab select Internet Protocol Version 4 (TCP/IPv4) and then click on Properties. Goto the Alternate Configuration tab. Select User configured and configure your IP address settings.

Here is some info regarding the Alternate IP Address Configuration:

How To - What Does the Alternate IP Address Configuration Do? | Tom's Hardware Forum

Update: I thought about this a little bit more and there may be more that needs to be done to make this work.

The problem is that if you follow the steps I described above, that solution would work and cause your system to use the alternate configuration ONLY if your system is not getting addressing information from DHCP on your primary network. In other words, just the Internet connection going down by itself may not be enough to make it use the alternate configuration. So long as your system is getting IP addressing info handed to it from the primary network, it will use that addressing info.

So, I have a question now: When you switch to the other Internet connection, how do you do this? The issue here is that we need to make sure that you are not still getting address information from the first router or your computer will continue to use that primary addressing info.

I got to most of the time disable the ethernet adapter. thanks

Did some more thinking about this...

Pretty much every setting for your network configuration can be set using the "netsh" command line. You could create two separate batch files. One would run all the commands needed to configure for access to ISP #1, the other to config for the alternate ISP.

This timing is interesting: It just so happens that later today I have a second internet provider being hooked up to the house so I may actually experiment with this a bit over the next few days.

When I have this all worked out, would you like me to provide some sample scripts to you?

Yes that would be good, our main internet is provided wisp community wifi which connects to our ethernet, but because we are very rural and in the mountains, it disconnects frequently in bad weather, so then we got to use "mobile phone" 4g internet, thanks

@freeflow, my testing got delayed. My roommate was wrong - our second ISP is getting hooked up until NEXT Saturday, not this past Sat.

Still, I looked at NETSH and it's possible to to script settings to switch from one Internet connection to another, but it looks like a royal pain in the neck.

There are a lot of articles out there that say that you can backup a network configuration by using a command like this:

netsh interface dump > NetworkConfig.txt

This dumps a script which can then be used to restore those settings.
Unfortunately, I simply can't get the script to restore settings properly. I always get errors. I get the impression that this may have worked in earlier version of Windows (like maybe Win 7) but that this functionality has been neglected and not updated by MS.
