You might want to look here, https://www.techspot.com/community/topics/i-want-to-connect-2-wi-fi-routers-to-create-2-separate-networks.152424/

There could be other configurations too. Depends on 'who' can see 'what' even. Like a USB drive on a router shared across all possible connections. I'll assume all want to use the Internet as well.

If the above isn't what you want, some Google searches might help you out.

Funny you mention that @IrvSp because that's all I have been doing this morning. 😂  I have not had much luck so that's why I am posting here.

That article looks promising!  Thank you for providing it.  I will see if I can use it when the new router arrives tomorrow and post here with any questions/success I have.  Thanks again!
