Unable to Connect Google Home Mini - Time Warner Internet

This question is about "Unable to Connect Google Home Mini", with Time Warner Cable internet and apps. AT&T worked fine plug and play. but Not that I just moved over to Spectrum my 3 google homes are not working. They can not connect to the WIFI. I talked to Spectrum 3 times, and asked them how to change setting in their own routers and no one in this company seems to have any clue on there own routers. Please post a solution once you have it.
