How to turn off alert asking if i want to share the Wi-Fi password on my iPhone?

My house wifi was temporarily down. Ever since it's been back, my phone asks if i want to share the wi-fi password with that network. It is driving me crazy. I don't understand any of the offered solutions. None of my household can help. It's annoying but what's worse is that when I am teaching online, and the prompt comes up, my screen freezes until I tell it to go away. This means fiddling with my tripod and disrupting my class. Can anyone help? Explain it to me like you're talking to a five year old....please.
