I see that your phone recently received an update.
You will likely find that other Wi-Fi networks continue to function but please inform us if that’s not the case.

It’s possible that the settings of your Wi-Fi router need to be adjusted, in particular for security and encryption. Are you familiar with how to adjust your router settings?
