There's no list of available Wi-Fi on my iphone?

I've been having this problem on my iphone for like months now. When I go to my Wi-Fi, everything there's just blank there's no list of available Wi-Fi. It just loads up for a quick sec and nothing happens.
I've been searching for a solution to this problem but there's none.

General > Reset > Reset Network Settings
(pass the confirmation prompt and restart)
tried Wi-Fi - no luck
General > Reset > Reset All Settings
(pass the confirmation prompt and restart)
tried Wi-Fi - no luck
General > Reset > Reset Network Settings
and it finally worked. But of course by this point all the customization under settings have to be re-entered.

Is there a way to manually enter the ID of the Wi-Fi?
