Why can I log into my Wi-Fi on my laptop but not my IPhone?

It asks me if i want to join the network but when I type the password it says "incorrect password".
I know the password is correct.
I have restarted both my phone and the base many times.
I have tried to update it, it says "unable to check for update.

I have an Iphone 5s

What do I do?

If Apple Inc invents an I-Gun will you buy it to protect yourself?

These smart guns would be like wired to your iPhone with an app and then you charge your I-Gun and you can tell Siri to fire a warning shot to protect yourself

It would have a feature where if someone has a gun and fires a shot at anyone else in the room Siri will return fire at the gunner

Someone stole my iphone and turned it off. Can they do anything with it?

I was at a festival and someone swiped my phone and immediately turned it off so I can't locate it with find my phone. I switched it to lost mode and it hasn't been turned on in 2 days… Is there anything the thief can do with my phone or is there anything I need to worry about? And is their any way they can break into the phone or even use it? Just not sure why someone would go around stealing phones with zero benefit besides maybe selling it for parts.
