My iphone 4 doesn't want to pick up Wi-Fi?

I had an iPhone 4 for the past few months and the Wi-Fi works great everywhere I go that has Wi-Fi. Unfortunately it broke a few days ago and i got a new phone, another iPhone 4. No matter where I go, it doesn't pick up Wi-Fi. There definitely is working Wi-Fi where I'm, because I've been using it for months and also at the moment.
the Wi-Fi on my phone is ON.
the Wi-Fi router is WORKING.
i tried resetting network settings, it did nothing
i tried resetting all settings, still no Wi-Fi.
anyone have any suggestions?

Did you put in the Wi-Fi password.

That also happened to my iphone 4. What i did was i sent it to apple and they gave me a new and working one.

It isn't a new issue, see http://www.zdnet.com/apples-ios-6-wi-fi-problems-linger-on-7000004799/
Particularly with iOS6! Go android, just kidding about that but they do connect to Wi-Fi better.

  • Would an iPhone 3gs pick up 4g service on tmobile? I have a jailbroken, unlocked iPhone 3gs that I used to use with tmobile. Before, I only received EDGE service no matter where I was. This was before tmobile began carrying the iPhone on their network. Right now I have an LG Optimus L9 and it has 2 gigs of storage on it so I'm wanting to change to the iPhone if the phone will get better service than EDGE. So, now that tmobile carries iPhones, will mine receive better service than before tmobile carried iPhones?
  • What to do with found Iphone if the owner won't pick it up? I found a iphone at my cabin a few months ago, we plugged in in found and the owner. We messaged her on facebook, called her, texted her and did a lot to get it back to her. We finally got a hold of her through email. We have been waiting to hear back from her. I would go drop it off to her but she lives a hour and a half away. What do I do with the phone if she hasn't already came and gotten it? What do we do with it?

  • My laptop can pick up my Wi-Fi, but my iphone can't? My house has two stories, when i'm downstairs my iphone can pick up my Wi-Fi very fast and easy, and i always get strong signal. Same with my laptop. The only difference is that upstairs or downstairs, my laptop can pick up a good Wi-Fi connection. But its hard for my phone to pick up a signal. I was just wondering why? Also, the second story to my house was added on, the house was originally a one story. I don't know if that makes a difference, but thanks in advance
