Iphone shows Wi-Fi signal, unable to connect?

My iPhone 4 is picking up my Wi-Fi signal from the router but when I go to safari, games, or FB its not uploading meaning that the Wi-Fi isn't actually connected. I've tried turning off the phone, resetting the router, nothing.

Try resetting your modem and your router then try it.

Upgrade router firmware.

Since you tried restarting your router with no luck and assuming your phone normally connects automatically with DHCP, try instead to manually assign yourself an IP Address. Look at your router settings and pick and IP inside your IP range.

  • Windows was unable to connect to thomson router? I accidentally turned my router off today for about 10 minutes (Thomson TG585 v7) and now I can't connect with any device at all, ipad, iphone, laptop, ps3 etc. I've gone through all of the settings in the router to try and configure it but nothing I do works. I've had this problem many times in the past but it comes back on and things can connect again… Sometimes, it's just unpredictable.
  • Unable to connect to iTunes Store? (Version 10.7)? Hi, I need help on how to connect to the iTunes Store with the 10.7 version. I've tried literally EVERYTHING, and I've even contacted Apple (they were of little help). The error code on it was -3212, does anyone know what that means? :/ Oh yeah, and yesterday I just got a new iPhone 4. Also, how can I transfer music and apps from an iPod Touch 4th generation to an iPhone 4?
  • Unable to connect to iTunes on certain devices? When I try to connect to my iTunes account on my iPod or my PC, it doesn't work. On the PC, it gives me error message 50 and says a network connection can't be established. On the iPod it just says "can't connect to iTunes store". I tried to connect my other iPhone and my iPad to the same account, and they worked fine. I know my internet is working. What's the problem and how do I fix it?
  • Unable to connect my iphone 4 to my home Wi-Fi? I just recently got given someone's old iphone 4, before i reset it i synched it up with my Wi-Fi jut fine, however when i put it back to the factory settings and tried to connect to my Wi-Fi it doesn't work, instead the wheel thing just keeps spinning round and has done for about an hour.
