When I connect to my Wifi at my house and then open safari, it says "Safari cant open page because it is not connected to the internet" Why is it doing this? It shows on the top left that my iphone is connected to the wifi, but it is not letting me connect on wifi

thanks

    This is a common problem that a lot of folks are experiencing. I talked to a Apple Rep over the phone and they couldn't fix the problem for me. Lets keep our fingers crossed that a fix is on its way.

    As far as I can tell, this problem still hasn't been fixed. I have seen a bunch of posts here about it, but unfortunately, not one consolidated thread that collects the different bits of information. Some people have solved it by upgrading the firmware on their router.

    I have an Airport Express with the latest firmware, so in my case it isn't the firmware. I was using an older type of security (WEP) so I used the Airport Utility to change the security to WPA (which is more secure). I read on another post that that had helped solve the problem for some people. It didn't really help for me. The internet connection would work, then suddenly it would stop working. In all cases, I have a full wifi signal, just no Internet.

    What always works for me is to turn off the iphone, disconnect the Airport Express for 10-20 seconds. Plug the Airport Express in again and then restart the iPhone. This is a pain though.

    Luckily someone else (in a thread I can't find anymore) said that assigning a static IP address helps. You do this by going into Wifi, changing to Static and then changing the last to numbers in the IP address. The address will look like 192.168.0.02 The last two numbers will be different, depending on how many devices are connected to the other router. If you change the last two to, for example, 07 then, assuming that number is not already taken, the internet connection should work again. If the numbers you choose are taken, you will know because the iPhone will not be able to connect to WIFI, and will switch over to 3G or Edge. Just go back and try a new number.

    As I said, this solves the problem for me, but only temporarily. But at least now when it happens I can get back on by just changing the IP again, and I don't need to go upstairs and restart the router.

    Unfortunately, the problem comes back several times a day. I cannot figure out if it is the router or the iPhone that is causing problems. However, I am starting to have a suspicion that it occurs at some point when I use Apps that access the Internet (by this I mean everything other than mail and safari). Today it happened just after I used Shazam. Yesterday it happened just after I used the App store. I wonder if other people have noticed this too.

    Has anybody tried to erase the iPhone completely (Settings > General > Reset > Erase All Content and Settings) and then, after that, restore the iPhone without installing the backup? If everything is erased then the phone should see the network without any pre-memorized setup... Or is the net address cache kept somewhere else?
