    No good on airplane mode either, looks like more people are having this problem after update 4.3.2

    Thanks for trying. I've been doing a fair amount of research on this problem, and I read that people have been turning off cellular data. These people claim that while they have cellular data turned off, the problem does not persist. Obviously this is not a fix, but could have provided another clue.

     

    Thanks for trying. I will continue to research this problem.

    Just to gather some more information on the problem, Could those of you that know, please inform me what Security Mode/Protocol your router is currently using (WPA2, WPA, WEP, etc). If you are running WPA2, try changing it to WPA and tell me the results. If you have questions on how to do this, please ask and I will do my best to inform you your specific router. Thanks everyone for your patience in dealing with this issue.

    There could be any number of issues regarding not connecting after an update. Similar to Greg stated, if you are using a WEP Key prior to the update, you probably WILL want to change the key to WPA2, best option? Make it a personal WPA2 key. Alternatively it could be that the Router Firmware needs updating in order to match the iOS Update. Or you could be using MAC Addressing on the Router. There are quite a few  options that can and will effect the connection.

     

    If, as stated, the iPhone works fine on any other Network bar the Home Network it is not an iPhone issue specifically. It is a compatibility issue between the iPhone and the Network, 99% of the time being an issue with the Network settings.

    I agree with Korthal. Based on some research I've done, I'm starting to think the iPhone 4.3.2 and 4.3.3 updates may have some problems with a specific type of Security protocol. Would love to hear the feedback of those that are able to switch to a different protocol than they are currently on.

    Sorry, son has a Nintendo DS which only does WEP.

    Would you be willing to change your security protocol temporarily to see if it resolves your issues?

    On one router (d-Iink 655) am using WPA2. A wifi extender (Powerlink) is unencripted. I can turn off all encryption but I do not think that will  help. I live in the country so risk is small. I would see any one using the signal. My phones show connected to a good signal but then cannot access the internet. When I do connect, I lose the connection if I go out of the house and back in. Thanks!

    Turning on airplane mode allowed me to connect to the powerlink.Things have been so intermittent that I will continue to assesss if this helped or was a coincidence. Thanks.

    I got my iphone 4 only Friday and have the same problem as everyone else.

     

    I have tried all the suggestions above.

     

    I have lowered my router encryption to Wep and recreated Wifi on Iphone4 but it makes no difference.

     

    My laptop connects fine, the only alternative I can think is to turn off encryption altogether which I aint doing

     

    I dont want to sound hysterical but this is not a router problem in that it will probably happen with any router.

    ok airplane mode had allowed me connect to WiFI

     

    This merely confirms to me that this is not a router problem and is not a satisfactory solution is it?

    Hi Guys,

     

    after a morning of no help from apple i have took the advice from one of the lads in the Apple store Gateshead big thanks to him at no charge.

     

    We all have the sam problem. All i did to resolve it was a RESTORE via Itunes ******BACK UP ONLY*****

    Before i did this i checked my WI-FI connection deatils.

     

    in WIFI network settings under IP address there is a tab DHCP that lists my

    IP Adress

    Subnet Mask

    Router

    DNS

    what seems to have happended since the new update the ROUTER AND DNS setting were missing. I RESTORED via Itunes ******BACK UP ONLY***** and now these setting are back and my WI-FI is working.

     

    Pls let me know it this works for anyone else

     

    Cheers

     

    Paul B

    What do you mean "Backup Only" ? I do not see that option in iTunes.

     

    thanks
