  • I can not connect to wifi using iphone 4s

    I can not connect to wifi using iphone 4s

    If this is you home wifi try resetting the router.  Turn if off at the wall wait a minute and turn it back on.  Are you sure you have the right password?

  • Unable to Connect to WiFi after iPhone power off; WiFi & internet are working with MBP; common problem, no solutions?

    Here's my setup: Internet <> Comcast/xFinity supplied cable modem <> new Apple Time Capsule <> iPhone 4 & MacBook Pro (see below for hardware details)
    Internet on my iPhone 4 has been acting slow since yesterday evening. My MacBook Pro was running fine, but just to be sure I checked the Comcast website to see that I have only used 50GB of my allotted 250 GB of data for the month, so it's not that.
    I decided it must be a problem with just my iPhone, so I opened up the multitasking bar and quit everything in there manually, and then I held the on/off button, and slid the slider to power off. When I started back up, I could not connect to the same WiFi I had just been using. I tried to reconnect and nothing. I tried to forget the network and try again, nothing. I tried to reset all network settings, nothing.
    I have tried all the steps listed here: http://support.apple.com/kb/TS1398 "iOS: Troubleshooting Wi-Fi networks and connections"
    Toggled WiFi off and back on
    Made sure I am in range of the router (it's about 8 feet away and my iPhone reports full signal from the network)
    Made sure all the hardware is connected and on
    Checked other devices (I'm successfully connected with my MacBook Pro right now)
    Checked for router firmware upgrades (I have a new Time Capsule from Apple with the current 7.5.2 firmware which I've been using for a month)
    Restarted my device (again)
    Checked that the network is available (it does show on my iPhone)
    Restarted my Time Capsule
    Checked my router configuration as described here: http://support.apple.com/kb/TS3727 "Wi-Fi: Unable to connect to an 802.11n Wi-Fi network" which involves simply checking to see that WMM is turned on, also stating that WMM cannot be enabled or disabled for Apple's AirPort products.
    Reset my network settings (again)
    I have searched and searched for fixes to this problem, and I have additionally tried:
    Enabling/disabling Airplane Mode
    Disabling any network password protection/encryption (no luck), re-enabling it (no luck)
    Changing the network password
    Checking for hardware addresses present in iOS Settings > General > About (they are present and not zero'ed out)
    Switching Bluetooth off (nothing) and back on (nothing)
    ....and probably a few other things I can't think of right now
    I have yet to try:
    The "Freezer Trick" which apparently involves chilling the iPhone to get a temporary fix?
    Restoring the iPhone (I would really rather not)
    A different WiFi network (other than my own Time Capsule home network or guest network, both of which give the same Unable to Connect error)
    So, after all of that, are there any more ideas? Is there a reliable solution to this issue? So far I've just seen a lot of "mess with the settings," "the freezer trick worked," and "blame it on the iOS 4 update."
    Here are my hardware details:
    iPhone 4; iOS 5; 32GB; AT&T; no cellular data plan (July 2011)
    TimeCapsule6,113; Firmware 7.5.2; 2TB (September 2011)
    MacBook Pro 3,1; Mac OS X (10.7.2); 2.4 GHz Intel Core 2 Duo; Hi-Res Display; 4GB RAM; 500GB HD (August 2007)
    ...and the Time Capsule config:
    http://cl.ly/BCUt

    Ugh. Apparently "messing with it" is still the answer. I decided to try the LinkSys router I was using before I bought the Time Capsule, and my iPhone connected with no problem.
    I went through the steps again, and after rebooting my Time Capsule this time, I can connect again. The troubling thing it that this started with a power-off of my iPhone. No changes or installations, just a reset. Am I going to have to reboot my Time Capsule (which has no power switch, just a cord I have to unplug) every time I reboot my iPhone?
    Jinkies.

  • Cannot connect to wifi on iphone 4

    All of a sudden, neither my wife nor I can connect to wifi on our iphone 4's. It is not my home network because I cannot connect anywhere. I got the most recent update but she did not. I have reset my network settings to no avail. still get message "unable to connect ..."

    I cannot connect to wifi on my iphone 4s. How did you solve the problem?

  • Cannot connect to WiFi on iPhone 4s

    Since putting my EE Sim into my iPhone 4s I can no longer connect to WiFi, what could be the problem and how can it be solved?

    Wifi has nothing todo with the SIM card or the network.
    Try a network reset on the device this will also reset the wifi.

  • MacBook won't connect to wifi but iPhones will?

    Help! My MacBook will not connect to wifi at home. All other devices do, but  none of the MacBooks. Weird, right? I've tried every fix I could find in these forums and nothing works. Diagnostic test says network is working fine...

    i sometimes run to these issues when i have my nieces and nephews visiting me and a lot of devices trying to connect to the same router - some will connect and others won't.
    I solved my issue by getting into my router's settings and changing the channel - under the wireless section.
    I also changed all my macbooks dns settings to the image below.
    give that one a go and see if that helps you out.

  • Cannot connect to wifi on iPhone 5s

    My internet connect outside is rubbish, but I cannot even connect to wifi in the house now!

    If the connection is poor, maybe this is the reason. But try to click on the name of the connection, otherwise press ask for connection, not automatical and do it again. Before these press the home button with the on/off button simultaneously to restar the device.

  • My MacBook Pro cannot connect to wifi but iPhone can

    My 2012 MacBook Pro won't connect to my wifi. My iPhone connects just fine, and my MacBook can connect perfectly to other wifi channels, just not mine. I have tried everything to get this to work! Can anyone help? It would be much appreciated!!

  • Not able to connect to wifi using iPhone 4 with OS5, sees the network but won't connect.

    Recently upgraded my iPhone 4 to the OS5 and I keep having sporadic issues with connecting to my home wifi, it sees the network but never connects.  I turned of Location Services and Cellular Data for that had worked sometimes, but now it just keeps spining and never connects.  I tried to reset network settings, reset my wifi router and reset my phone and nothing, it will connect at my church for example and other places but not at home.  I have MAC addressing security set on my router and I verified my iPhone MAC address is authorized.  Any other suggestions?

    Try restarting your router first, turn it off for a minute then back on. then go to settings on your phone, then wifi, tap on the blue arrow to the right of your wifi 's  name, then tap forget this network. Then go to the home screen, Then hold the home and off button down until the apple symbol comes up. Then go back into wifi and try to connect.

  • FaceTime won't stay connected on WiFi on iPhone 4 after iOS6 update

    My boyfriend and I both have the iPhone 4. We rely on FaceTime to video chat with each other as he lives in another city from myself and our daughter. We used FaceTime almost on a daily basis over WiFi prior to updating to iOS 6. Since updating to iOS6, neither of us can get FaceTime to maintain a connection to the other for more then a few seconds. FaceTime connects, then the screen goes black says reconnecting and it's a 50/50 guess as to whether it will reconnect and we can see each other for a split second before it goes black and reconnects again or just simply disconnects us. This has been happening for weeks now. I've been in touch with Rogers "technical" support and was told that since we only have iPhone 4 and are using FaceTime over WiFi that they can't do anything to help and I need to contact Apple as it's an Apple Server issue.
    Does anyone have any suggestions other then telling me to upgrade to the iPhone 5 so we can use FaceTime over 3G?

    So you're saying that it's only your phone that has the wifi problem? Like your friends are using the same wifi as you, but only you lose connection while they don't?
    If that's the case, does the wifi have a passcode? And also some wifi networks have a verification before the wifi becomes accessible. For example, you may connect to a wifi network without having to put a password, but then you would need to open Safari and you would need to confirm some things before you're able to use it. Like in college, the wifi is free and open to everyone but only students who have a user and pass are able to access the wifi.
    2nd possible solution is to reset your network settings. Go to Settings > General > Reset > Reset Network Settings. See if that works.
    3rd, restart your phone by turning it on/off.
    4th, restore your phone on iTunes.

  • HT1937 why when im not connected to wifi my iphone 4 will not let me facetime?

    When i try and facetime out side of my wifi area it will not let me connected using 3g

    Ask your cell carrier if they allow and support Facetime over their cell networks. Not all carriers do. If they do, check Settings/Cellular Data and see if "Use Cellular Data for Facetime" is turned on. If not, turn it on.
    Regards.

  • I can't connect to wifi on IPhone

    My wifi is just gray can't turn it on. I have done everything that I can think of. Anyone have ideas?

    Hi Zackfcb,

  • Can't connect to wifi. The iphone doesn't take the signal,

    Cant connect to wifi with iphone 4s

    On the iPhone, go to Settings > General > Reset and select Reset Network Settings.
    This will erase all saved wi-fi networks and settings from the iPhone.
    This will require re-joining every wi-fi network your iPhone has access to when returning within range of such a wi-fi network.
    If no change after this, try restoring the iPhone with iTunes as a new iPhone or not from the backup.
    If no change after that, the iPhone has a hardware problem.

  • My iphone is recognized as my wife's iphone by my computer. I believe this is preventing my wife from making necessary changes to her phone. Any thoughts on how to change the name on the computer?

    A few weeks back, I connected my wife's iphone to my computer to download an update. Since that time, wheneve I connect my phone, the computer recognizes it as hers. ITunes correctly identifies the phone, but the computer does not. Is there any way to change the name with the computer. I canot locate any way to do this.
    Thanks.

    i suspect that this problem is under windows, like mine, the solution was go to start/run/regedit and then look for the name that you want to change, for example, if your wife's name is susan, use the search option in regedit to look for every possible susan word you find and then chage susan for pete, if pete is your name. Only the Susans related to the iphone name, dont change everything with susan in it, is easy to know wich one is related to the iphone name, don't worry. This procedure worked for me. good luck
