  • FaceTime fails with "WiFi Connection Lost"

    My Google skills haven't found any matches for this, but perhaps others have seen it in passing at least.
    I've noticed recently that I've been having problems with FaceTime calls to a friend of mine. For the past month since he got his iPhone 4, he'd end up losing the WiFi connection, but now it's happening to me, too.
    The symptom is that the FaceTime call will be going fine for a while, and then it will just hang with no motion in the picture from the other phone for about 10 seconds, then the phone will beep and display this error:
    FaceTime Failed
    WiFi Connection Lost
    <OK>
    At this point, I find that my WiFi indicator in the status bar is gone and replaced with "3G". It has indeed lost its connection to the WiFi access point (a Time Capsule).
    Going into the iPhone's settings, I see that it shows there that it is still connected to my WiFi network (showing a checkmark next to my WiFi network name, although it still says "3G" at the top). Cycling WiFi off and back on corrects the problem.
    My friend is also using his iPhone 4 connected to a Time Capsule, so we have similar setups. I'm beginning to wonder whether there's some problem either in iOS 4 or the Time Capsule that causes the wireless connection between them to disconnect in an aberrant fashion.
    So, anyone else seen or heard of this?

    FaceTime connection problems on my iPad2 was magically solved by changing the DNS number (in the Settings > Wi-Fi menus) to:
    208.67.222.222, 208.67.220.220
    (yes, there is a space after the comma, and a space after the numbers 7)
    I recommend that you write down your present DNS number for safekeeping before you make this change.
    I hope this solves your FaceTime connection problem!
    All the best,
    Brad P.

  • Wifi connection lost after sleep

    Hello guys,
    I have a MacBookPro retina 15" and every time my mbp go in sleep mode it lost the wifi connection...
    Someone solved this issue?
    bye bye,
    Oscar

    Test after taking each of the following steps. Back up all data before making any changes.
    1. Make sure the network is on the preferred list by following these instructions.
    2. Follow the instructions in this support article under the heading "Symptom: The network connection drops unexpectedly."
    3. Make a note of all your settings for Wi-Fi in the Network preference pane, then delete the connection from the connection list and recreate it with the same settings. You do this by clicking the plus-sign icon below the connection list, and selecting Wi-Fi as the interface in the sheet that opens. Select Join other network from the Network Name menu, then select your network. Enter the password when prompted and save it in the keychain.
    4. Launch the Keychain Access application. Search for and delete all AirPort network password items that refer to the network. Make a note of the password first.
    5. In some cases, the problem has been resolved by repairing permissions on the startup volume.
    6. Reinstall OS X.

  • WiFi connectivity lost if not on Line of Sight

    HP Pavilion 15-e015tx Notebook PC
    Model: E3B55PA
    This laptop does not connect to the internet once it goes beyond a range of 4-5 metres of the router and especially when there is a wall separating the router . The signal strength also appears to be weak. I have tried installing the latest drivers available and even that doesn't help.
    This may seem a router problem at first, but I have tried this with different routers with varying capacities and it still persists.
    Whereas, all other laptops(even an another HP pavillion 15), smartphones and tablets connect pretty easily at the same locations.
    I am very sure of this being a hardware problem.
    How to proceed from here on?
    Regards
    Vivek

  • Why is wifi connection lost after sleep/wake mode?

    I've had this iMac a little over a year and had not experienced this until a few days ago.  Every time my computer comes out of sleep mode the wifi is no longer connected.  I must turn it off wifi and turn it back on again to re-establish a connection.  Any suggestions? Thx!

    Hello tim290,
    After reviewing your post, it sounds like after the computer wakes from sleep it does not connect to the internet. I would recommend that you read this article, it may be able to help the issue.
    Wi-Fi: How to troubleshoot Wi-Fi connectivity - Apple Support
    Symptom: After restarting or waking from sleep, my computer might not connect to the Internet
    After waking from sleep or starting up, your computer may not show that it is connected to a Wi-Fi network.
    After start or wake, your computer may indicate that it is connected to a network, but does not connect to the Internet.
    Solution
    Use these steps if your computer does not automatically connect to your desired Wi-Fi network.
    Check your TCP/IP settings in the Network pane of the System Preferences. Click the "Renew DHCP lease" button
    Choose System Preferences from the Apple menu.
    Choose Network from the View menu.
    Select Wi-Fi, then click the Advanced button in the lower-left hand corner of the screen.
    Click the TCP/IP tab from the top of the screen.
    Click the "Renew DHCP lease" button.
    Select the Wi-Fi tab and view your Preferred Networks list.
    Select each network and click the minus (-) sign to remove those networks from your Preferred Networks list.
    Click OK and close the Network preferences.
    Remove your stored network passwords using the Keychain Access Utility.
    Open Keychain Access from /Applications/Utilities. Your window will look like this:
    Remove your AirPort network passwords from the login keychain: Select the "login" keychain from the Keychain sidebar. Click the "Kind" column to order the list of keychain items by their type. Remove all entries of the kind: "AirPort network password".
    Remove your AirPort network passwords from the System keychain: Select the "System" keychain from the Keychain sidebar. Click the "Kind" column to order the list of keychain items by their type. Remove all entries of the kind: "AirPort network password".Note: The above steps will remove your Wi-Fi network passwords. If you do not know them, or if your network does not use passwords to restrict access, you should contact your network administrator.
    Restart your computer.
    Join your Wi-Fi network. You will need to enter your password for your network again if it requires one.

    Have a nice day,
    Mario

  • Wifi connection lost after sleep in mountain lion

    tried deleting all known networks and wifi services and reconnecting, but there is no improvement.

    I was having the same problem after upgrading to mountain lion.
    What i did was in Finder went to /Library/Preferences/SystemConfiguration/  and deleted all the networking plists (refer screen shot). Then restarted the Mac and in Network Preferences reconnected to my WLAN.
    That solved the problem.

  • TS1398 Updated to ios6 now lost all wifi connection both iPad and iPhone no longer connects to wifi

    Updated to ios6 now lost all wifi connection both iPad and iPhone no longer connects to wifi

    not much response in here which surprises me...
    Anyway... AS I am still looking for answers, I will share a couple of points that I realised...
    in Airport Utility, I noticed that my iphone MAC address was actually showing as client connected, despite my phone network showing the spinning wheel next to the network name for ever and never actually connecting.
    I am currently testing the router mode in Network to be on DHCP and NAT mode with a range from .2 to .200
    My phone is now connected....
    Everything seems to be ok and happy so far...
    strange that this router and phone have worked together for at least a couple of years, the phone works everywhere else, and all other toys connect to my WIFI just fine. the list is as follow:
    airport extreme
    Zeppelin air
    2x apple tv
    2 ipads
    iphone 4s
    2 mac
    1 pc
    I have litterally just hard reset the router with a pin just now as a last resort... same...
    I will leave the router as DHCP & NAT until a potential firmware or OS update...

  • Airplay mirroring problem:when i change slide mirroring from off to on ,my new i pad lost wi fi connection and apple tv lost wifi connection:ihave last software for both.Can u help me?thanks

    when i change slide mirroring from off to on ,my new i pad lost wi fi connection and apple tv lost wifi connection:ihave last software for both.Can u help me?thanks.
    when i use i pad with apple tv for see my photo,youtube and movies all ok.

    I suspect that the problem is in your router. Do NOT consider your router to be blameless if some other devices seem to work with it.
    Try restarting your WiFi router by removing power for 30 seconds. Don't just turn it Off. On many routers that doesn't really do anything but put the router into standby mode. If that does not help check for a firmware update for your router. If none exists which corrects the problem consider replacing the router.
    There is a chance that some services turned on in your router could be causing problems. Look for a setting called QoS (Quality of Service). If ON turn it OFF.
    If you need more help please give the make, model, and version of your WiFi router and how you have it configured.

  • My Macbook Pro i7 lost wifi connection

    Hi, my Macbook Pro i7 lost wifi connection. I don't know why, but my connection is lost every time. I've other PC, tablets etc. (Windows, iPhone, iPad) and all is ok. Only Macbook Pro i7 have this problem. Some help?

    Well if then, if it is two weeks old, I suggest a trip to the Genius Bar at your Apple Store... it may well be a warranty issue.
    I am sorry I was not able to be any help at all besides WANTING to!
    Were you running your other wireless machines at the SAME time? And you had nobody in the house using  mixers (for drinks or cake and cookie batter) or hair dryers? Clothes dryers....?
    While thinking of Brasil and weather- I saw on our public TV station a few months ago- a story about a fishing boat, I think south of Rio de Janeiro, who encountered a hurricane- and only one fellow lived. Ouch!
    Report back if you can save the link to the page, or the emails of the answers, to tell what the Apple store said...

  • App hung on "waiting"; during update, I lost my wifi connection; now cannot delete to reinstall (no X), syc does not help; itunes store says it is installed and I cannot reinstall; deleting from itunes and synching does not remove "hung app"; HELP

    App hung on "waiting"; during update, I lost my wifi connection and the app hung; now cannot delete to reinstall (no X), synching does not help; itunes app store says it is installed, therefore I cannot reinstall; deleting the app from itunes and synching does not reinstall the app on the ipod; the app developers have not helped and told me to check with Apple (which I am doing, since I am past my 90 day tech support). Hoping someone can help with this hung "waiting' app problem.

    - First try resetting the iPod:
    Reset iPod touch:  Press and hold the On/Off Sleep/Wake button and the Home
    button at the same time for at least ten seconds, until the Apple logo appears.
    - Next download the app on the computer and try to sync.
    - Last, restore from backup.

  • I am unable to get past the first step of Winston Churchill's answer because my phone says "checking for a software update failed because you are not connected to the Internet". Did my WiFi connection also get lost?

    I am unable to get past the first step of Winston Churchill's answer because my phone says "checking for a software update failed because you are not connected to the Internet."  Did my iphone's WiFi connection also get lost with the Contacts, Mail and Text Messages?  When I tried the software update, as recommended by Winston Churchill, the iphone was connected to my desktop which is connected to the Internet.

    You can't use your computers Internet connection to update your phone from the phone itself. If you want to use the computers Internet connection to update your phone you must update it through iTunes.

  • I have lost my WiFi connection to IPad2 other PC in house working help????please????

    I have suddenly lost my WiFi connection to my Ipad2.  WiFi is working on my husbands laptop fortunately so I am able to ask for help.
    I go to settings on my Ipad2 It picks up my home WiFi Network, when I touch the blue arrow key to the right it takes me to the IP Address page, and all these items are blank, i.e. Ip Address, Subnet Mask etc.  What can I do please, would appreciate any suggestions.
    Whoooooooooooooops, I do not believe it, my machine has suddenly(after 4 hours of trying via the Apple Help desk) - woken up and my Wi Fi is back on.
    Still I would appreciate if anyone else has had this problem, and could let me know what I have I ???? to make it happen, or rectify the problem, totally confused. but now  very happy. I love my Ipad

    Probably restarting your router by removing power to it for 30 seconds would have solved your problem.
