HT4623 cant turn on wifi

after i updated mt sofware i cant turn on my wifi, i did hard restart but still cant work

Hello seymore1,
You can try this:
Restart your iOS device.
Make sure that airplane mode is off by tapping Settings > Airplane Mode.
Reset the network settings by tapping Settings > General > Reset > Reset Network Settings.
This will reset all network settings, including Bluetooth pairing records, Wi-Fi passwords, VPN, and APN settings.
Make sure that your device is using the latest software. To do so, connect your device to your computer and check for updates in iTunes.
If you still can't turn Wi-Fi on, contact Apple Support: 1-800-275-2273 (United States)

  • I cant turn on wifi on ipad mini please help??

    Hi guys I cant turn on wifi on on my ipad ios 7 1.2 I try restore network and didn't work please help

    I Don't know what you did in order to restore your network. I'm not sure what that means exactly. But take a look at this, if your WiFi settings are greyed out.

  • [SOLVED]Cant Turn My WiFi Card On.

    Ok so this has had me puzzled for a while, this is the output from an lspci of my wireless card:
    06:00.0 Network controller: Broadcom Corporation BCM4311 802.11b/g WLAN (rev 01)
    So I load the b43 module and it appears to work fine, iwconfig can see wlan0 and so can ifconfig. My problem is that I cant seem to acutally turn the card on, meaning I cant connect to wireless networks. I know the b43 driver works as this is what I was using in Lubuntu. From what I can tell the only difference I can see between the modules loaded in Arch and Lubuntu (after greping b43) is the led_class (im guessing this deals with the wireless switch on my laptop, which is what I would like to get working). However I cant seem to find it anywhere in the kernel (might be me being a bit stupid) and there isnt a package for it in user repo's.
    Any help would be appreciated
    Thanks,
    Oz

    I am not certain, but I believe you can do all of that without actually loading the firmware to the NIC.  Did you install core/b43-fwcutter  ??
    Dmesg should have clues as to whether the firmware exists and was (or was not) successful loaded to the card when the driver started.
    Yes i have installed core/b43-fwcutter, and here is what dmesg says:
    b43-phy1: Broadcom 4311 WLAN found (core revision 10)
    Registered led device: b43-phy1::tx
    Registered led device: b43-phy1::rx
    Registered led device: b43-phy1::radio
    b43-phy1 ERROR: Firmware file "b43/ucode5.fw" not found

    b43-phy1 ERROR: You must go to http://wireless.kernel.org/en/users/Drivers/b43#devicefirmware and download the correct firmware for this driver version. Please carefully read all instructions on this website.
    Im currently following the instructions on that website and I will report back with the results.
    *EDIT*
    Ok so I followed the b43 guide from the wireless.kernel.org page, when I go to extract and write the firmware I get this error message
    Sorry, the input file is either wrong or not supported by b43-fwcutter.
    This file has an unknown MD5sum 80c7bb743de4025f57ac7166dac7bc4a.

  • I have an iPod touch 4th gen and it updated by itself to iOS6 without a wifi connection. When I unlocked it, it told me to connect to iTunes. So, I updated the software and when the update was finished, my wifi button was greyed out. I'm cant turn on wifi

    My iPod updated by itself without a wifi connection. It told me to connect it to iTunes so I did and I updated the software and everything. After it was updated, my wifi button was greyed out and I don't know why. I sent it in to get fixed and the Apple store did NOTHING. I still have about 48 days left on my one year waranty and I don't know what to do to fix the problem. Please, does anyone know how to fix this issue without selling it or replacing it? I've tried all the troubleshooting techniques and nothing is working. Someone help.

  • My iCloud Backup button is grayed out and i cant turn it on. All my devices are on Wifi. Help!

    my iCloud Backup button is grayed out and i cant turn it on. All my devices are on Wifi. Help! Both my ipad and iPhone

    A number of employers will push a security profile to your phone when you add their exchange account that prevents you from backing it up to iCloud.  They do this because they don't want confidential company information on another companies servers.  If this is the case, you will find a setting called "Profile" in Settings>General near the bottom.
    You would have to contact the company's IT department to confirm that they are preventing you from backing up to iCloud but that's normally what causes the iCloud backup setting to be grayed our or missing from an iOS device.

  • Wifi keeps on getting disconnected/ cant turn off iphone/ cant open messages

    My wifi keeps on getting disconnected ever since I updated my iphone to ios 7.2
    and when I go to settings, when I click wifi, my iphone hangs.
    i cant open my messages folder. it just shows a blank page...
    and lastly, I cant turn it off. no matter how long I press the power/lock button, nothing happens..
    I tried to reset it, but it cant detect my wifi connection, but my mac does..
    help??

    Force the phone into recovery mode, as described here, & restore it as a new device:

    When finished, login to iCloud.com & remove the phone from your daughter's account.

  • My wifi button stays grey cant turn it on

    cant turn wifi on

    My 4S had the same issue and its quite a headache
    Theres no fix to this apart from reset device which wont fix it, or try the blow drier and freezer method which turns the wifi on but only works for a short time
    If apple is reading this ive been using apple products for quite a long time, and ios7 is terribley waste of downloading  because from all the issues tbh apple should allow users to downgrade, and get new iphone 4s when wifi is greyed and warranty Is ouf of date, if I get another issue im diffently switching to android say goodbye apple!!!!

    The reapair shop is probably responsible. And now that you took it to a third party and not to apple store, Apple will not touch your phone at all. So you will probaly have to buy a new one or go back to the reapir shop and hope they can fix it.
