Latest firmware disconnects wifi

Every firmware update since 7.6.1 tends to disconnedt my mac from wifi. I have now tried every version but I have to roll back every time to 7.6.1. because that version seems most stable.

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, or by a peripheral device. 
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode and log in to the account with the problem. Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including Wi-Fi on certain iMacs. The next normal boot may also be somewhat slow.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin. Test while in safe mode. Same problem? After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of the test.

    Have you worked through the Troubleshooting iOS and WiFi knowledge base article?  If not, see if there is info in there that might help.
    Is the WiFi greyed out on all WiFi networks or just the one?  If it does this on all then there may be a hardwaer problem that needs attention from the techs at an Apple store genius bar.
    Before that, however, try a reboot by holding both the power and home buttons until the apple logo appears and it restarts, ignoring the red slider if it appears.  That clears a lot of iOS hang ups that occur.

  • Apple TV 3 (5.1.1) Home Sharing to Mac 10.8.2 consistently disconnects WiFi

    Hi All,
    I know there are several similar threads out there but none seem to have enough specifics about the situation for me to resolve it or trace the ultimate cause of the issue.  I am hoping if I lay out my setup someone
    The main problem is:  If I watch a TV Show / Movie via HomeSharing I can only watch 1-2 minutes before it disconnects.  Wireless drops and then restablishes on the ATV.  No other devices have connectivity issues with WiFi connection including 2x MacBookPro's and the MacMini running HomeSharing, iPad 3g, iPodTouch 3g, iPhone 5.  I tried several different shows and some issue with all.  So, I tried watching the same show which caused the disconnect via iCloud...  It works! Not a single drop out when watching via Internet.  But what about my non Apple purchased content...  I need this to work.
    Apple TV is running 5.1.1
    Mac Mini is running 10.8.2
      iTunes is 11.0.1 (12)
    Homesharing is turned on and enabled. 
    I have restored the image via Internet, I have reconfigured everything on the ATV.  I have ensured router and AP are running the latest firmware although I never had this issue on older builds of the ATV OS.  But I have updated several things in my setup recently (iTunes, Mountain Lion from Lion, ATV 5.1.1) and cannot pinpoint the cause.
    Here is my Setup.
    Apple Tv ----> Wireless AP---->Linksys Router------> Cable Modem
                              ^
    Mac Mini ---------|
    Both Devices connect at Wireless N.  AP shows good signal for both devices.
    My Final Step is to try and restore via iTunes but as I read this doesn't work with iTunes 11 I may have already exhausted everything I can thing of.
    Any other suggestions greatfully received.

    OK,  so I successfully updated the Apple TV via iTunes and USB cable.  Sadly it did not resolve the problem.
    45s into the show, it stopped and returned the main menu with WiFi disconnected.  5-10 secs later and it's reconnected and home sharing is available again.
    I then found these threads:
    1) https://discussions.apple.com/message/19750601#19750601
    2) https://discussions.apple.com/message/20506178#20506178
    I therefore tried the recommended "Downgrade" to 5.0.2 and can verify that it seems to be working!
    10mins in and no disconnect.  I will update after further testing.
    However If you find this thread, I would recommend downgrading to 5.0.2 from either 5.1 or 5.1.1
    Let me know how this goes for you.

  • Ipod disconnects wifi router!

    When i get connected to wifi with my ipod, after 2-3 minutes surfing web or just staying connected to internet it disconnects my wifi router, therefore i can't use internet on my PC which is directly connected to wifi router via Ethernet cable and the only way to get internet back on is to restart wifi router and as soon as i turn ipod back on it does the same thing again. does anyone know what i should do?
    Linksys SRX400
    Security Mode: WPA/WAP2 Personal
    Encryption:TKIP/AES
    ipod mac address permitted...
    ipod 8GB 1st generation ver 2.2

    First off, download the latest firmware for your router and install it. That may fix the problem. If it doesn't and the router is still locking up, you might want to invest in a new router but this does not sound like an iPod problem.

  • HT3728 Does factory reset go back to latest firmware update.

    I have resently updated my airport express to latest firmware. The airport express is configured as an extension to my wifi with an Extreme as main device.
    Shortly after the firmware update (1-2 days) the express stopped working and status light turned yellow.
    I have since then tried to do factory reset several times without getting the device up and running again.
    When doing factory reset the status light turns yellow after releasing the button and stays amber with short interval with green (1 second every minute or so)
    I have not been able to discover the express from my iPad, iPone or iMac again.
    Could the reaons be latest firmware update?
    Any advice to get it back to normal?
    Thanks,
    Per

    Does factory reset go back to the latest firmware update.
    A Factory Default Reset will not affect the installed firmware.
    Shortly after the firmware update (1-2 days) the express stopped working and status light turned yellow.
    A solid amber light is unfortunately an indication that the internal power supply inside the AirPort Express is failing, or has failed.
    I have since then tried to do factory reset several times without getting the device up and running again.
    The AirPort Express has failed, and will need to be replaced.
    When doing factory reset the status light turns yellow after releasing the button and stays amber with short interval with green (1 second every minute or so)
    This is yet another confirmation that the Express has failed, and will need to be replaced.

  • Internet stopped working on MBA after latest firmware update. Help please!!!

    Internet stopped working after installing the latest firmware update. WiFi still connects to router, our other mac desktop still connects to internet as usual (same network). I can't even re-install the MBA OS since it needs an internet connection!!!
    Any ideas?

    FIXED.
    I swapped our wireless router for a newer one, internet seems to work fine again (we were sent a new one by our internet provider which we never set up until now).

  • Attempted Iphone 4 update to latest firmware update "failed"

    Ive attempted to update the Iphone to the latest firmware update  and it has failed 3 times, the final time it looked as though
    it worked but stopped and went into new mode to go-back to Restore to old  setting. Now it is locked up and asking me for the  admin backup password
    and everything I've tried is not working..  Not sure what to do at this point.
    The laptop I'm using is a Panasonic CF29 and running Windows XP with SP3 installed.
    I'm  open to any ideas at this point.
                Thanks Artman

    Then it's pretty hopeless. Normally the error message remains displayed until you click "OK", so it's surprising that you didn't see it. You can try the shotgun approach; just try a bunch of stuff in the hopes that it will work. But first I suggest trying to update it again, and this time watch it. The following list covers the most common causes of update failures:
    Open a Command window and type the command "netsh   winsock   reset"
    Reboot your computer
    Disable your antivirus and firewall
    Launch iTunes
    Connect the phone using a USB port directly on the computer, not a hub
    When the phone is recognized in iTunes click on it, then click Restore
    If the phone is NOT recognized in iTunes, disconnect it, the hold the HOME and SLEEP buttons for exactly 10 seconds until the screen goes black, then release SLEEP but continue holding HOME while you connect the cable and continue holding HOME until iTunes recognizes a phone in recovery mode
    If the update completes you are in business
    You mentioned being prompted for a backup password. If your backup is encrypted you will need to know the password to complete the restore; if you don't know it you will have to restore as New and manually add your content back. If it is encrypted you really did enter a password for it once, whether you remember doing so or not.

  • Where is option to "disconnect wifi clients" from personal hotspot?

    According to this Apple Knowledge Base article, there should be an option in Settings > Wifi to "disconnect wifi clients" who are connected to the iPhone via personal hotspot: http://support.apple.com/kb/HT4517
    I do not see that in the Settings. I am on an iPhone 4, iOS 5.01, AT&T. Does anyone else see this? Was it removed in an iOS update? The KB article says it was updated December 14, 2011, so it should be pretty current.

    I too was looking for it and it's. It in my iPhone 4 AT&T 5.0.1 Perhaps it's not in this firmware update, in another location or apple decided to axe this option.
    Perhaps they reason that if you're going to disconnect all users, and leaving wifi sharing on was redundant as the wifi will cease to hotspot after 90 seconds anyways, it probably saves battery life... I dunno all I can think of.

    What's the latest firmware version for the Xperia Tablet Z?
    According to the Swedish and British Sony website, the latest version for the Xperia Tablet Z is 10.1.1.A.1.253 released on 17th of May.

    Depends on if you have the WiF version or the LTE version. For LTE the latest is 10.1.1.A.1.253 and for WiFi it's 10.1.C.0.344.

  • Download latest firmware for Toshiba 40RL838G

    Can anyone give me a link where to download the latest firmware for 40RL838G?
    I want to update with USB stick (no internet connection available)
    Latest firmware (in firmware information) is 6.4.0V.1, but TV has 6.1.oK.1 (21.Oct 2011)
    With this firmware I have problems with the channellist.
    Thanks

    I guess you will not find it for download.
    The info says:
    RL838/858 TL838/868 Energy efficiency updates
    Energy efficiency updates have been made to both the RL838/858 and TL 838/868 series. In order to update your TV with the latest firmware and take advantage of these changes please follow the below methods:
    *Please note, the TV must have an active internet connection in order to perform a firmware update.
    Connection to the internet can be obtained by LAN connection or by WiFi (using the required WiFi dongle)
    Connection can be confirmed by performing a Network Connection test. This can be done by selecting Preferences -> Network Setup ->Network Connection Test
    *Method 1:*
    _Automatic Network update_
    When the TV goes to standby the Network SW update is checked, upon power on of the TV the following message will be displayed (after 1-2 mins):
    A Software upgrade is available. Do you wish to upgrade? Yes/No, to update your TV select Yes.
    *Method 2:*
    _Manual Network update_
    In order to make the TV search for a firmware update at any point in time follow the below instructions:
    Select Setup menu -> Software Upgrade -> Select Network update
    The TV will then look on the network for new firmware and if available a update prompt will be displayed
    So you need to connect the device to the network

  • Using the latest firmware. My WRT54GS (connected through...

    Using the latest firmware. My WRT54GS (connected through a LAN cable) seems to randomely disconnect me from the internet for no apparent reason. For some reason, it can't find the DNS even though my cable modem shows that a connection is there. The only way I can get it working again is unplugging the router, reconnecting the, going into the router status menu and hitting DHCP release, then DHCP renew.
    I'm not sure whats causing this though. Any help would be appreciated.

    My GSv6  will function perfectly until my cable ISP decides to change my WAN IP address.   When they do that the router will drop internet connection  and I have to go throught the reboot process for the modem and router.  Sometimes this works and all is well again until the next ip change, but other times there are still sporadic outages.

  • My macbook pro screen remains grey after latest firmware update

    i just had the update notification for the latest firmware, proceeded to do so, and the screen remains grey, its been more than one hour and still grey, since its a firmware update i don't want to disturb it, but could it be that is taking so long?

    Reboot it by pressing the power button down hard to force a shutdown.
    If your still having problems, take it to Apple. I hope you have AppleCare becuase if they can't fix it, it's a new logicboard.

  • Zen Touch latest Firmware Update...player not connec

    I tried installing the latest Firmware update for my Zen Touch (released 2-09).
    The player is connected and recognized by Windows and the Media Explorer. However, when I try to install the new Firmware it keeps saying "player not connected".
    I tried d/l two different language packages cause I wasn't sure what counted - player language or operating system langauge. Anyway, that didn't make a difference.
    So what do I do? I have no idea where to start. It's firmware for the correct device connected through Windows XP.
    I have made a firmware update before, which worked fine. After that I updated the media explorer software.
    Help is very much appreciated! Thank you in advance.

    Perhaps it's worth making sure no software is using the player, so reboot the PC, and turn off the Creative Detector. Then try again.
