WiFi problem after upgrade to OS 10.11.2

Hello

I have a MBP 2010 I installed OS 10.11.2 yesterday because it was supposed to improve the performance of the wifi.

Since my update the MBP does not see any network wifi more so that all of the other ipad and iphone at home are connected.

I don't know how to activate the wifi to work again.

Thank you for your help

You have restarted your Mac since the upgrade? If this is not the case, try this, because sometimes a reboot solves things.

You can also try a reset of the PRAM.

If none of the above work:

Try to turn WiFi off tension, and then back on... Or...

Attempt to remove networks that you have connected to in System Preferences/network/WiFi/Advanced button/Preferred Networks. Then see if you are able to connect to a network... Or...

Finally to try: System/Network Preferences, remove the entry from WiFi by selecting it in the networks list and clicking on the sign less . You may need to open the Panel with an administrator account and password. Then add the WiFi network, by clicking on the plus sign by selecting from the drop-down list WiFi Interface .

  • WiFi problem after upgrade to Windows 10

    Greetings!

    I read a few posts on WiFi problems after the (improper) upgrade of Windows 10. I have a ThnkPad T530 which I've upgraded to Windows 10 Windows 7 in September (too late to roll back). Here's my question:

    I have three computers on my desk. This standard T530 running Windows 10, a ThnkPad E555 running Windows 7 and a Dell running Windows 8. I used all three last Friday. I installed Norton on all three Friday and everything went without a hitch. When I first started their return to the top of this morning, the two others came online as usual. The ThinkPad T530 connected by a router in the company, but has no access to the internet. I can connect to the hotspot on my phone and it connects fine. I tried to turn the WiFi connection and then turn it on again, restart, by killing and restarting the business connection, etc. Nothing changes.

    Help, please

    Try the following:

  • Intermittent WiFi problem after upgrade to Windows 10

    My acer aspire V3 - 571 has been intermittently lose WiFi for the last 2 days since Windows 10 Windows 7 Home Premium upgrade.

    The Aspire has:

    Driver Atheros wireless network adapt AR5BWB222 10.0.0.38 Wednesday 2/15/12

    So far, I have:

    1. in the properties Atheros AR5BWB222 Wireless Network Adapter, I unchecked the box in the tab property management who read allow the computer to turn off this device to save power.

    1B. Made sure flight mode was in the off position.

    1 c. Forget exactly where I did, but made certain settings in another? location have been set to "Maximum Performance".

    2. check that the firmware is updated on my network router, the value 2 of WPA - PSK (AES) security.

    3. search through many forums to read the responses of people upgrading Windows 10 WiFi issues - seems it is a widespread problem, although no one said that the WiFi signal loss was intermittent, as is my laptop. Shots of the Internet for my research also shows WiFi problems occurred in the past for installation of Windows 8. (So far have not come across mentions of WiFi problems for the latest installations of Windows 7).

    4. in exploring my laptop, I came across a page of Microsoft Updates - SEE ATTACHED. I was surprised to find that these updates go out quite frequently during the day. For example, 10 separate updates between 23:30 and 16:24 on August 1 and 18 separate updates between 12 h 06 at 15:57 on August 2.  Included in the record of updates for August 1 and August 2. I am aware that Microsoft uses my WiFi to download updates AUTOMATICALLY. It is possible that this intermittent intermittent interruptions of the WiFi update download?

    5. this afternoon, when the WiFi did not work for Windows 10. I reinstalled as a dual boot Ubuntu 14.04. I have had no trouble to connect to the WiFi for Ubuntu.

    Not yet:

    1. I haven't tried connecting the laptop via an Ethernet cable to my router during one of these WiFi failure.

    2. my ISP is a VOIP/Internet, using a Westell and a single Cisco router configuration. I have not taken into account if they can be a cause of the problem.

    3. I read on a forum that someone corrected their problem with WiFi connection by changing their setting include TKIP security router

    NOTE: I need to put Windows screenshot attachment 10 updates in a response email separate to this post as this post does not accept the attachment.

    Would appreciate your comments and suggestions. Thanks in advance.

    I'll probably also put this on a Windows 10 forum elsewhere.

    Hello!

    FYI, this has worked for me, finally a solution!

    The strangest thing - I have uninstalled the driver Atheros. Do NOT reinstall it. After uninstalling the driver Atheros, a right screen Windows 10 panel immediately appeared style - either on advice of Panel or in the page settings of WiFi, was asleep, can't remember which - that contains an entry box marked my wifi password. I entered the password and boom, the wifi worked. He has been since.

    Once again thank you. Mark resolved.

  • Pavilion laptop g6 - Wifi problem after upgrade to 8.1 Windows

    KIM

    I have a Pavilion Notebook - C3M29EA #AB7 g6 and upgraded to 8.1 windows yesterday.

    Since then, I was unable to detect my own wifi connection while I am able to detect my neighbours. (Everything worked fine before the update).

    Any suggestions?

    -Same here.

    After an hour of time I will ever come back that I solved the problem.

    (1) go on the internet via the wired LAN port

    2) update drivers for Ralink wifi adapter

    Go: Right click on the wireless network connection icon: properties/Configure/tab Driverr/update driver

    (3) after a minute or two of updateing the PC reports that the driver has been updated

    (4) pull the network cable and turn on WiFi.

    What a pain in the anus,

    Anyway, as I said, corrected!

    Dansda.

  • Solve WiFi problems after upgraded 9.3

    After installing iOS 9.3 on my mini iPad, the device could not connect to my Airport network.

    The busy light was all the time spinnig, but the connection never got established.

    I could press the i key to display the IP etc but all entries were completely empty.

    I have zero network and turn on the unit and goes out, but not had any luck.

    I then abandoned static DHCP and all typed manually and suddenly everything started working, the busy flag disappeared and the symbol of a Wi - Fi connection appeared in the status bar!

    This seems to be a good workaround for now, maybe someone finds it useful.

    (2) if I use the latest Dell driver (IDT 92HDxxx HD Audio Driver) I hear initially via speakers, but as soon as I plug in headphones I can't switch back to the speakers (i.e. switching between the speakers and the headphones does not work) and my laptop computer microphone works.

    I would be happy to provide more information and help to debug.

    Hi, John. It's quite nervous of a member of the MS forum say that Dell is responsible to operate Windows. It wasn't Dell but MS who claims that Win10 has most of the necessary drivers and if not then the drivers Win7 and Win8.1 would work.

    johnsdagg
    I was hoping that maybe Dell could find in the goodness of their hearts to a updated driver IDT 92HDxxx... pretty please?

    I doubt that it is possible for two reasons. Dell went from IDT Realtek as the audio seller so probably not more a a contract with IDT, if IDT even exist anymore. A year ago IDT was acquired by another company. I do not know its current status, but it is sure that the acquiring company will not be upgrading old software IDT. Reference Dell itself does not write the audio drivers. Even when IDT was the seller I believe that Win7 drivers are the final versions - no version 8 or 8.1 I think.

    If I use the built-in driver to Win 10 ("high definition Audio Device") I hear speakers/headphones and switching between the speakers and the works of helmet very well but my laptop computer microphone does not work ("not connected").

    The native Windows audio driver can't stand struggling external mic. It is a MS 'known problem '. MS must implement a decision-making support, but there is no indication that it will be. Meanwhile, you have two workaround solutions. You can switch backwards between the natives and the IDT drivers. At some point Win10 could leave the IDT driver works correctly. Or get an outlet cheap usb audio to the microphone. Struggling running out-audio driver usb Windows native usb and so dependent no driver IDT.

  • Dell XPS Ultrabook 12 has network using WIFI connection problem after upgrade to Windows 10

    I have a Dell laptop XPS Ultrabook 12 that worked fine on Windows 8.1. When Microsoft prompted me to sign up for upgrade to Windows 10, I hesitated, but finally, I signed up for it. In recent months, I have been asked several times upgraded to Windows 10 but I just ignored and delay the update as much as possible, because I need to work with the laptop and I can't afford to have problems after the upgrade.  To my horror, Microsoft forced an install of Windows 10 this morning without allowing me to delay and just after the upgrade, I can't connect to my existing network. I have therefore no access to the internet and I am currently typing this complaint using another PC. I noticed that the laptop can connect to the network automatically when I walk my router but the connection will last only a few minutes, and then he'd cut off. I tried to connect and the message I get is "unable to connect to this network. I checked with "ipconfig/all", wifi said media disconnected. I checked with the Dell support website and downloaded and installed a newer driver, but the problem persisted. Apparently the surf on the internet, this problem is faced with a number and any suggestions to fix do not work (after that I tried).

    Help, please.

    You should be able to go back to 8.1 for Windows by following the instructions here:

  • iPhone 6s + had some problems after upgrade to iOS 9.3.2

    1st issue is the battery. Already before the upgrade to iOS 9.3.2 since iOS 9.3.1 my battery iphone 6 s + last latency time approximately 40 hours. Now after the upgrade to iOS 9.3.2,and it last only 15 hours. I noticed that the battery went from 100% to 60% in 8 hours without using it. I change all the settings after upgrade.

    2nd question is Siri Spotlight search Suggestion. I see more suggestion of Siri (recent call log and recent applications) in the Spotlight search. I also noticed that, to start the Spotlight search, I need to get to the bottom of the home screen. Previously on iOS 9.3.1 when I push upwards, search Spotlight is cancelled and return to the home screen. Now in iOS 9.3.2,and it no longer works.

    I also-hard reset by pressing Start button / stop and the "home" button together until I see the apple logo. Who will not help too.

    Have you checked the battery in use/settings/battery? All apps using the battery more than usual?

    If the power to restart the phone did not help, the next step after that which could be set back to factory settings and restore form the last backup, especially if you updated using the option 'Over the Air '.

    Use iTunes to restore your device to factory settings - Support Apple iOS

    For some users, removal and establishment of post counts once again solved the problem for others, connecting to iCloud and connect again after you stop the farm by a restart of drain.

  • TFncKy.exe problem after upgrade to XP SP3 on Satellite A200

    Hello

    After upgrade of XP SP3, I have problem with TFncky.

    _System_:
    A200/PSAE7
    -XP Pro (2 x with OS selector, 1 OS XP XP main, 2nd XP for games)

    _Problem_:
    After booting XP from my main XP installation I always get an error message pop up stating that there is no prob with TFncKy and TFncKy should be stopped. As "signature of the problem" I get the following:

    + AppName: tfncky.exe AppVer: 3.22.0.0 ModName: ntdll.dll +.
    + ModVer: 5.1.2600.5512 Offset: 00012ace +.

    With one of the following keys on keyboard always results in above described error pop up but key are functional:
    WinLogo, DEL, HOME, PGUP /-DN, END, right SHIFT, FN + keys F etc.

    My second installation of XP (Lite for games) short smooth after SP3 upgrade: no error TFncKy error message.

    As my second XP runs without any problems after SP3 I'm not sure if the proplem is related with + tfncky.exe + or + ntdll.dll +.

    BTW:
    What driver package includes "tfncky.exe? Toshiba controls?

    Thanks in advance for any information or advice for this problem!

    Best regards

    Hello

    the problem was already discussed in another thread: http://forums.computers.toshiba-europe.com/forums/thread.jspa?threadID=18082

    The last message was probably the solution for the whole of the case. The mentioned user that "TfncKy.exe" belongs to the Toshiba Hotkey utility that only needs to be removed and reinstalled for this problem.

    In addition, it would be wise to check the registry with CCleaner for example before you reinstall the Hotkey utility.
