WiFi does not connect if the SSID is not broadcast.

I've updated to Sierra this afternoon. Everything seemed fine after the update. After dinner, my MacBook Pro (retina, 15 inches, beginning 2013) would not connect to Wifi. I reduced to a few things.

It wouldn't connect the 5 GHz n If the SSID has been hidden. If I admitted the SSID to shown, it would connect without problems. It would connect to the 2 GHz band, even with the hidden SSID.

I did the typical SMC reset and reset the NVRAM. I deleted the files related wifi and restarted the router and the MBP. I'm obviously on now and the speed seems normal with no dropouts. I can't hide the SSID now and will continue to work until he's asleep; No dice after that without reactivation SSID broadcast.

Any thoughts?

See you soon,.

  • BlackBerry smartphone WiFi does not work most of the time

    It's like a broken record, I know, but my WiFi does not (most of the time).  It used to work well, but over time he works less and less! I use v5.0.0.979 (bundle 1607, the 5.1.0.177 platform and a Bold 9700)  I get the Green checkmarks for connections and WiFi and a white WiFi icon options.  If I try to use the browser of BalckBerry he started working in WiFi and I can see the blue WiFi on my router shows the data flow and then everything stops in for WiFi is concerned and after a period of time, it either expires or most likely to connect to the 3G network.  I used to (a 3 or 4 months) work just fine, but now very poor.  I tried another router and has the same problem.  I found no solution in the forum that makes my 9700 working properly.  If I connect to the weather apps Bug or Thomson Reuters. WiFi works great, load fast and I can see the data on my router blink indicating data streams, but whenever I use the BlackBerry browser, it won't work!  Crazy!

    I found the same thing as automatic power switch at night is interfering with connections no matter what I did. So I stopped using it and it works fine now manually turn it off. Not much extra actually works!

    just has got rid of the virus and responsible for all the disks but given the wifi does not work

    Hello

    Check with the system manufacturer or the actual WiFi device manufacturer and ask in their forums (if any)
    for problems known.

    Actually, try updating your driver:

    Control Panel - network - write down of the brand and the model of the Wifi - double click top - tab of the driver - write
    version - click the driver update (cannot do something that MS is far behind the pilots of certification). Then
    Right click on the Wifi device and UNINSTALL - Reboot - it will refresh the driver stack.

    Look at the sites of the manufacturer for drivers - and the manufacturer of the device manually.

    How to install a device driver in Vista Device Manager

    Download - SAVE - go where you put it - right click – RUN AS ADMIN.

    You can download several at once however restart after the installation of each of them.

    After watching the system manufacturer, you can check the manufacturer of the device an even newer version. (The
    manufacturer of system become your backup policies).

    Repeat for network (NIC) card and is a good time to get the other updated drivers as Vista like
    updated drivers.

    I would also turn off auto update for the drivers. If the updates Windows suggests a just HIDE as they
    are almost always old, and you can search drivers manually as needed.

    I have a problem. I recently bought Toshiba Portege M800-10Z and downgraded Windovs Vista to XP service pack 3. All right, but the WiFi does not work.

    I tried to upgrade the wireless Lan driver, but it still does not work...

    Is there someone who could help me with this issue?

    Thank you very much

    Hello!

    That you say with the WiFi does not work?
    Can you connect to the router?
    The WLAN card is recognized in Device Manager?

    To solve this problem make sure that you have the latest version of the BIOS. Check on the Toshiba site.

    Also disable features of security as a hidden SSID, MAC address filtering and so far away.
    Check if an update of the firmware on your router available.

    Good bye

  • HP 15 laptop: wifi does not work windows 8.1

    I have Windows installed pro 8.1. I was using wifi on this laptop, it worked fine. However, recently, I see that the Wifi does not work although he shows me the SSID of my network I used to use and also the SSID of the networks of neighbors. (It means that the wifi on laptop chip is capable of scanning the wifi signals and so it works). The same router from which all other Mobile tablets, my home laptop work are able to connect to the wifi network. Only on this laptop I am facing this problem. What may be a solution or what I should try. I tried the steps listed here http://www.fixedbyvonnie.com/2013/10/how-to-fix-limited-or-no-connectivity-wi-fi-issues-in-windows-8...

    Although I have not changed the default settings only steps above on blog, I tried to solve the problem. However, it did not work. Also keys function + F12 on laptop has no effect. The light on the F12 key is always on. However, it is possible to toggle the wifi in the bar of Windows 8.1 charms.

    What should I check?

    I bought an external USB wifi device that solved the problem.  The card wifi on laptop works well, but for some unknown reason, he is not able to connect to home wifi router. http://www.snapdeal.com/product/leoxsys-150-Mbps-Nano-WiFi/1179610?utm_source=earth_feed&utm_campaign=TopPerformersPLAScaling3000&utm_medium=CPC&utm_content=1179610&utm_term=, & campaignid = 350311165 & 28373951005 = adgroupid & adposition = 1o1 & network = g & device = c & targetid = pla-55251503741

  • Capsule WiFi does not

    A year and half ago we bought a new Mac and the Time Capsule (TC) to go with it. I tried to set up at the start and think about this topic, I do not think that it has never worked properly. I say this because we got a new modem without router because time Capsule has an inside, and we are unable to connect to wifi. I have a TB Ethernet connection and if I can get online in this way, but the WiFi does not work. Last night, I went through and set up and the WiFi worked, but today it no longer works and I can't seem to do it again.

    The indication of WiFi signal says I'm connected, on my Mac and on our phones, but when you disconnect from data it no longer works. It's very frustrating because I don't want to have to go back to a modem/router of the rental of our cable company.

    We have just upgraded to OS X El Capitan 10.11.6

    I'm pretty confident that the problem is with time capsule, the wifi works with the other router.

    When it worked last night I created everything from scratch. But I do not think that I would have to do every time I need to use the internet. I also tried to create a WiFi with a custom DNS but that doesn't work anymore.

    Any help would be appreciated.

    Thank you.

    Amazing!

    I am so embarrassed but understand that I would update in the case where everyone does the same thing.

    When I put in 1.5 years ago I went from ethernet cables. The Ethernet cable from the modem was connected to the LAN port and the Ethernet cable from the Mac was connected to the WAN. Once I put the cable from the modem to the WAN everything has worked.

    Sometimes, just come back to square one.

  • Satellite L670 - after Win 8 upgrade WIFI does not work properly

    Afteer upgrade to Win 8, the WiFi of my Satellite L670-128 has stopped working properly.

    The connection only works some time, usually only a few seconds before the connection is lost.
    After a few seconds or minutes the connection is restored, just soon to be lost again.

    Cannot download large files or even to see larger photos on normal web pages. Is there any Win8 driver for Broadcom coming 802.11n network card, or should I throw one 2.5 year old computer in the trash?

    Buy a usb-wlan card is not an option, as wireless mice is already "permanently" reserving one of the three usb ports and wlan card it would be just to the left...

    To my knowledge this L670 series isn t Win 8 taken in charge and this means that there is no special Win 8 drivers for this device, so I put t think you will find an another Win 8 driver for this WLan card.

    But do you really want to throw this laptop in the trash just because the wifi does not work properly running Win 8?
    The device was working properly under Win 7?

    I would recommend running a few Wlan test.
    For example; Disable wireless encryption on your router and Wifi connectivity with the open network do that just for testing purposes, perhaps you will need to change the type of encryption to test.

  • WIFI does not work on my Satellite L650D

    Hi all...

    On my laptop, the wireless light is orange and won t work...
    When I got the laptop connected to the Ethernet cable, it works fine but the minute that I remove it, it turns off.
    Anyone know my problem?

    Thank you

    Hello

    I guess that LAN connection works properly and you can access the internet using LAN.
    But the WiFi does not work even if the WLan light is on. Is this good?

    I m wondering if you have activated the WLan with the FN + F8 keys.
    Have you tried that?

    You have configured the WiFi network properly? I mean that you must make sure that you have chosen the good encryption (WEP, WPA, WPA2, etc.) and the right encryption password!

    You can also disable all the security settings on your router and was able to connect the notebook to open WLan but it must be done only for testing purposes.

  • WiFI does not work on Satellite M105-S1021

    My TECRA stopped with the BSoD (on another thread) and I had to leave my old Satellite M105 - S1021 and try and get it going again.

    WiFi does not work on this laptop, even with the switch at the front, running and when I put in a USB WiFI module with an external antenna I get a very bad signal from my router wireless in the next room< 20="" feet="">

    Hello

    I found the specification for this old Satellite M105 series data sheet:
    [Satellite M105-S1021 | http://www.csd.toshiba.com/cgi-bin/tais/support/jsp/modelContent.jsp?ct=DL&os=&category=&moid=1372978& rpn = PSMA2U & modelFilter = M105-S1021 & SelCategorie = 2756709 & selFamily = 1073768663]

    Looks like the laptop was equipped with a map of Atheros 802.11 wireless network b/g.
    If your internal wireless network card does not, even if you have enabled the external WLan switch, then I recommend check device manager first check that the area of Wlan Card network adapters usually map Atheros Wlan must be there if its not listed, install the Atheros Wlan driver

    In addition, next to the switch hardware Wlan, you need to activate the WLan using Fn + F8

    Regarding the USB dongle and a weak signal of Wlan:
    Well, maybe the USB dongle aerial signal is too low on the other hand you should test connectivity using 802.11 B or 802.11 G standard only

  • Satellite P500-1CK - WIFI does not work

    Hello

    I bought a Satellite P500-1CK with Windows 7 64 bit. Cause I don't need, I replaced it with Windows 7 32 bit and now my WIFI does not work.

    I tried many drivers, Toshiba drivers and Realtek drivers, old and new versions. Installed and uninstalled them again and again. But it does not work. In the Device Manager, there is no error and no question mark. The map will be displayed as a RTL 8191SE, it's true. I've identified the vendor & device ID also.
    The other FN keys works like a charm, but FN + F8 does not appear. The wireless switch is active and the led is orange.

    When I type "cmd" then "ipconfig/all" it will be only shown the PCI Atheros Gigabit Adapter with the IP address, but not the adapter WLAN of Realtek.

    Searched Google @ and spend hours and hours, but I am at my wits end... Please help me.

    funthomas22

    Hi funthomas22,

    And this doesn t work exactly?

    You see a WLAN in range?
    Have you looked for WLAN networks?
    Can you connect to WIFI networks?

    A point would be interesting: can you try the same thing with preinstalled Windows 7 64 bits instead of your own 32-bit installation?
    Therefore, use the recovery disk Toshiba to restore the version of the OS preinstalled. You will have a pre-tested Toshiba Windows 7 installation where everything should work properly.

    Check this box!
