13 VAIO duo wifi device disappears

I have the duo 13 red vaio edition and in addition to the very poor wifi performance, my SDIO card disappears from the Device Manager on once a week.  I need to reinstall the driver to help my computer "find".

Is the wifi device: Broadcom 802.11abgn Wireless SDIO Adapter

Driver date: 17/06/13

Driver version: 5.93.98.4

When he disappears, I can't see all wifi networks.  The device is MISSING from Device Manager and the only way to see this is to enable the devices hidden in the view menu.

Any suggestions on how to remedy without a reinstall every time would be very useful.  Thank you!

(Patches to the strength of the wifi would be useful as well, but there is another thread, I have taken on this topic.)

Hi, the driver you have is the last version of accredited driver Sony. I just want to know a bit more about what is happening on the part of driver wifi. We received many comments on the wifi feature (which can be caused by the driver being "hidden" in the Device Manager) lost until you restart. It is an accident in Win8 across all series Vaio models. When the device becomes hidden in Device Manager and when the computer is unable to see wifi networks, it also loses the switch "wireless" in the settings of Windows 8 PC? If this isn't there, say, just plane, Bluetooth, NFC are the only switches, you just need to restart the computer. Reinstall the driver causes the computer must be restarted. If restarting the computer, the problem is mitigated until its next occurrence. This question is quite different from the wifi signal that is covered in a different thread.

    Hello Sean,.

    Thanks for the post.

    Download and install the wireless driver once:

    If the problem persists, try the following steps:

    http://www.KB.Sony.com/selfservice/documentLink.do?externalId=C1023252

    Alternatively, you can try the following steps for wireless connection problem:

    1. Turn on the wireless network adapter using the SmartWi connection utility.
    2. Disconnect the power from the router and modem, if they are separate devices, wait a minute and then reconnect power. Wait for the lights on devices to indicate connection was established and then test the connection.
    3. Configure the autoconfiguration WLAN service to start automatically.
    4. If possible, try another computer on the wireless network.
    5. If another computer is successful, this will ensure that the problem is not with the ISP, modem or router.
    6. Disable the setting for the wireless network adapter power management.
    7. Repair the wireless connection.
    8. Disable the Internet Version 6 (TCP/IPv6).
    9. Computer to start in safe mode and test wireless connection in Internet Explorer.
    10. If the connection works in safe mode, problem is probably caused by software anti-virus or anti-spy.
    11. Check the IP WAN address of the router according to the manufacturer's instructions.
    12. If the router does not have a WAN IP address, problem is probably caused by a problem with the ISP.
    13. Reset the router or modem according to the manufacturer's instructions.
    14. Check if wireless interference are the origin of the problem.
    15. Setting parameters try on WLAN router, such as the frequency of wireless channel or the MAC address cloning.
    16. Change of wireless encryption protocol can solve some problems.

    In case, if the problem persists, restore of the system at any earlier date.

I know it costs a lot of sales because after that the first few people complained of problems WIFI abot on Amazon, people stopped buying them.

  • VAIO DUO 13 slow Wi - Fi - is there a fix available?

    Hi all

    A month ago I have a VAIO DUO 13 as a gift from my father. From the beginning, I liked the design and the performance of this great device. However, I noticed that the WiFi signal is too weak, and data rates are really slow.

    The DUO 13 connects to my router with slower speeds from other devices I own, even from the iPhone 3GS or a laptop of 5 year.

    We took the first DUO return to the store and asked a new, and after almost half a month, I got a new 13 DUO.

    But once again, the SAME PROBLEM! Other owners are having the same problems?

    SONY has announced or informed a fix?

    I really think that to ask for a refund.

    Thank you

    Can someone answer please?

    To summarize for those who want a short version:

    a. my touch screen of this device is * outside? Any way to reinstall the driver for the touch screen? Tech Sony said that the material is very good.

    b. in my efforts to solve the problem, I turned off a device in Device Manager and it now gone, no way to recover?

    Here is the full version:

    I have a Sony VAIO Duo svd11225cxb. After the recent updates, freaked out and kept touch screen back to the menu screen to start (and possibly other areas of the screen).

    We decided that so that the computer to operate, it should disable the touch screen. So we went to the Device Manager and disabled the "usb input device" under "human interface devices" which associated with the touch screen. Allow us went then back to him and found that the unit had disappeared from the Device Manager. I tried to install the next window touchscreen driver, but that did nothing. Any advice?

    Hi herschen,.

    Welcome to the community of Sony!

    Perhaps the question is just the driver. We will isolate the problem by following these steps:

    • Power cycle - turn off the laptop-> flip the unit and look for a button cell or a pin hole on the bottom of the laptop. Using a safety pin, press and hold the hole for 5 seconds.

    • Reset the BIOS to the
    • Go to Device Manager -> right click and Uninstall the driver/s under Human Interface Device (DO NOT REMOVE). Then restart the unit. The driver will be reinstalled.
    • Run the Windows Update and Vaio Update.

  • SONY VAIO DUO 13 - Auto rotation is not selected, and yet the screen is still running.

    I have a problem with the autorotation feature on my laptop sony vaio duo 13 hybrid. Auto rotation feature is disabled but my screen is always turning.

    How can I solve this problem?

    Thank you

    Rob

    This drove me crazy as well.

    The issue is that software Sony turns on automatically auto-rotation whenever reduce you the notebook in tablet mode regardless of any previous or current setting.

    I found a work around:

    Section of the Starter - 'Device Manager' - under the sensors turn off 'HID sensor Collection.

    Now, even if the laptop says automatic rotation of images... it will not be because it is not aware of his orientation.

    Peace finally...

  • Finger touch several fails on Sony Vaio Duo 11 running Ubuntu 12.10 (N - Trig DuoSense MultiTouch)

    Hello

    I recently bought a Sony Vaio Duo 11 Ultrabook / Windows 8 tablet hybrid. For my work, I need to use this device with Ubuntu Linux operating system. Most of the devices are fully supported by the kernel linux and ubuntu, but I have some problems with the touch screen. While ubuntu and desktop environment Unity support multitouch, and that N-Trig, which is the manufacturer of the tactile device mentions linux as an operating system supported on his web page, I get errors and wrong behaviour with her. I just describe the issue in this bug report on the ubuntu bug tracker (launchpad).

    https://bugs.Launchpad.NET/Ubuntu/+source/xserver-xorg-input-evdev/+bug/1121379

    I am aware that the camera comes with windows 8 OS and ubuntu or any other operating system is not officially supported, but I need ubuntu for my work, and it's a shame does not take advantage of all the features of this wonderful harware from Sony, due to a misconfiguration or a bad bug. I'd also like to mention that ubuntu OS is the 3rd most popular operating system worldwide, with continusly increasing adoption by users. It would be good for Sony to be able to verify that his harware is fully functional with ubuntu, as it would be to broaden its base of customers, including those who would like to run ubuntu on Sony computer devices.

    Help, advice or contribution from Sony or any member of the community of sony to study and fix this bug will be appreciated.

    Thank you.

    Thanks for your reply biege.

    I already contacted the people at the ubuntu community and watched in ubuntu forums and another ubuntu community support resources. The device is quite new and it seems at the present time there are only a few members of the community have ubuntu. I posted the problem here jump 1. To find other owners of 11 Duo who want to run ubuntu on it and 2. To make Sony associated people aware of the problem, because they may have some technical knowledge than ubuntu and X.org community is missing at the moment and could deal with this issue much easier.

    By the way. A member of the forum who reads this and want to run ubuntu on Duo 11 is required to press the button "Affect me too" on the page of the bug ( https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-input-evdev/+bug/1121379 ). This way we increase the "warmth" of the bug and thus increase the possibility for technicians and developers ubuntu for the note and get to work with her.

  • Dead on some-olden days Vaio Duo 13 pixel

    Hello

    I bought a laptop Sony Vaio Duo 13 (model SVD13211CGB) on December 23, 2013. It's only a few days and I noticed a very distracting dead (not stuck; it is black) pixel on my screen. I had planned to have this laptop for the rest of my university studies (5 years) but it's hard enough because I already discovered a flaw.

    I live in Australia and plan receive a replacement (I also bought a 3 year $300 warranty "premium service" from Harvey Norman, the retailer from whom I bought the laptop). Should I go directly to Sony or I receive the replacement from the dealer, Harvey Norman?

    Thank you in advance.

    I suggest you return to the shop on the receipt that you bought with and they should be able to give a replacement. Alternatively, they can send the Sony laptop in your name (of course, you'll save on shipping).

    Computers are very different from back of other small electronic devices because they are often repairable and therefore its likely Sony will be who you should contact. First of all I would jump to the place of purchase if as you are within your 30 days while they could swap just with a bit of luck the case if it goes to Sony it may take two weeks or more...

    Before you do, try aome dead pixel software such as http://www.jscreenfix.com/ of fixing...

  • Several Airport Apple ID devices disappear shared devices and Software Configuration of the airport

    We have three Airport extreme and two Airport Express devices in two offices in the city.  Some time in the last two days, they all stopped appearing in the sidebar of Finder 'Shared' category (if they had attached disk storage) and they stopped from appearing in the Configuration software of the airport on any of the Mac on these networks. (They always seem to be correct, routing traffic, however).

    For a while, we left a desktop completely alone as a control group and did all our testing and troubleshooting in the other office.

    We-hard reset (to the factory configuration) all devices from the airport to an office. They began to appear again. Then we started to re - configure them again.  At the time wherever we had updated the devices they had disappeared again.

    So, another factory discount based configutations for each device to this facility. Then we added slowly in pieces of their configuration.  When airports have received Apple ID and associated passwords for associating with iCloud/BackToMyMac/WideAreaBonjour (depending on what you want to call it), the airport devices disappeared from the airport Setup.

    If we tried to configure another device from the airport to extend a network of 'invisible' airports, the new airports were "unable to find" one of these networks to expand.

    If we reset all devices without providing them with Apple ID and passwords, they worked mainly as you would expect. The main difference being now do not appear as having been recorded as BackToMyMac/WideAreaBonjour devices.

    One side for people dealing with this note: If your router are invisible, but they are configured to be configured from the EXTENSIVE worldwide network, you can use "File-> configure the other" and specify the address WAN of the missing aircraft and get this screen access as one would generally. From here, remove all the Apple ID associated with these devices, press "Refresh" to save the settings and they seem to reappear magically in the Configuration of the airport software.

    In that State, storage seems to be available, but only for devices in Domain Local (direct connection). Airports without AppleIDs will not appear in the field to iCloud/BackToMyMac/WideAreaBonjour, and it's as expected, given that these IDS is the means for the identification of their field.

    If someone else has noted these behaviors and if so, have an idea about specifically when they first appeared? Is there by any chance someone who knows of any change in registration or the MWAC of multiplication?

    Did you approach the problem exactly as I did in the past, and having encountered problems of the CCMM literally every version of OS X. They were all distinct problems with individual characteristics, and in some cases the solutions exist. Having said that the CCMM has been completely reliable recently - which means running the most recent El Capitan release on all my Macs. The initial versions (i.e. OS X 10.11 to 10.11.3 maybe) didn't work at all. I don't know which version fixed whatever the problem was, I am sure he has not worked for someone else.

    The same real place with Yosemite and previous versions as well. CCMM did not reliable until the exit "point three or four."

    Through these experiments, I believe it should be a pretty fast connection. If the connection between a Mac and all the others does not meet this requirement (whatever that is) all you will be able to determine, it's that the CCMM fails.

    Apple is characteristically silent about the technical aspects of the CCMM, probably because of security concerns. Nobody outside Apple knows how it works. If you're still having problems, I encourage you to contact them. After mentioning predictable you corrective raw materials (the two following links) you will be put in touch with someone who will look to what is false, providing diagnostic assistance and send your information to engineering. If it's something they should fix, you'll know not to the point of an OS X update is published.

    With all the conversations I had with Apple on this topic (which were many, involving a large amount of tests) not once they disclose any causal factors individual, other than to reiterate the need to run the last OS X, versions and the latest versions of firmware for their routers. In your case, that means probably that your Mac update to El Capitan. It is after all the very first recommendation in their document of support above, until you do this you will still not get in step 1.
