Satellite Pro L770-11F - loss of wireless connection

I have a portable Satellite Pro L770-11F recently delivered to me in the context of an insurance claim. It has an AR9002WB - 1NG Wireless Atheros adapt 7 is running Windows 7 Pro 64 bit.

The problem that I am facing is when I download a file from the internet, it stops at random points & is unable to complete the download.

I can't tell when it happens or how it goes as nothing comes on the screen to tell me any problem. Sometimes I find that even if the PC is always connected to the router (D - Link DIR-615 & only 6 feet from the PC) the map only shows theres no connection to internet even if my Xbox is connected & my phone connects.

What makes it more rare is that if I connect to the router via an ethernet cable it never is de-energized & download the files without any problems

The files I download are various sizes of 350 MB to 3 GB, but it seems to do more on files larger than 500 MB so im thinking it's a matter of time/timer or a problem of size of file (wireless only, not connected by cable)

I had a laptop before it & it worked fine & I have never experienced this problem never

I changed the power management settings in the option ncpa.cpl & bang as far as I can tell that the drivers are up to date. I'm sure it's a matter of PC and not my internet & hopefully this week I can you confirm that by connecting to an internet friends & see if the same thing happens.

Any help would be greatly appreciated I have about 14 days left before I can send it to the supplier for an Exchange if it's a hardware problem.

Thank you very much



You said that the Wlan driver is updated, but I recommend you also check Toshiba Wlan portal and compare Wlan driver versions.
Here you can find the latest version of the driver.

You should also check the Microsoft power management settings.
There is an option for the WLan to save the power of the dough.
I recommend to disable this option for better performance.

Last but not least, you can check and play with the options that are in
-> Wlan card device manager-> properties-> Advanced tab

Good luck, hope this can be a little help

  • OfficeJet Pro 8600 Plus: loss of wireless connection, printer does not accept the password wireless

    My printer has suddenly lost its wifi connection. It's the only phone connected to my network to do so.

    Through the Wireless Setup Wizard to restore the connection. Assistant tells me that I entered an invalid password wireless, that is not true. (I confirmed that all devices connected to the network using the same password).

    Reset the router (Technicolor of Time Warner). Reset the printer. The 'Restore default network' done. No luck.

    Zero has changed since yesterday, when my printer was working fine. I used the same router for months, do not change any settings. Any thoughts on what may be the issue? A bad update happen?

    Thanks in advance.

    My apologies for the late reply. I managed to get this problem resolved by phone to customer service.

    The security mode of the router had to be changed to 64 WEP for wireless connection to be restored. According to Support HP, it's a common problem with the routers in Technicolor. There was no explanation as to why the printer has suddenly lost the ability to connect wirelessly when safety was created to WPA2-PSK. The network has been configured this way for more than a year.

    I have almost solved this problem on mine (I had read about changing of security in a different post), but ran into a hiccup because of Safari. For some reason, Safari prohibited access to a menu page for my router security settings. You can imagine how boring it is to look at the HP Support use Firefox to access the router and do what a mouse click more, and then I had to make the change. So, if you make this change, be sure not to use Safari to access the gateway of the router Technicolor. Use Chrome or Firefox.

  • Satellite Pro L770-149 - cannot get working Wlan


    I recently rebuilt a Toshiba Satellite Pro L770-149 with windows 7 64 bit, when I installed first the operating system, all the drivers were missing so I installed all of the correct drivers and had run as it was before. Form Apart wireless connectivity,

    It can connect through the ethernet cable and wireless (Fn + F8) is enabled.
    Device Manager, it shows that all the drivers are correct and functional.
    The icon in the taskbar just like a Red Cross, unless I connect the etheret cable.

    Any Suggestions

    Thanks in advance for any help

    I think that support for laptop AR9285 WLan Atheros 802.11(b/g/n chip).
    Have you seen the Atheros Wlan card in Device Manager?

    If so, the WiFi card driver is correctly installed and if you have enabled the wireless network adapter using the FN + F8, then you should be able to configure the WiFi network.

    To do this, you must go to control panel-> Network & Sharing Center-> (left) choose manage wireless networks
    Now choose Add-> manually create a network profile
    Here, you can configure the WiFi using the SSID network and other options needed.

  • Re: Satellite Pro L770 - networks detected but inaccessible


    Yesterday I received my new toshiba, and since then, I can't connect to any wifi network. My model is the Satellite Pro L770. So I can find many networks, but when I try to connect to one of them, the connection fails:

    -My home network, which is of WPA/TKIP. I enter the password, and after several seconds, I have an error reported, with very little information about the causes.

    -A public network (free, a french access provider), which should actually connect and redirect me to an authentication page. But in this case, I have limited access and if I try to connect to google, I have a DNS problem, so I can't use public network too. Here, I get an IP address, but no gateway, it's maybe normal that I'm not sure.

    I must say that I have an Android phone with which I can connect to my own wifi. I tried to unplug, in order to avoid any conflict of IP, but the result is the same. My machines are ready DHCP, and my router has active DHCP mode.

    Any help would be much appreciated.
    Thank you.

    Hi lapsus63,

    Have you tried updating the driver WLAN and wireless network card appear correctly in Device Manager? You can download the latest WLAN driver on Toshiba WLAN official Portal:

    Satellite L770 is brand new model mobile phone, so there is not a lot of discussion about it here in the forum. What you can also do is disabling feature of wireless network adapter in the power management Windows for each power of energy saving profile.

    I hope that helps! :)

  • Satellite Pro L770 - 14 H - the use of WLan and Bluetooth at the same time

    I have a Satellite Pro L770 - 14H and you want to use a Bluetooth mouse.
    With the 'FN' and F8 key I am capable of coding between WLAN and Bluetooth, but it is not possibel to have both at the same time.

    My question is: How can I have WLAN and Bluetooth at the same time?
    To use a Bluetooth mouse with WLAN connection.

    Thank you very much


    Using Win 8.1?

    Usually you could turn on and off Bluetooth in Win 8.1
    Settings PC-> PC &-> of Bluetooth devices

    There, you can move the cursor to BT for THE position.

    I have instaled lastes drivers for it. I see in drevice Manager and seems to work fine but when I try to look for other wirless shows that this text "found no wireless networks in range.

    First question: this model of laptop is possible to have this part?
    Second: Will it work?

    Sorry for my possible mistakes with this post but my English isn't correctly. Plese give me a quick answer for her.



    As far as I know a few Satellite Pro A40 were available with WLAN connectivity and other models not so theoretically WLAN works with Satellite Pro A40.

    You have installed the card WLAN, you connect the two antenna WLAN (black and white) cables to the WLAN card?
    Or you didn t these antenna cables?

  • Satellite Pro L770 damaged TVALZ_0.sys driver - where to find?

    Satellite Pro L770 does not start after flashing the BIOS to version 1.3 and install the latest version of Toshiba Service station.

    According to the repair of the Windows system, the c:\windows\system32\drivers\tvalz_o.sys is damaged.
    Where can I find a new driver for tvalz_o.sys intact?

    I tried to repair using repair windows system, but failed.

    The autoinstall tool would provide a solution for my problem?

    I think that the TVALZ.sys file is part of the Toshiba value added package.
    This package is released for Win 7 as well regarding the old Win Vista.

    I think you should try to reinstall this package

    You will find this software on the Toshiba UE driver page.

  • Satellite Pro L770 - 12 p - Wake-up on LAN is not possible?


    I try to send a wake up message to LAN (WOL) on my laptop to propel to the top.
    I failed to make it work.

    But I do not see a strange thing happening: when I send a magic packet WOL while my laptop is running, the laptop restarts automatically after closing down.

    It seems that the Magic Packet is stored somewhere (perhaps in the NIC?) and is activated once the cell phone is off. I think a magic packet must be ignored when a machine has already begun and not be recorded and executed after the PC is turned off again.

    That being said, I did a test with another PC; I am able to send a magic packet via my business network. So the problem isn't somewhere else. But the BIOS of my Toshiba laptop does not pick up when the machine is off. Only when it is already running.

    Is this a bug and this bug can be resolved?

    Kind regards


    PS I have the latest version of the BIOS (v2.30) and I activated the Wake Up on LAN in the BIOS.

    Post edited by: avanzwol


    According to the Toshiba driver page, the last BIOS update was 09/03/12 and I doubt that this new version of BIOS which will be released in the future. The Satellite Pro L770 series is already discontinued.

    However, as far as I know the reactivation of the LAN option can be found in the properties of the LAN card.
    Go to Device Manager-> LAN card-> properties-> Advanced tab
    Here, you should check if the WOL is enabled.

    By the way: the network driver seems to be Realtek. I recommend you update the driver of network directly from the page of the Realtek driver. I know that WOL is controlled at the level of the BIOS, but I think the update is worth a try.

  • Satellite Pro L770-144: 8 card reader win don't recogize SD card

    My computer laptop ist a Satellite Pro L770-144 and the ist IO 8 Pro 64-bit Windows.
    The SD Card Reader recognize the cards. I had installed the controller with the 6.1.7600.30126 Version Realtek card reader a Windows 8.
    But the cards are not recognized.
    In Windows 7 it? works.

    Does anyone have an idea?
    Greetings and thanks
    Leo L.


    First question:
    Card reader is properly recognized in Device Manager?
    If it is not recognized, then you used a bad driver.

    If its recognized, the driver has been installed correctly and there is another reason why SD cards cannot be used.

    As far as I know the Satellite Pro L770 card reader manages different types of cards with different sizes.
    SD: 8 MB - 2 GB
    SDHC: 4GB - 32 GB
    SDXC: 64 GB
    Memory stick: 128MB - 256 MB
    Memory Stick Pro: 512 MB - 2 GB
    xD Card: No.
    Mini SD: 8MB - 2 GB
    Micro SD: 8MB - 2 GB
    CompactFlash: No.
    SmartMedia: No.

    As you can see the compatible SD card: 8 MB 2 GB
    It seems more large SD cards only are NOT supported.

  • Satellite Pro L770-14N - cannot find any drivers

    Hi all

    I bought the laptop Satellite Pro L770 - 14N PSK3TE. I installed a clean version of windows 7 ultimate, but I can't find any drivers for this model.

    For example,--> on page dowbload toshiba, is the required WLAN driver not in the download section.
    I have dl the driver from Atheros page.

    Find all the drivers, but we're missing in Device Manager.
    Is a driver package available?




    The Toshiba European driver page seems to provide all Win 7 64 bits of the Satellite PSK3TE L770 Pro series drivers.

    The WLan drivers can be downloaded here:
    This is the official Portal of Toshiba WLan and there you can also find Atheros Wlan driver.

  • Loss of wireless connection on Satellite Pro L10

    I have a Toshiba Satellite Pro L10, with wireless capabilities built-in. I recently bought an ADSL Modem Belkin Wireless G Router. My desktop PC can connect to the internet via cable and cannot therefore have my laptop. However, when I connect to the internet via wireless connection my laptop sometimes everything stops. This isn't something to signal that I'm only about 2 feet from the router, and it is not that I can't connect to the internet, as I am on this at the moment. Is that in a few minutes, the connection will be lost and I can't seem to find what I can do about it.

    The other problem is that when I click the icon at the bottom right of the screen, the "Wireless network connection" window opens. Here, it shows the wireless network I'm trying to connect and it shows with a strong signal, but it is almost always said not 'connected '. He said never 'connected', even when I am connected to the net and surf away!

    Anyone has any ideas at all?

    It sounds a little to the Wireless LAN card is unable to obtain a valid IP address.
    These interruptions may occur for different reasons.
    But especially the new version of the driver Wlan and/or Bios should help resolve these interruptions.

    What card Wlan do you use?
    If you are using the Intel Wlan card you can also visit the Intel Web site to download the most recent version of the WLan driver.
    Please also compare the BIOS version available on the Tosh site with the version preinstalled on your laptop.

    Wlan card properties contain some useful options that could improve the quality of the connection. Energy saving options should also be required to check other functions in the tab advanced and disabled.

  • Satellite Pro L300-1 b 9 cannot connect to my wireless router


    I activated the nw wireless on SAT L300 PRO 1 b 9 - but with a lot of struggle...
    First I had to find the switch to turn on (I never got :-)).
    Then I had to uninstall Atheros Windows and set flags on (activate) in the Windows driver.

    But in Linux and Windows, I couldn't connect to my wireless router.
    My luck was that some of my neighbors have a wireless network security-disabled, open, I could map to test.
    The test was succecfully with this network, but my wireless router was inaccessible.
    The other machine I could reach it.

    The result was:
    If I set the router to broadcast the SSID, the two OSs (Ubuntu + Windows) can use the wireless network.

    But if I turn off the broadcast (to protect my router), the network driver is unable to use my router, it does not matter I set the SSID...

    A router is WRT54G, and he works with other computers if I hide the SSID, but as Satellite Pro L300 unable to connect (with this option).

    Someone knows why? What should I do to I could hide the SSID to the bad guys?

    Thanks for any help!

    With regard to:

    I put t know what Windows operating system you use, but if you use original Vista, I think that, good WLAN driver is part of the package. For the wireless network adapter must be properly installed.

    It is not easy to say what the problem is here, but if the laptop can see and detect your WLAN network side laptop computer s everything should be OK. Try to reboot your router and check all the settings.

    In my opinion, there is a problem with the WLAN settings.

  • Loss of wireless connection casual on satellite C660-115


    I have a Toshiba Satellite c660 (2.5 years now, I think) and I have problems with my wireless connection (for 3 weeks now).
    Never had any problems with my connection before.

    When I use my laptop + - every hour my laptop disconnects Internet and immediately connects again.
    My computer is often used for playing games online and after 3 weeks, it's starting to annoy me, because I need to restart the whole game etc...

    Now, I have already updated all my WLAN drivers, I have the latest version of the BIOS update, and I adapted my energy profile settings to make sure that my computer is not turning off my wireless connection.

    I really think that the problem is on my computer because I have the same problem on 2 different networks.
    Don't know what to do, I hope someone can help me.

    Kind regards

  • Loss of wireless connection between Mac and Office jet pro 8500 has more

    My printer has been successfully implemented with my mac but loses the wireless connection.

    I'm on OS X Lion (but the same problem happened with Snow Leopard).

    My router is provided by BT Vision.  Also on the original hub is an apple TV and phone 3 handsets.  I don't know what channels to use them and do not know how to find out.

    Network Setup page shows no problem, but the mac cannot connect to the printer.

    Any suggestions please?

    If the printer has a valid IP address (not or 169.254.X.X) then it is always connected to your network.

    If your router is a BT HomeHub, you're not alone.  A lot of people on these forums have had trouble with them and most of them that I couldn't help.

    The only kill-TI-dead solution is to buy a standard router (Linksys or Netgear), attach it to your BT and connect everything to the new router.
