Satellite Pro C660-1NR lose wireless adapter?

We bought a few of the above computers laptops running Windows 7, and I had problems with 2 of them so far! After some time of normal web browsing, I lose the wifi network and in the Device Manager, the Atheros AR938x card no longer shows as being installed (no icon or anything). After a reboot, everything is fine and the adapter shows as working normally. However, he can and pick up again intermittently.
It's frustrating when standing in front of a class of students in the middle of a lesson. The only software that has been installed is office and a couple of educational programs that work fine on other machines.
Any ideas before I throw them out the window?

Thank you

> Any ideas before I throw them out the window?
Yes. Contact the nearest Toshiba service provider as soon as POSSIBLE and leave check books.

All you can do is to install original recovery image (Win7) and test with the factory settings, but I don't think it will help.

  • Satellite Pro C660-1NR crashes intermittently, hard reset required

    Windows 7 64 bit Satellite Pro C660-portable 1NR

    Hello

    One of computer Laptop my users freezes at random times throughout the day. At first, I thought it was battery attached, as the first two occurrences that happened when using disconnected, but it has since then done when connected too. On average, it happens at least once a day.

    He will not resume later, the only way to get past that is holding down the power button then restarting.

    The problem started when downloading a number of updates from Windows about 6 weeks ago. Previously it has never frozen, not even once.

    I'll wait to die again (maybe today, maybe tomorrow!) and focus on the event log around the time he died.

    Don't you think that it is hardware or software related?

    I updated the drivers of the laptop, chipset etc, so everything is as up-to-date as I can get it.

    Nothing wrong with this laptop other than the gel, performs very well when it works.

    Your help is very appreciated.

    Kind regards

    So why you n t try to fix the system to the point before the updates were installed? I think it would be the first step, try to solve this problem.

    > Do you think that it is hardware or software related?
    If the settings in the system at the point of early time would not help, I suppose that a recovery system would be the next step to find out the reason for this problem
    After the related question of the unit should work correctly if it could not well be material recovery

  • Satellite Pro A200-16YT - update wireless adapter card for 802.11n

    Satellite Pro A200-16YT (PSAE1E) with Windows XP Professional SP3 from the East.
    I tried to increase my existing 54 Mbps wireless network speed by replacing the Atheros AR5007-EG existing with 802.11n 802.11a/b/g more quick adapter.

    The Atheros driver is v9.2.0.439 (08/04/2011) it's later. I tried to install an Azurewave AR5BXB72 (Atheros AR5008) as a substitute, but without success. As well as trying the standard Windows wireless configuration, I used the Atheros Client Utility (ACU) which confirms that the card and the driver are installed and activated, but the radio does not, so no there is no association/connection to the wireless network!

    Reinstall the original AR5007 works without any problem. If someone experienced similar problems or can offer a solution, it would be greatly appreciated. Thank you

    Hello

    Not sure about this Wlan card but I read in the forum that some people had similar problems, allowing the new card Wlan.

    Check this thread for example:

    It seems that the problem is related to the assignment of the WLan card pins.

  • Problem WiFi on Satellite Pro C660-2TQ - lose the internet connection

    Hey people,

    hope you could help me. I did a new clean install of Win7 (32 bit) on my Toshiba Sat, C660-2TQ.

    His job very well, except one thing:
    the adapter Realtek RTL8188CE-in my laptop is just terrible...

    I installed the latest driver for this Home Premium wifi, but I lose the conn. to the internet all the time.
    While I have to disconnect in the bottom right corner my laptop and connect again manually.
    I have to do this every minute or so and its very annoying.

    I saw read several discussions about the problems with this specific wifi adapter, but no solution has helped me...

    I didn't install all the listed drivers (34 available for me) but then what I Normand to update my BIOS or would it be a driver as the driver for the touchpad is necessary to get my wifi working properly?

    Hope you guys could help me...

    honestly desperate

    cordially :)

    Hello

    WiFi disconnection problems have different causes and its not easy to say why it happens.
    So, you will need to check each step and each option.

    First of all, you will get the latest version of the driver for this adapter WLan on the Realtek driver page:
    [Download driver Realtek RTL8188CE | http://www.realtek.com.tw/downloads/downloadsView.aspx?Langid=1&PNid=21&PFid=48&Level= 5 & Conn = 4 & DownTypeID = 3 & GetDown = false & downloads = EU tr]

    Would recommend that you do not install this driver.
    Before you begin with the installation, uninstall the previous driver.

    Secondly: it would be possible that this issue isn't related WLan driver and update the driver wouldn't help you much. In this case you should check the other parameters.
    I recommend you to check the router settings and test different standards WLan (802.11 B / G or N).

    In many cases, the problems of compatibility between the router and wireless network card could lead to similar to your question.
    Of course, you should also go to Device Manager-> card WLan-> properties-> Advanced tab
    and must check if you can switch between the WLan standards singles (802.11 B / G or N)
    Power management also in tab (last tab) you must unselect the option to turn off the device to save power.

    We downloaded and installed the driver from the Toshiba WLAN download site, but it is still not recognized?

  • Satellite Pro c660 does not connect to another wireless after format

    Hey all,.

    I have a Satellite Pro c660 and bought a copy of windows 64 bit with him - the laptop come with many software from toshiba on what I wanted really, I therefore installed windows 64 bit (fitness in the process).

    After the Installation I had some problems connecting to my wireless home (he was missing drivers, but have now install) but finally got it works.

    After having taken it round my friends last night, I could not connect to its wireless - the password has been good and I could see the network, but he just kept constantly defect - its network was on it, because his cell phone he was performing. -The only difference between its network and the spirit (that I can see), it's that she was using the TKIP encryption to connect, while I was using AES (my network card is Atheros). -Even when I tried to configure a network profile and have it automatically connect (using the same information she used, including the TKIP encryption) - it was always not.

    The ideas people? More missing drivers?

    PS - I really don't want all that toshiba nanny software on the laptop.

    Thanks in advance!

    > Any ideas people? More missing drivers?

    If you can see the Wlan network then it means that the WiFi adapter driver is correctly installed and the problem is between the router configuration problems WiFi and wireless network card.

    Are you abele to connect to other networks wireless at home?

    Please disable encryption settings in the Wlan router and try to connect to the Wlan that is unprotected.
    But note; This must be done only for testing purposes!

    You should also check if the MAC address filtering is disabled in the settings of the router.

  • Satellite Pro C660-16F: power adapter that is compatible

    Hi all

    I recently lost the charger of my Toshiba Satellite Pro C660-16F.

    It provides the output DC 19V - 3, 42A

    My father also has a Toshiba Satellite, model A300 1RF

    Supplies of its DC 19V - 4, 74A Chargers

    I don't know if I can use the charger of my father for my computer, like I don't know
    If it is just the current or excessive current it can cause damage.

    Can someone give me the answer to that?, thank you very much in advance!

    Hello

    You can use another adapter 19V.
    The value of the Volt is very important. You can ONLY use the power adapter that supports the 19V
    The ampere is too important, but it may be a little different.

    Your original adapter supports 3.42 Ampère and other 4.74. It's a little higher but not really relevant.

    I tried scanning for new hardware, but nothing was found. I tried to turn the wireless off tension with the function and the keys F8 but not yet showing in Manager devices or any new hardware...

    Any ideas as to what I can try next?

    See you soon,.

    Hello

    It seems that the laptop would support the Wlan Atheros 802.11agn card.
    Usually the Atheros Wlan card must appear in Device Manager as on the menu network cards.
    If it s not appear do not then I recommend that you install the WLAN driver which can be downloaded here:
    http://APS2.toshiba-tro.de/WLAN/?page=downloads

    Choose the Atheros Wireless LAN Adapter Windows 7 (32/64) 9.2.0.419.0 or newer
    I hope this helps to detect the WiFi chip!

  • Satellite Pro C660 - 21(d): question about the partitions on the HARD disk

    Hello

    I just started using my new satellite pro c660 - 21 d

    My office has drive c, d, u, s
    C either windows 7, Vista D
    The drive U is 342 meg in size

    I didn't have the disk in two 230 gig drive so thoughtless narrowed C drive of 70 GB and D drive with 10 gig (it's the primary recovery partition

    I have now two empty partitions of 170 Gig (from c drive)
    and 214 Gig (from d drive)
    But windows will only allow me to add one as a disc of the user
    He says may not have more than 4

    The reason for being there is a partition of Active recovery without letter.

    I can't unshrink drive C or drive D then I went with 170 GB of unused space.

    I guess that a solution would be to lose the data disk 10 gig that contains the recovery software but then I don't have a backup.

    Suggestions as to what I could do to work around this problem.

    I am now under the Create recovery disks (2 of them) so maybe I could remove one of the partitions after.

    I don't know why he answered instead of edition, but if the recovery disc creation complete with no errors, I can remove the hard drive?

    Have you tried to roll back OS to an earlier time using System Restore option?

    By the way: what do you mean with a stopped working?
    This means that some page cannot be opened, or you cannot start IE at all?
    Is there an error message?

  • Satellite Pro C660 - Synaptic Touchpad pinch zoom partially does not work

    Hey there,

    The laptop I have is a satellite pro C660 2I. I've had my laptop for a year (ish) now, and he always had this 'problem '.

    The touchpad has the ability to "pinch" which allows the user to zoom in or out using 2 digits on the touchpad (i.e. move the fingers together to zoom out).

    Unfortunately, the touchpad recognises 2 figures as being present when I use only one finger, but only when I use the right side (or two-thirds of the pad from the right).

    This made me think that maybe he was dirty, greasy etc so I cleaned and nothing has changed. I tried to uninstall the driver, reinstall / update... nothing. The strange thing is that it seems to work for approx. 1 second after I apply pressure to the left hand side in a movement of friction and then use the right side. This leads me to believe that the left side is * being constantly recognized as in use even when it is not *, but I don't know why.

    I do that anyone can recommend?
    Open the laptop and clean it?
    A component failed to be replaced? A software update?

    I'm at my wits end with this laptop, and this is the only problem... is so constant now that the pad is almost unusable (deepened over time, but it wasn't a big deal at first).

    Thanks in advance,
    Griff

    NOTE: If there are all the technical information required, please treat me like a cave man / technological invalid. I am somewhat qualified but I would rather patronisingly simple instructions as sending unnecessary information to those who are trying to help me lose some time.

    Perhaps your question describes isn't related to a dysfunction of the touchpad, but on the fact that the touchpad supports the dual mode functionality.

    + How do I enable or disable the Touchpad double mode +.

    Wireless indicator shows an intense tone, but when I click on connect after that 10 seconds, it says connected failed.

    The network settings are correct (I checked with two other computers that connect without problem), the pc is running x 64 win7. on the toshiba site there is no drivers listed for the local network, I downloaded and installed the drivers from realtek realtek Web site, but no difference.
    Is this a problem with x 64?
    I've tried the recovery disks

    Can anyone help?
    Thank you

    Rob

    On this virtual path, it is not easy to say what the problem is, but there must be a problem with the WLAN settings I guess. What else? Your laptop can detect your router. Question is: what router do you have, what WLAN standard do you use, and you have WIFI password or not.

    Have you tried to reboot your router and check again?
    When you unlock your router you have the same problem?

  • Satellite Pro C660 graphic needs driver upgrade for Adobe Lightroom 6

    I tested 5 Lightroom on my Satellite Pro C660 and it worked fine.

    I decided to do it, and that week Lightroom 6 came out, so I bought Lightroom 6.

    LR6 gets to the start screen, then stops and closes the Windows7.
    I contacted Adobe and they went on my machine and identified the problem as being the graphics card and says I need an update of the driver.

    I've been on the Toshiba site and it says that the latest driver is 8.15.10.2189, which is the one I currently have (and was changed in 2012).

    I've been on the Intel site and their obtrusive says that the machine has a pilot custom then contact Toshiba.
    I looked around the Intel site and tried to install that seem to be plausible drivers, but have not found one that would install.

    My installation includes a monitor LG 22 "connected to the laptop with the spread of the desktop on both screens (laptop and monitor).

    No one knows what would be the upgrade of the driver I need or how can I know?

    James

    The page Intel graphics driver can be used, and you can also download the driver directly from the page.

    This CPU does support your laptop?
    What Intel GPU (Intel HD graphics chipset *) is the support of laptop?

    The Intel download page provides a driver Intel as an exe or zip package
    https://Downloadcenter.Intel.com/

    You need to download and unpack the zip package.
    You will then be able to update the driver in Device Manager, choose the Advanced installation update procedure.

    The keyboard has stopped working, it only works when the keyboard screen is selected as soon as I close the screen keyboard that it stops working. I plugged another keyboard that doesn't work or only works of the mouse and the keyboard on the laptop works ok. I used the Ubuntu live CD, and the keyboard works with it, but not in windows.

    I have restored the laptop to factory settings and also make a clean installation still does not work only when the screen on the keyboard keyboard works. Does anyone have any ideas of what is the problem? It seems that something prevents the loading keyboard driver.

    Supervisor password is very important safety device and a kind of reset of the user is not possible. You can cancel it, but you must know the correct password to confirm that you are the real owner computer laptop.

    Toshiba provider in your country can help you with this. You just approve that you are owner of the laptop, and they can cancel it for you. Of course, you must pay for it.

    As far as I know, there are several techniques for the removal of password and it depends on phone model.

    Contact the closest Toshiba ASP and ask for help.
