The driver Wlan don't work?

I use ideapad s100...
What happened is that I had some problem black screen in startup which lead to the computer seeking redress of the system for which I did, but after that, my computer doesn't detect any wireless network. When I download the latest driver from lenovo for which I thought that the problem is the driver, it was installed successfully but the issue has not been resolved and also, he did not appear in the Device Manager. I do the system restore, but the problem is still there and it also restores my previous black screen problem ... Cable Internet works with the laptop and only wifi is the problem.
When I run the OS of lenovo QuickStart, the wifi works there... so I was wondering who has the problem, the Windows 7 operating system?
also, when I press the Fn + F5 key while in the windows 7 OS, which will show only the bluetooth wireless adapters is where before, it shows both bluetooth and wifi...
I'm planning to factory restore this laptop so I don't think a solution, but I don't know if this will solve the problem because the system restore did not help at all.

Any suggestions? Thanks in advance

Try to update the Bios and the energy of Lenovo software of management. Since you are able to use the wlan in quick start it means wlan card is ok. If this does not correct, then you can do a factory using OKR reset

Hope this Helps
See you soon!

  • Satellite Pro A200 PSAE1E: Can't get the shortcut keys don't work on Win XP

    Hello

    I have a Satellite Pro A200 PSAE1E that came with Vista on it, I reinstalled Win XP Pro installed with relevant drivers download Toshiba page but cannot get working shortcut keys.

    I installed the controls and the driver, but that doesn't seem to work. Saw an ad on "common module" somewhere, but can't seem to find any links to download on the download page.

    Can anyone help?

    Thank you very much

    Iain

    The control utility and driver controls allow you to customize and TOSHIBA special button preset settings. But it is not a FN keys!

    You must install the Hotkey utility if you want to use the FN keys.

    Another tip:
    It is important that all Toshiba drivers and utilities are installed in the correct order.
    On the Toshiba driver page, you will find a txt file called installation instructions.
    Please install all drivers and tools in the order mentioned in this instruction!

    Greetings

  • Equium A210 - 17I PSAFJE - Lan and Wlan don't work running Windows XP

    Hello

    I recently received this A210-17I (PSAFJE) for Christmas, but to my dismay, it was not compatible with most of my computer games, I decided to downgrade to Windows XP, after reading about how I could do this, I decided to do it myself.

    So far everything works great, with the exception of 2 factors.
    The controller Ethernet and RTL8187B_WLAN_Adaptor, which appear as unknown devices in Device Manager.

    I installed ALL the drivers for download from Toshiba for this specific model page and I have operational including graphics and sound rest.

    The WLAN adapter is strange for me, I downloaded this driver: http://www.realtek.com.tw/downloads/downloadsView.aspx?Langid=1&PNid=1&PFid=1&Level=6& Conn = 5 & DownTypeID = 3 & GetDown = false & downloads = true (the bottom one for Windows) and it seemed to install OK with the provided setup.exe. But the device is still unknown, and it will not install if the folder "Update Driver".

    I have no idea what to do about the Ethernet controller :(

    Thanks for reading.

    * EDIT: Fixed; D *.

    Looks like you have already decided to install a compatible driver of LAN and WLan.
    Am I wrong?

    It of good to know that the problem is solved

  • Satellite Pro L20 PSL25E - where can I find the driver WLan?

    Hello

    I have a Toshiba Satellite Pro L20 - PSL25E 00G019GR and I am trying to install the wireless card.
    Where can I get the software/driver?
    I can't find these (for Windows XP) in the download area.

    The wireless device is turned on, but I don't see the icon in the network environment.
    So, what should I do?

    Thanks for your help.

    Michael

    > The wireless device is turned on, but I don't see the icon in the network environment.
    Are you sure that the laptop is equipped with wireless network card?

    AFAIK the L20 Pro Sam is an older model laptop and L20 not all were equipped with internal WLan module even if the WLan switch is available.

    You should check if the wireless network adapter is listed in the device under network adapters Manager.

  • 3000 N200-0769-ENG via the Touchpad scrolling don't work

    I have a new lenovo 3000 N200 0769-ENG (vista Home premium sp1) and have problems with the touchpad.

    The touchpad works with the lenovo driver, but its recognized as one mouse only. So I don't have the ability to set the vertical/horizontal scrolling, the only available option is to configure the buttons.  And the touchpad no longer works if I tried the new driver for the synaptics site. The bios that is installed is October, I don't remember the name but I think than his 68ET37WW.

    Is it possible to scroll with the toucpad at all? or is it a driver problem?

    Concerning

    Lars

    Just want to connect and update this post.

    Today, I had options for scrolling and advanced working for the first time!

    I installed the latest driver that I could find. (synaptics_v13.1.3.0) and low and here this worked!.

    I tried the latest drivers before with xp, vista and win7 without luck, so I had given up to make it work.

    So, Lenovo, thank you's for nothing!

  • Since Firefox 13.0.1 my scrolling speed is very slow and lazy. Disabled all the plugins still don't work. Any difficulty? I HATE IT!

    As soon as Firefox when through it's automatic 'upgrade' the scrolling action became very slow and lazy. I tried all this suggested (disable plug-ins, re-installing Firefox, restart the computer, etc.), but I still can't get back to the way it was. Is there a fix, or how can I re - install the older version that worked so well? I HATE THIS!

    Hello mjg263, firefox 13 introduced a scroll smoothly by default - it might not work well on older hardware.

    Please, try to update your video driver or if this does not improve the case you can disable scrolling smoothly in firefox/tools > options > advanced > general.

  • Satellite Pro P300-19 q WLan don't work in Win XP & keyboard problem

    I just took delivery of one P300 19 q which seems fine other than...

    1. the Wireless does not work

    2. the keyboard in my opinion is c * p

    I removed Vista, I use the laptop for XP and music is much better (not sure if this is related) but I can't get WiFi to work.
    I spent hours on the phone with Tiscali clean technology and directs the laptops with no joy.

    Any ideas?

    Also, I'm not at all happy with the keyboard. The high-lift device together the keyboard keys to the left and right seem very strong, but everything else seem like they should be on a toy. Its this really how they should be?

    I would appreciate a quick response because I'm undecided if I should get a refund or a replacement.

    Thank you very much

    Hello

    As far as I know the laptop uses an Intel WLan card. Right?
    In this case you must update the BIOS to version 3.00 or later.

    With respect to the keyboard.
    I put t know what you mean exactly by rest seem like they should be on a toy, but it s a black buttons keyboard brilliant 105 communes like these keyboards of laptop:
    http://www.Darfon.com.tw/English/HID_NBkb.asp

    You will find these keyboards on different laptops from different manufacturers.

    But if you think that there is a problem of keyboard and that there is something wrong then contact ASP in your country for a control keyboard (just to be 100% sure)

    See you soon

  • Internet Explorer hang ups and the desktop icons don't work

    I have a 32-bit Vista, which has worked perfectly for almost 4 years until yesterday. Freeze the icons on my desktop and internet explore cannot open any other web site, after having opened the first web site. Once you close the web site, and then try another icons do not work for short cuts. The taskbar remains functional. I have to go into the Task Manager to close Explorer which rest spinning means that it cannot open. I tried a system restore to two days ago and he said there is a mistake, and he couldn't change my settings. Then I went to windows defender under programs to view current programs and I found several programs window internet explorer running even though in Task Manager, they were removed. Once I erased these stars, the icons would work, but only for the first attempt. Then I went to the Windows Defender and 2-3 lines of windows internet explorer is numbered. Why is this happening? For every time that you access internet prgrams multiple of the same are running and then hang up the entire internet and shortcuts icon freezing. Help, please.

    Thank you

    Success!  All I had to do was reset internet explore windows. Fortunately, this did not clear all of my passwords or settings which I expected. The only change I noticed was the size of the screen. I had to change to fill the computer screen. I don't have to do a system restore.

    Thank you and thanks for your replies to bab66.

  • A real OS Windows 7 on the drive usable in another working laptop during repairs?

    I was asleep for the use of my computer and knocked over a can of soda through her, and she trotted away for more than 6 hours, until what I woke.

    I first noticed the image on my screen flickered whenever I hit the keyboard, it took 10 minutes to find out why.  The top surface of my computer and the keyboard are not sticky, and it was not much of a wet place.  But when I moved the computer, and several ounces of soda dripped out in cd/dvd charger, I realized what had happened.

    I managed to all close and remove power and the battery without seeing any sign of damage electronic or digital, but it will be some time before I lucky will use again.

    I can't afford to have someone else fix it, but I am technically qualified to disassemble, clean and reassemble.  I already know the hard disk and the operating system have survived, because I moved my laptop in another drive that I borrowed from my brother, and I use it to write this discussion.

    I need most of what is on this drive to use daily in my business, I am familiar with how it works, and I do NOT want to learn how to use another operating system right now.

    I've damaged my laptop, but it should be used every day.  I thought that since I was the legal owner of the operating system under license from my computer, I should be able to move my hard drive intact a laptop different, until repairs are made.

    It seems not simple, however, because I need some drivers, but Windows messages continually interrupt everything I do.

    Is it possible that I can use my own hard drive and operating system and still no drivers, I need for this computer, and then switch back to my own computer in a few days?

    Well, if it's a license of Windows 7 purchased in retail store you purchased and installed yourself, it should not be a question of transfer to another computer and use it as long as you install the drivers appropriate for this configuration. If it is preinstalled on the other system, you move well, then you will not be able to transfer bee successfully since its related to the old system, meaning that it will not be activated.

    Otherwise, if it is a retail license and you are able to clean and sort the system that you upload, you can always move it when you are ready. Since his work on the current configuration, I use the opportunity to back up all your important data.

  • Dropped my Satellite M30X - now sound & WLan don't work

    I dropped my Satellite M30X on the carpet, and now the WiFi and sound no longer work. (The wireless light is not turn on when I turn on the switch).

    Is this a fixable problem or I have to buy a new computer? Please let me know.

    -Yvette

    > Is this a fixable problem or I have to buy a new computer?
    Hmm. Maybe you won't need new computer, but a new hardware component.

    I think you will understand that it is not easy to say what might be broken fact is that this must be a hardware problem. There may be a part lost contacts and it can be fixed very easily?  :|
    I think that its worth to contact an ASP (certified partner) or a technician from portable to downtown and in what concerns control of the laptop.

    I remember that my brother fell a laptop and it couldn't boot t upward.
    Finally the technician discovered that the module ROM jumped. It is easy to fix
