Satellite A100-784 - Intel PRO Wireless 3945ABG off randomly


I have Toshiba Satellite A100-784 with Intel PRO Wireless 3945ABG wireless adapter.
Today I was working with my friend on some project connected on his wifi sharing internet connection on Toshiba Satellite A100-510.
After a while I lose the internet connection and I see that this blue icon is no longer in the test system.

I try to use Toshiba ConfigFree but it was impossible to open, so I try to open the network connection of the control panel and after a period of time the network connection has been accessible and I saw that this network adapter is disabled. I try to activate three times but nothing.

After rebooting, everything was ok and wireless adapter is turned on and ready to use for the next 10 or 15 minutes.
First disable comes after two hours. I use Windows XP SP 2.

The problem is that I have to restart my computer everytime where I lose internet connection (WiFi is turned off automatically).
Everything is blocked its very hard to access the settings of network or toshiba configfree

Thank you


Try this:

Update the BIOS of the laptop
Update driver Intel Wireless LAN
Use static IP addresses, instead of dynamic (DHCP)
Temporarily disable your firewall software
Update the Firmware on your Access Point

    I can't use my WiFi connection and currently think that maybe it's to do with the driver for my Intel PRO/Wireless 3945ABG Network Connection.
    I was in the system and tried to update the drivers, but it does not work and have also tried to download various updates without success.

    Please can you advise

  • Intermittently lose connection WiFi. XP Pro, Intel Pro/Wireless 3945ABG

    I recently recovered from a nasty virus and my computer seems back to normal except an annoying problem. Periodically, I lose my wireless connection. It happens on multiple networks, so I know it's the computer. I updated my drivers (all who were on the Dell support site specific for my service tag) and still not fixed. I used to be forced to restart, but now (after the driver update), I can use the Device Manager to disable, and then enable the wireless adapter and the connection returns every time... but its obviously annoying.

    Any suggestions would be helpful. I have a Dell Latitude D630 running XP Pro. The
    card is an Intel PRO/Wireless 3945ABG. Thanks in advance.

    You may not say anything on the power saving mode, but the link you posted has done. None of these things worked anyway.

    However, I found a solution that others may find useful. Apparently the Dell Web site is not exhaustive with regard to the pilots. I found a update for my driver wireless on a third party site,

    After the update, the problem has been resolved. DriverMax is an application that is free to download and much appreciated on

    Free version allows only download driver per day, so be sure to choose carefully.

    Lesson learned: sites Web of manufacturers is not always the best place to find updates driver

  • Satellite M60 with Intel PRO Wireless 2200BG - no stable connection possible

    Hi, it is not possible to obtain a good connection with the Intel card and the latest driver from the homepage of Intel, even with all the other drivers, it is not possible. The Forums are filled with problems connecting with this card! I need a solution. Game online (World of Warcraft) is not possible because the ping (Laency) is 5000ms, and server kicks all the time, with other laptops without problems.

    When I turn off energy-driver settings, it gets easier, but still terrible connection. Intel or Toshiba do something! Tried already weeks solve this problem with all the possible drivers and settings in Windows XP SP2.
    Other users of the Intel card have the same problems.

    Hello, Robert

    You are absolutely right on this Intel WLAN card. I checked some books forum and many other users have similar problems with different laptops (different producers but the same map).

    I noticed that this card make a trouble with different routers. A friend of mine has Satellite M40 with the same card and has no problem with the Netgear router, but with my Belkin one drops the connection permanently. We did the test with US Robotics router and the connection was not good enough.

    Unfortunately, there is nothing to see. The only solution is to swap the WLAN card and built the other one (Agere or Toshiba one).

    Good luck!

  • Intel Pro/Wireless 3945ABG cannot load the driver

    Wireless worked fine since I bought this laptop

    Now it has stopped working and has a yellow exclamation mark in Device Manager - it says "this device does not work properly because Windows cannot load the drivers required for this device. (Code 31) »

    So I uninstalled the device and check the box that says "Remove the driver for this device", then reinstalled the latest version of the driver on the Toshiba site

    Windows Vista detects new hardware and install the driver, but fails with 'Windows found driver software for your device but encountered an error trying to install it. The system cannot find the file specified. "

    All ideas

    Remove the wireless network adapter in the device, download manager driver the latest from Intel page and repeat the procedure of installation of the driver.

    Good luck

  • Intel PRO/Wireless 3945ABG slow wireless

    I reformatted my laptop on a wek ago, and since then, I've noticed that my wireless works more slowly than usual.

    Before he was reformatted my download speed is about 240KB, but now it's about 160KB download. It is not the source of the download as my old Toshiba with an external wifi adapter gets about 240KB download the same file.

    I've updated the drivers to those most recent outside, but it has not changed a thing.

    I don't know what I can do and any help will be appreciated.



    Your Intel Wireless card supports three different modes of WLan: A, B and G
    These three different modes that also supports different speeds.
    In my opinion your use a slow or well the server mode where you download files of does not support a faster speed.

    All WLan settings, you should find in the WLan card properties. He just go to Device Manager, select WLan CAD and click Properties.
    On the Advanced tab, you'll find plenty of options, and there you can choose A, B or G mode.
    Additional I recommend you disable the saving on this card.

  • Satellite A200 - Intel Pro Wireless 3945 fall

    I have a problem with my laptop Satellite A200 (with Vista Home Premium 32 bit) where the Intel Pro Wireless connection keeps itself turning off after several minutes or several hours of use.

    In network connections, the wireless connection is shown as people with reduced mobility. When I try to enable it, it will say something like "Enable already ongoing attempt". And he's never coming back. However, wireless orange light is always on the cell phone all the time. The only way to reactivate the wireless connection, is to restart the system.

    I know this is a very common problem, I see the same problem among other threads on this forum.

    After a short search on Google, and I see that many other people have the same problem too, particularly with Dell laptops. Forum sites there 2 in particular, that have the most information on this topic, I found:

    These are the things that I tried to resolve this problem:
    (I got all the drivers from the site, that I got this laptop from NZ and the specific laptop model number is PSAFCA A200)

    -Updated the BIOS with the latest version.
    In fact, I think that updated the BIOS could be the cause of this problem wireless, or in part. Because a few months back, the laptop kept cutting itself no reason apparent, perhaps once or twice a week. So I've updated the BIOS, which actually fixed the random stops, but since then, I've known this wireless problem. Coincidence maybe.

    -Upgrade to the latest driver for the wireless network.
    I tried a various number of drivers. Later off the coast of,, None of them have worked.
    For the moment, I use the older driver comes preinstalled with Vista.
    Intel Pro wireless 3945ABG (Microsoft) was sometimes since 2006. And surprisingly, this one works best. Drop-outs are not as frequent as more recent drivers, but the problem still happens.
    With this new drivers (dated from 2007), I find that it turns off several times a day. Once or twice an hour.
    With the former, once every two hours.
    That's what I feel, it is probably coincidence.

    -Update of Windows Vista with service pack 1.

    -Updated the firmware on my router. It is a DLink G604T. However, I doubt that it is one router problem, my other laptop running fine without any abandonment wireless.

    -Power WLAN disabled economic option.
    Under power settings, select the setting of maximum performance.

    -Set lowest roaming aggressiveness, even tried with highest.

    -On the "Power Management" tab in the properties for Intel Pro Wireless 3945ABG Network connection, tried to activate and deactivate the option "allow the computer to turn off this device to save power".

    -Done a full virus/spyware scan.

    -Uninstalled the software Toshiba Wireless Zero Configuration.

    I think I've tried just about everything that I can, so I'm here pretty much as a last resort.
    I hope someone can help me solve this problem.
    It was so annoying since many months now! It's not fun to have to restart the laptop all the time.

    Thank you.

    I see that you have tired most of the things that I would say too
    You said that WLan works better using the old driver Wlan MS if it s really a WLan driver problem

    But what said
    I searched a bit in the MS knowledge base and found this article:
    + Several problems occur on a Windows Vista-based computer when you work in a wireless network environment.; EN-US; 932063

    Check it out.

    But a friend of mine had a similar problem of Wlan and nothing helped, he did a update BIOS, set the Wlan driver, etc.. nothing!

    Finlay, he changed WiFi channels.
    He chose the other channel on the router and wireless network and since then the Wlan card works well...

    Maybe it s worth a try!

  • Satellite A100 - Upgrade Intel for 5300AGN Intel 3945ABG WIFI card

    Hi all

    I own a satellite A100-383 PSAARE. I want to upgrade the wifi card, like the one it is installed right now (PRO/Wireless 3945ABG), does not all the speed, the line can achieve (100 MB to the bottom). Anyone know if the map intel 5300 AGN is compatible with my laptop. If not I would appreciate a lot of suggestions.

    Thank you

    Don t think that someone can give you an appropriate response since the compatibility depends on the BIOS
    If the BIOS would be compatible with the new WLan card, then you can use it for you

    The point is that motherboards is able to manage the cards WLan miniPCI module is just plugged the miniPCI slot and its removable
    So there is just one question about BIOS support and I m afraid you will need to test this at your peril

  • Satellite A100 - 784 PSAANE - screen turns off automatically

    Hi friends,

    I have a Toshiba Satellite A100 - 784 PSAANE with windows visa Home Basic edition.
    Now for 15-20 days I am facing a strange problem. The screen of the laptop emits a sometimes (not necessarily every time) and then when the frequency increases the display turns off automatically!
    Then I must Hibernate or he put laptop to sleep to find again the screen... Seriously, I don't understand the problem.

    Please help me.
    Thanks in advance

    Hi Julie,.

    It sounds as if something is harming your graphics driver causing the display to turn off. If the problem occurs only when you use certain applications or only started after installing a new application you may need to restore your system to a restore point before new applications have been installed. As a test, you can try to start your system in safe mode and see if the problem persists.

    I also recommend that you re-install your graphics drivers to see if it improves the problem.

    Other possibilities are that your graphics chip is a failure or overheating causing this problem in which case you have to return your laptop to a Service approved for the additional diagnostic agent.

    My last thought is that you may have a problem with the inverter FL (the component that provides the lighting of your LCD screen). Check, when the screen turns off, if you can still see a residual image on the screen. If yes then the FL inverter is definitely at fault.

    Kind regards

  • Should I update Intel INF Utility on Satellite A100-784

    Hi guys,.

    I want to ask you. I started using the AdvancedCare system and the menu "update Driver" it showed me that I should download Intel INF Update Utility (

    But I'm confused now if I have to install it when Windows Update never showed me this update possible.

    Is my laptop Toshiba A100 - 784 PSAANE and I use Windows Vista Ultimate 32-bit (No OEM base Vist I got when I bought this laptop).

    Thanks for your advice.



    Satellite A100 - 784 PSAANE works without problem?
    If Yes, then why you want to update anything?

    I have followed this recommendation; never change a running system.

    And in addition only a hint: use always the Toshiba page tools and drivers. Don t install any driver tool from 3rd party page if it of not really necessary.

    Good bye

    Hallo Simon

    One thing is strange to me. You ordered the WLAN card update? Technicians have tested the functionality of WLAN card? Did you send your laptop to the Toshiba authorized service partner?

    If the map is compatible and correctly installed, you should be able to activate the card by using the WLAN switch. Please try to reinstall the driver. You can find it on

    Have you checked the State in Device Manager? There is a yellow question mark? If there is no problem with the right mouse button you can activate it.

    If there is no green light try anyway to make connection and check the functionality of the wireless card. Perhaps is the lack of green light.
