• Intel PRO/Wireless 3945ABG Network Connection problem under Win XP (Latitude D430 computer laptop)

  I use Latitude D430 Laptop & Windows XP. Initially, it is ok, but after some time I have a connection problem. I have run the diagnostics & "Radio Test" failed. Any idea about this problem? The problem is solved only when I restart my computer. I think the Win XP driver problem because I don't have this problem when I use Win Vista. Everyone knows it needs to solve this problem?

• 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, Drivermax.com

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

  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 A100-784 - Intel PRO Wireless 3945ABG off randomly

  Hello

  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

• 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 11.5.0.32.

  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

  Hello
  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.

  Hello

  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

  Hello
  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:

  http://www.vistaforums.com/Forum/Topic4198-45-1.aspx
  http://thevistaforums.com/index.php?showtopic=9834

  These are the things that I tried to resolve this problem:
  (I got all the drivers from the site http://www.toshiba.co.nz, 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 http://www.toshiba.co.nz, http://aps2.toshiba-tro.de/wlan/, http://www.intel.com. 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.
  http://support.Microsoft.com/default.aspx?scid=KB; 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!

• How to enable Intel Pro Wireless 2200 satellite A30-514

  Simon Wakeford

  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 http://aps2.toshiba-tro.de/wlan/

  One last thing: is your laptop preinstalled with Toshiba recovery image?

• R51 Intel PRO/Wireless NIC 2200BG will not keep Radio Active

  Trying to activate an Intel PRO/Wireless 2200BG NIC I have it configured and connected. After a reboot or power down/up the NIC comes up with the 'device wireless off. I see this when I go to Device Manager and select properties for this network controller. And then clicking the Advanced tab, I see "(radio off) wireless device" with a check box indicating that it is indeed 'off '. I uncheck this box and the message "this setting only take effect if the power button on the adapter is turned." Then clicking OK two times the changes are applied and the NIC rises and works until the process of booting from the network. I tried updating the driver, but the update process tells me that I'm late a (8.0.12.20000) installed. I searched this forum but have not seen all the patches. Anyone have any ideas? TIA for any help.

  Bob Helms

  The answer is;

  1 uninstall the wireless network card.

  2 re-boot and let XP find the wireless network card.

  3. manually configure the wireless NETWORK adapter to work with your wireless router.

  If you do not manually turn off the radio it will remain turned on and configured after a re-boot.

  Thanks for your replies.

  Hello

  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.
