Driver Wireless 802.11n Windows 7

[Rode Neagle]

Ihave an old Acer Aspire (32-bit) laptop with an Intel PRO/Wireless 3945ABG adapter from 2008. Having just forced it to upgrade from Windows 7 to Windows 10, I noticed straight away that the wireless was not working (maybe that's why I didn't ever see the Microsoft upgrade option).

I downloaded the -PROSet-Wireless-Software-and-Drivers-for-IT-Admins?httpDown= _18.11.0_De132.zip Wireless_18.11.0_De132.zip from this page: then ran the DPInst32.exe file inside the .zip. Nothing much seemed to happen, but on checking Device Manager, the system indicated that the driver is installed but "the device failed to start". I disabled the device, then enabled it - still nothing... getting bored I decided to reboot the machine and start looking for my USB adapter...

Anyway it rebooted, connected to my network and is running perfectly. Not bad for an old Vista machine. Maybe the driver was installed all along and all I needed to do was reboot the machine in the first place. I don't know, drivers aren't really my thing! I thought I'd post this just in case there are other people with similar antique machines lying around.

I've tried the solution listed above, but it hasn't made a difference. I realise that this adapter is now unsupported, but I wondered if you had any advice as to how to fix this issue, maybe a replacement driver or something?

Since the Intel PRO/Wireless 3945ABG Network Connection is not supported by Microsoft Windows* 10, we would not expect it to work properly. Intel does not provide drivers for this configuration, and we are not aware of possible workarounds.

If Windows* is not able to locate a driver from Microsoft* using Windows* Updates, then we would advise you to check with the Computer Manufacturer Support to confirm if your system is meant to be used with Windows* 10.

No wifi after upgrading from Win 7 Ultimate to Win 10 and Device Manager displayed the following message in the Device Properties dialog box, on the General tab, in the Device Status text box: "This device cannot find enough free resources that it can use. If you want to use this device, you will need to disable one of the other devices on this system. (Code 12)".

The following actions rectified the problem and might be worth a try for other people. One thing it demonstrates is that the Intel legacy wifi driver (Intel(R) PRO/Wireless 3945ABG Network Connection) works in Win 10 although no longer supported by Intel or Microsoft. In my case it involved disabling PCMCIA drivers (I do not use the PCMCIA card reader but there could be other options not tested). It was tested and worked in a Fujitsu Tablet ST5112 with a Centrino processor, running Win 10 Pro, 32bit as follows:

I probably found the solution for the Wireless disconnect after waking up from sleep mode with the Intel 3945ABG. I simply disabled the "Computer can disable the device to save energy" option. The option can be found in the Network Adapter configuration at configure - Energy saving options. As I have a German OS, the english terms might be different, but you will get the respective options by its meaning :-).

I found that disabling the PCMCIA Controller on my Fujitsu Lifebook N Series N6410 is what worked for me. I never use, nor have never used, the PCMCIA ports. I know this is an older thread but thought I would put it out there for people to see.

I'm sure that Intel will not mind me mentioning that the simplest solution to the Acer Aspire 5920 and Windows 10 wifi compatibility issue is to replace the Intel mini-PCIe adapter/card with the equivalent Broadcom card (the ethernet driver in this PC is already Broadcom). The equivalent wifi card is the BCM94311MCG at the dizzy cost of 4.00 from eBay. Very easy to fit (see YouTube) and installs perfectly and quickly DURING AND AFTER boot (so give it a chance) and assuming you have your ethernet cable fitted and working.

Another simple solution I was using was to just buy a tiny USB wireless dongle for 3 bucks from ebay, that did the trick too., but it's nice not to have any unnecessary peripherals hanging on the side.

I Have an Asrock 390m-itx/ac mobo. Everything was fine, but then these automatic updates were pushed to my pc, and now the intel wireless bluetooth is screwed up. You can see the little usb icon in the systray toggling on/off continuously, and if you look in device manager, the icon is constantly disappearing and reappearing, and you can hear the windows new connection sound effect constantly going off. Intolerable.

I should note that when I see intel wireless in my device manager, i can uninstall, but there is no checkbox to delete files as well. This does exist on Intel Bluetooth. When I reboot, the Intel Wireless driver is already reinstalled.

I had recently updated Intel BT drivers and after that no BT device would connect to my desktop PC anymore. The BT on/off toggle had disappeared form that right-side panel accessible from the taskbar. When I opened Device Manager, the entire tree of devices would keep on refreshing every 2 seconds, until I manually disabled the Intel BT adapter (which was being continuously reset or something). I tried all manners of drive removal/upgrade/downgrade to no avail. Of course I tried rebooting the computer and even messed a bit with BIOS configs for nothing.

Yep. Like many others, I created an account to say thank you- roughly four years after this thread was created. The solution is still relevant, and it's far and away much easier and less time consuming than any of the other "solutions" I tried.

Edit: It might be important to add that different machines might require a longer or shorter interruption in the power supply for this to work. I've seen one person in this thread who unplugged their machine for 15 minutes, but I only unplugged mine for about 30 seconds.

After the last update for Windows 11 insider (Home). The driver for the wireless card stopped working. There is already a guide on the issue on Intel's boards, but it is not working either. So i think the issue is with the Windows.

I managed to bring my Killer wireless network adapter back - after wasted a whole morning. Windows updated overnight and I lost the card after that. This was the error I saw in Event Viewer:

@OussD After a lot of research, the problem is usually solved by resetting the bios to default, mainly on dell laptops. The problem is caused after doing bios update or installing windows 11.

Also don't forget to install the updated drivers.

@ballon999 This is not working on my Surface Pro 7. I've tried uninstalling and removing the driver completely several times and each time on the restart it automatically comes back (even when I'm not connected to the internet). I had Windows 11 and reverted back to Windows 10 and still not right.

I had a similar issue when I got my first wifi 6 networking card. My solution was to turn off automatic band selection in the wifi router settings. Apparently the network card couldn't handle when the band changed (something that the router did seemingly randomly), and so the network card errored out and stopped working until it was reset. However, after I turned off automatic band selection there hasn't been another issue, with that machine.

Everyone, try removing the driver then shutting down the OS, not reset/reboot. I've been fighting this for 2 days straight and even after a complete OS reinstall/downgrade from 11 to 10 the problem is still there. Immediately after the reinstall the wifi adapter worked, but after a few reboots it went back to the same issues/events in the system log. Then I tried removing the driver and shutting down completely before powering back on and the wifi is now working. For how long who knows, but give this a shot if you are struggling.

I am having problems with Bluetooth on my pc not even being visible to turn off and on, it's not showing up in the device manager but if I go to & apps and features it shows there is a driver installed but nothing showing up. When I originally had my PC running on windows 11 my bluetooth was there and working since doing updates that DST has told me to do I performed the latest for my bluetooth to disappear completely.

I have a Intel(R) Wi-Fi 6E AX210 160MHz driver installed for my wireless however no matter what combination I have tried whether it was a fresh install of the drivers (removing them, restarting computer with no internet connection and then installing the drivers manually) which failed and the DST is showing my device drivers as up to date. I have also tried rolling back the driver which did not work and I really do not want to have to fresh rebuild my entire operating system already but I am getting to a loss on how to resolve this.

In this case, we would recommend first checking the BIOS settings in case there is an option related to the Bluetooth that might be disabled or Off. For this task, we recommend reviewing your computer's User Manual or contacting ASUS* Support for proper assistance.

If such as Bluetooth setting is Enabled/On, we recommend trying a clean installation of both Bluetooth and Wireless drivers. The driver or software for your Intel component might have been changed or replaced by the computer manufacturer, therefore, we recommend trying this first with the customized drivers from Asus* website.
