My intel pro wireless 3945abg won't work. Install of drivers seems not to happen. Device manager shows wireless not listed. Is there a way to tell if the hardware itself is shot?

I want to downgrade my intel pro/wireless 3945ABG v 12.4.0.21 to v 10.5.1.72 or 10.5.1.75. how to do that?


You will have to remove the driver & softwares from your operating system first.
To remove softwares... Go to Control Panel > Add Remove Softwares > Select Intel Pro/Wireless and choose remove.
To remove drivers... Right click on my computer > Go to Properties > Hardware > Device Manager > Select Wireless Network Adapter > right click on it & select Uninstall
Then Restart your system & begin with the downgrade version of drivers you have.
Enjoy

I can't connect to any wireless networks with my intel 3945abg wireless card. it worked fine yesterday. it shows no networks available. i've reinstalled the driver's, tried a restore thinking it was a bad...


It might sound stupid, but if you have an IBM/Lenovo laptop, it is possible that the antenna is turned off. These laptops have either a software or hardware switch (or both) to turn the antenna off completely.

(Other notebooks have that too, of course...)

Can you confirm that this is not the case?

If you need help on how to check that - please let me know and tell me which computer you have.

Also - make sure that the card is active in your Device Manager.
Again: if you need help how to find that - let me know and we'll figure it out.

Vista Wireless Problem: Intel Pro/Wireless 3945ABG


Hi Pete,

You sound like you know what you're doing, so forgive me if these suggestions seem foolish or patronising..
Does your laptop have a wireless button?

When you go to Internet Options and click the Connections tab, have you checked 'Never Dial a Connection'? This is essential..
I have exactly the same ethernet card and network adaptor, but haven't had any problems, and we have 2 laptops and 2 pc's here all detecting our router okay so..
It's definitely not MAC filtering on the router, as you would still see the network in your list..
I can only suggest uninstalling the Intel Pro Wireless driver and downloading a fresh one from here.
That'll reset default settings at least..
Hope this helps
Let me know how you get on.. If I face this problem I want to know how to fix it too!

If its saying code 10 you just need to update the driver for the device and that error code will be gone....

Code 10, intel pro/wireless


You can try updating the drivers for that wireless adapter. If the same happens, you can try to uninstall it completely then reinstall it with the updated drivers.

You can also try to install it on a different slot or a different laptop to test the connection.

If you have other problems, go ahead and press the ask button and i'll answer it for you.

Device could not be started


This sound like its a bios problem, check in the bios F2 or Del on boot up and look in the menu for your internal wireless adapter as it may have been dissabled. This is the only way your notebook can possibly have to keep installing it, as the device is there but not being recognised next time you boot, check to see if the cmos time is correct, as other things may be incorrect. The only other thing is that the card driver is not correctly loaded as when the pc boots it should find the hardware then install the driver for the wireless reciever straight away, if its asking for a driver then the driver has not been registered in windows and cannot be found.
