Hello Tayyabses,

Please reply with a little more clarification about the problem. If possible, please add an screenshot of the “Device Manager” showing the Broadcom Wireless card. Also, add the Device Instance ID of the device with the exclamation mark. To get the Device Instance ID: 

1. Press the Windows + R key on the keyboard to launch the “Run” dialog box.
2. Type “devmgmt.msc” and hit “Enter”.
3. “Device Manager” window will open.
4. Open Network Adapters and right click Broadcom Wireless card
5. Select Properties.
6. Click the “Details” tab.
7. Select Device Instance Path or Device Instance Id (whichever is available for your version of Windows) from the drop down box. The first part of the Value identifies the drive type followed by a long series of underscores, and then the firmware version number. The rest of Value is not needed. See the sample image below (this is for Optical Drive, it may be different for your device), the first part of the value shown identifies the drive type as "IDE\CDROMHL_BDDVDRW_GBC-H20L", followed by the firmware version number of 1.B8.
   
   
   
   Write the version number down.
   
   
   

In your reply please add the Device Instance Path or Device Instance Id so that I can research on the issue.

Hello Tayyabses,

Thank you for the update. I am really glad to know that the issue was fixed. Please feel free to write back to the forum if you need any further help.

Hey all, firstly sorry I know this is a very old post to post a solution for, but any ways I know many are like me who desperately need drivers for this Broadcom BCM94312MCG Wireless Internal Adapter commonly used in various laptops / notebooks of many makes. I had this one in my Acer Aspire 4720Z Laptop which originally was not from Acer (factory default hardware) so naturally didn't have the drivers for it. I once gave this out of warranty laptop for servicing at a un-authorized service centre & there the hardware technician for some reason swapped my original Broadcom WiFi adapter (model no. not known) with this BCM94312MCG one (which unfortunately I came to know much later). When I once tried to connect this laptop wirelessly to my cousin's WiFi, I found that the Wireless LAN connection or adapter was not visible under Network Adapters & even under device manager it had the yellow mark  & properties said - cannot start this device 'Error 10'. I Googled a lot & then finally decided to give it a try by opening the Laptop's backside Wireless adapter enclosed panel to revel the actual wireless adapter & found this model no. i.e. BCM94312MCG printed on it. I then Googled for the appropriate drivers & finally found this link to download the driver file that actually worked for my Laptop's now installed wireless adapter. 

So here is the download link / URL at current time -

Hope this helps all the needy ones like me. Sorry if I am posting it here and that too this late.
