T420s (4170-CTO) Windows unable to recognize network controller

2013-07-20, 20:28 PM

I have been running ubuntu on my T420s for about 2 years now.  Needed a Windows box to work from home so I installed Windows 7 Home Premium - Service Pack 1 on it.  Installation went smooth but Windows did not recognize my wireless card, preventing me from connecting to the internet to download and install the rest of my drivers.  I tried to manually install the Intel Wireless Lan (bg, abg, abgn) for Windows (64-bit) Centrino Advanced-N 6205 which is what I thought was installed on my machine to no avail.

 

Has anyone expierenced this problem before that could point me in the right direction?

 

Thanks!

Solved! See the solution

Hi, xm

 

If you navigate to Control Panel ► Device Manager, what devices do you see underneath the Network adapters tree? Also, just to make sure, I would recommend navigating into the BIOS to Securiity ► I/O Port Access and making sure the wireless LAN is Enabled.

 

Thanks in advance,

Adam

Hey thanks for the response Adam,

 

I do not have a Network Adapter tree in the Device Manager.  Network Controller is listed under the Other Devices tree, along with Ethernet Controller, PCI Simple Communications Controller and a few others.

 

The properties for the Network Controller produces the following information:

 

Device type: Other devices

Manufacturer: Unknown

Location: PCI bus 3, device 0, function 0

 

Hope this provides something useful, please let me know if you need any additional information.  Thanks!

Hi again, xm

 

Thank you for the information. If you have access to an Ethernet network connection, then I would recommend downloading this driver here first. This should allow you to use a wired connection, through which you can install Windows updates and Lenovo updates, which should install the proper drivers for your machine, thus allowing you to use wireless connectivity. 

 

Hope it helps,

Adam
