G510 Windows 7 WLAN driver doesn't work

2014-03-07, 18:33 PM

My G510 came with Windows 8.1 pre-installed. I didn't want that, so I installed Windows 7 instead. After that, I downloaded this driver (WLAN Driver (Atheros, Broadcom, Realtek) for Windows 7 (32-bit, 64-bit) - Lenovo G410, G510) using a different computer. I copied the driver to a USB thumb drive. Then I installed the driver on the G510.

 

The driver installed without any errors. However, I still can't enable the wireless adapter. Device manager shows missing drivers for several components (as expected) under "Other devices" but I am not sure which one is the wireless adapter:

 

  • BCM43142A0 (I believe this is the bluetooth adapter)
  • Ethernet Controller
  • Network Controller
  • PCI Simple Communications Controller
  • SM Bus Controller
  • Universal Serial Bus (USB) Controller
  • Unknown device
  • USB2.0-CRW


Control Panel > Network and Internet > Network Connections shows no network adapters at all, but Control Panel > Programs > Programs and Features shows Lenovo_Wireless_Driver is installed.

 

When the installer runs, it copies the files from the "C:\drivers\WLAN Driver (Atheros, Broadcom, Realtek)\Broadcom\6.30.233.75\Driver\Win8" directory to "C:\Program Files (x86)\Lenovo\Lenovo_Wireless_Driver\Win8" directory. I believe the problem may be that this is in fact a driver for Windows 8 and not for Windows 7 as indicated.

 

I thought at first I may have just downloaded the wrong driver (I was careful to select the right one), but after downloading it again, I confirmed that I have the correct installer with the file name wlan125w7u1.exe.

 

I've tried re-installing the driver several times as an administrator, rebooting before and after each install. I've also tried Fn+F5 and Fn+F7, which does nothing.

 

Edit: I almost forgot the best part. I called Lenovo technical support last night, who told me I must contact premium technical support in the morning (they were closed at the time). But premium technical support refuses to help me with this problem unless I am willing to pay $59, or $170 for a one-year support subscription, as they consider it a software support issue.

hi FoulSynthesis,

 

Welcome to the Lenovo Forums.

 

Your issue might be similar to this thread.

 

 If you have the Broadcom 43142 Wireless LAN Adapter (BCM43142) with the following Hardware ID then you may wanna check the driver below:

 

Hardware ID:

USB\VID_04F2&PID_B3BB&REV_1152&MI_00
USB\VID_04F2&PID_B3BB&MI_00

 

Driver:

Broadcom BCM43142 Wireless LAN Driver (802.11b/g/n)
h0wg01ww.exe
10.6 MB

 

If the driver above doesn't work for you, kindly follow this guide on how to find  the hardware ID of the Wi-Fi card (it's the one labelled Network Controller underDevice Manager > Other Devices) to correctly identify the appropriate Windows 7 driver.

 

 

Regards

The hardware IDs of the device labeled "Network Controller" are:

 

PCI\VEN_14E4&DEV_4365&SUBSYS_061117AA&REV_01

PCI\VEN_14E4&DEV_4365&SUBSYS_061117AA

PCI\VEN_14E4&DEV_4365&CC_028000

PCI\VEN_14E4&DEV_4365&CC_0280

 

Edit: I found this thread that addresses the hardware ID but different laptop model. I will try it out when I get home.

 

Edit 2: Yeah, it worked.
