Question

My machine details:

Machine: G580

Model: 20150

OS: Windoews 7 Ultimate 32bit

 

When I tried to connect WiFi it showed me that a WiFi adpater is missing. After that I attempted to download WiFi adapter drivers from Lenevo website but still it is showing that my WiFi adapter is missing..

 

Could this be a hardware issue or drivers issue?

Answer

There are various factors that can cause this issue. Three possibilites I could think of right now. Please check the details below.

 

1) Driver Issue

If it is a driver problem then you should have a yellow icon in Device Manager -  "Network Controller" or "Unknown Device" with exclamation mark yellow icon. Please see illustration below.

If this is the case, you are required to download the wireless drivers from our support site http://support.lenovo.com or by clicking the link below. Please check which wireless card your machine has and then select and download the correct drivers accordingly.

 

Windows 7 - G580 (model 2189,20150)

 

Windows 7 - G580 (model 2689, 20157)

 

2) BIOS Wireless LAN is Disabled

You may want to check your BIOS settings as it has an option to disable the WIFI hardware.

 

  • Go to BIOS by tapping F2 or FN+F2 once you power on or restart your system.
  • Once inside BIOS Go to the "Configuration" tab
  • Look for "Wireless Lan" and make sure it is set to enabled.
  • Then hit F10 on your keyboard to save and exit BIOS. (Please see illustration below)

Does anyone know if there is a wifi module upgrade available for G580?

Mine is maxed out at 54MB/s ... I want to increase the speed to at least 150Mb/s like most other laptops on the market.

Hello Techs,

 

I was using Lenovo -G580 and recently degraded to windows -7 Ultimate , since windows 10 wifi drives are not available for lenovo G580., so I degraded to Win-7 and tried to install appropriate drivers from lenovo site but it could't work out.

 

I had done some validations in BIOS (its Enabled) and Device Manager it shows Brodcom was installed.

 

Any suggestions??

Thanks,
