Hi All,

Recently I have upgraded my Lenovo G580 laptop from windows 8 to windows 8.1. After up-gradation Wifi is stop working. I have checked the WIFI device driver(Broadcom 802.11n) in device manger and it is showing working fine but in the Networks section the Wifi is showing disabled.

I have search a lot but not find any solution. Please help me to find the solution for the issue.

I am attaching the screen shot of the device driver property and the my network panel.

Regards
Vivek

Quote form link: I had a similar issue.. I used the diagnostics to resolve the issue... here are the steps I took.

1) Right Click network icon in taskbar and select "open network and sharing center"

2) highlight wifi connection then at top click "diagnose this connection"
the troubleshooter will discover that the WiFi connection is turned off and offer a "apply fix" option click that and windows will enable the wifi connection...
I had the same issues as the OP and Geecat where the Fn switch just didn't work, so I worked through it as outlined above... Looks like with Win 8 the troubleshooter is even more necessary... Not sure how I feel about that, but it is what it is.


In this case, I would suggest you to check if the Wi-Fi switch on your keyboard is turned ON. You can enable the Wi-Fi by pressing the function key and the F8 key at the same time (Fn+F8 key).

Good luck hope it works. :)
