    WiFi not working on Windows 8.1

    I need help to find out how to stop my wifi from dropping on newly installed Windows 8.1 laptop.

    I am facing this problem since the first day I upgraded my PC from Windows 7 to windows 8.1 pro. I have tied many things like troubleshoot, install and uninstall drivers from Intel itself. I donít know why I am facing this problem. At the moment I am accessing my internet through my Smartphone.

    Need urgent help from you all. For more reference to the problem, here are my computer details:
    • Model: Lenovo G580
    • Processor: Core i5 (3rd Gen)
    • Clock Speed: 2.5 GHz with Turbo Boost Upto 3.1 GHz
    • Chipset: B75 Express

    There must be some problem with Wifi of your laptop as you said if you can connect the phone to the same wifi. Just get it checked once maybe its not an internal issue.

    While upgrading process, Microsoft also updates the Network Adapter driver and that have caused the problem for many. Therefore, you are advised to Revert Network Adapter Drivers to manufacturer release.

    I had same problem after 8.1 update this is what I did to fix. I downloaded the newest Intelís Wi-Fi driver from intel.com. Try to update WLAN card's driver as well. After a long research this solution finally solved my problem hope it helps you too.

    Even I am using Lenovo G580 which has a Broadcom 802.11n Network Adaptor, Initially even I was facing this problem but then this was suggested by my engineer and now I am not facing any problems using my Wifi.

    Here are the instructions:
    1 Go to search and type Device Manager.
    2 In the middle you will see 'Network adaptors' option, doublee click on it and then double-click on Broadcom 802.11n Network Adaptor
    3 Click on the Driver tab which is on the top of the bar and click the Update Driver... button
    4 Click on 'Browse my computer for driver software'
    5 Click 'Let me pick from a list of device drivers on my computer'
    6 Click the "Broadcom 802.11n Network Adaptor (Broadcom)" entry from the list, and click Next

    Well, it worked for me.
