Windows 10: Wifi-connection lost after uprade from 7 to 10.

I upgraded from windows 7 to 10-when finished there was a red cross through the wifi icon.Having read numerous forums,I established that there was no old VPN software;I updated the Broadcom 802.11b/g/n software and in network adapter properties,I unticked power management switching off the adapter;also,altered bandwidth to 20_40MHz.As soon as I clicked on that,the wifi switched on!It then works until the computer is switched off;when on again,same problem.If I go to network adapter properties,and disable and then re-enable the adapter,wifi comes on again.I am at my wits end.Has anyone please,please,please got a solution.

Lost internet connection after upgrading to Windows 10

Hi,

I upgraded to Windows 10 from 8.1 (with keeping personal files and applications). Everything was fine after uprading.

After about 15 minutes my PC lost LAN internet connection. i tried to restart the PC but still no internet connection.

What can I do now?

Thanks

 

After upgrading to Windows 10 Wi-Fi connectivity is unstable.

Yes, I have seen these symptoms on other notebooks with earlier Windows. The fix is to download the Wi-Fi switch utility or Quick Launcher, install it and configure it to always enable Wi-Fi and Bluetooth on startup.

 

Thank you.I will try it.

 

I have tried to install quick launcher-all it does is to give me the option of launching IE when I use Firefox.

 

Isn't there a key combination to enable Wi-Fi? If you press that you may see a little window where you can configure Wi-Fi to be always enabled.

 

I pressed fn+f3-switched wifi off;pressed again to switch on-no wifi-had to go back to network adapter properties-click install and wifi back.Aaaargh!!

 

NetSetMan Freeware | Network Settings Manager for Windows (LAN WiFi)

Setup wifi profile in this free app and after startup it should enable it.

 

Thanks for your advice.Unfortunately after switching off and restarting the laptop,I am back to square one.I have to go into device manager-network adapters-network driver-disable and then re-enable and then it starts!
