I made the upgrade to Windows 10 on another machine and in short i am unable to connect to any wifi networks.
When hovering over the icon in the toolbar it says that it is not connected to any networks and that there is networks available, selecting network settings then wifi causes the computer to crash, clicking the icon as well does not show the available networks.
I have a netgear AC1200 plugged into a usb 3.0 port, there is a white light flashing on the button on the side of the antenna.
uninstall the drivers for the netgear and redownload them if they don't have them for windows 10 use windows 8.1
My desktop was acting strange too after upgrading to 10. I reinstalled all my chipset and LAN drivers but it still was acting funny. My network and internet connect was really slow. I eventually did a clean install of 8.1 but it asked me if I wanted to upgrade to 10 during the installation process and now everything seems to be working just fine.
so updated drivers and am still having issues, when i first boot my system up i can see the wifi network now, enter the password and it doesnt connect, then it goes back to the same issue i had before with the window being blank and clicking wifi in network settings crashes the program
Any firewall/virus scanners running? With the whole wifi sharing nonsense in win10 you have to turn off things like 'blocking internet connection sharing' in order for the connection to work.
I spent an hour on a mates PC yesterday fixing this exact issue - was running Bitdefender, after the latest forced update he lost connections past his access point. Flushed everything, swapped wifi adapters then ran wireshark and saw that the Bitdefender firewall was blocking 'the shared internet connection' not that there was a shared connection but none the less turning off that blocking feature in Bitdefender fixed it.
In short once you see that its connected fire up wireshark and check out the events.
