  • I tried both methods, but neither worked. All my network adapters show up in the device manager, but none appear in the network and sharing center adapter dialog box. I was using Cisco VPN Client V 5.0 and Cisco connect anywhere softwares.

  • question Since I cant download anything I have to try the second fix. After I type that first string it asks me yes or no. which do I pick?

  • Kapil Arya

    ^^ What question you’re getting for those yes/no option, please let me know.

  • After I typed in the first string I got an error report that said that it was unable to find specified Registry key or value.

  • Kapil Arya

    ^^ Have you tried Automated Troubleshooter already?

  • fIX 22 has solved the problem for me. Thanks bro :-) ;-)

  • Kapil Arya

    ^^ Glad we could help :)

  • The troubleshooter says it finds nothing. I entered the reg delete command in command window I got an error report that said that it was unable to find specified Registry key or value.
    Initially my problem was the OS kept turning off Wifi. After applying recent Win10 upgrade yesterday (12/26/15) WiFi stays on, and I am able to connect to home networks. They prompt for netkey, accept it, and say they are connected, but with no internet access. Looking at performance tab in taskmgr, I see no traffic whatsoever either direction on the Wifi connection. I am connected to one of the home networks via Ethernet, and that is working fine.

    I do not have VPN software installed. I MAY have had my corporate vpn tool installed before the upgrade, but can find no trace of it now so am unsure of that. I had not used it in a long time since they changed methods and I just don’t recall if I ever put it on this machine.

    I I have a Gateway PC with Qualcomm Atheros AR5b97 adapter. Driver is dated 2006 but Windows says it is current.

  • Kapil Arya

    ^^ I guess you installed the November update that resolved the problem :)

  • Everything I described above was AFTER the upgrade. I had to force the driver upgrade. Windows kept saying mine was current. Downloaded it and ran its setup.exe. Once I did that and then rebooted the router, I was back in business.

  • Kapil Arya

    ^^ Glad to hear problem is resolved!

  • My problem is I can’t connect to the internet and you tell me to download a file? Am I missing something here? You want to tell me how to download a file when I can’t connect to the internet?

  • Kapil Arya

    ^^ You may download it on another device and then import the file on issued device.

  • Both soultions didn’t work for me, any other suggestion?
    The second one kept saying an error!

  • Kapil Arya

    ^^ Try Network Reset: https://www.kapilarya.com/how-to-reset-network-settings-to-default-in-windows-10

  • When I applied the command in fixed #2 (did a copy and paste to make sure I entered it correctly), It said the system was unable to find the registry key or value. What next? I still do not have Wi-Fi settings on Windows 10 version 1803 installed 5/17/18
