This problem just started two days ago (Wednesday June 14th, 2017}. I have an HP pavilion g7 laptop running Windows 10 version 1607 os build 14393.1358 When the laptop starts up it shows that I am connected to my network and have internet access. When I enter my password to log onto the laptop the adapter is shut off and I have no network connection. I go into device manager and it shows the device is working properly. I have tried a system restore, but get a error that is cannot complete the operation. I have ran checks for virus and malware and have found none. I know my network is good because I am using another computer on the same network. Also I have tried to use a cable to the router and still no luck. Any suggestions or solutions?
