I've seen numerous threads in late August regarding Wi-Fi disconnecting since Windows 10 upgrade. Add me to the afflicted. I've not seen a solution though. When I Troubleshoot the Network by right-clicking Wi-Fi icon it simply tells me to turn on Wi-Fi switch on laptop but it is already on. Sometimes it switches me to Airplane mode for no reason. Always after Sleep. It then will recognize no networks or available Wi-Fi.
The only solution is to reboot the laptop every time and this is frustrating. Is there a solution. My laptop is a Toshiba Satellite L305D. Thanks.
