Got the same problem here. It looks like a software related problem. Please Microsoft, fix it!
Lumia 650 loses Wi-Fi connectivity until reboot
With my new Lumia 650 running Windows 10, I have a serious problem with Wi-Fi, occurring daily.
At some point the device becomes unable to connect to any Wi-Fi access point, whether previously known or discovered with Wi-Fi Sense. I have observed this both with WPA access points at home and at work, and also with unencrypted public hotspots in the city.
In the Wi-Fi settings screen, I can see it repeatedly attempts to connect to one of the access points available for automatic connection, but then reverts to disconnected state.
Turning Wi-Fi off and on again does not solve the problem. Only after turning the device off and on again it becomes able to connect.
Did anyone else encounter this problem?

2016-05-24T09:25:16+00:00 Hi I'm from Italy, in the Italian section of this site _Dahlia_ from MS wrote on May 9 that they are aware of the problem and they are working on a fix that will be released as a new firmware (but the timing is unkonwn).
So there is a hope, at least...
