Lumia 650 loses Wi-Fi connectivity until reboot

My phone downloaded updates that appear to be for the Lumia 950/XL and not the 650 and keeps trying and failing to install them and nagging me about restarts or failure to install. For me, Windows 10 Mobile was the nicest the OS has ever looked on a phone and its functionality seems more intuitive and well thought through, but when I spend money on a Microsoft phone, I expect it to just work, like Android phones do. Not to have a buggy system core, connection gremlins or other bugs which should have been eradicated before rtm. Windows Phone doesn't need to be massive to be a success. It needs only to be profitable. It can ensure a future for itself in the Microsoft stable if its creators make function and feature rich dependable, customisable beautiful, sexy phones that will work as intended for the entirety of the time before the little inbuilt self-destruct program executes itself reminding us it's time to feed the corporate monster again. A mid-range, eye-poppingly gorgeous, metallic, non-slip Surface Phone with Continuum and Hololens integration and a bug free OS would stabilise Windows Mobile sales and make it contribute more to the corporation's longevity and profitability. In the interim, fix Lumia 650 or my next phone will be another Android!

I tried what you recommended and it did seem to help.  I am not losing connection.  However, I can't trust it to be a permanent fix.  So I guess the problem really revolves around a problem with these two switches and how they affect WiFi connectivity.  

Hopefully someone at Microsoft will get the clue and fix this problem.  It is a pain to be required to check my WiFi connection frequently because it may have disconnected and is causing cellular data to be used.    This could be an expensive bug for us consumers.

Hey,

This seems to be the best option so far. My 650 is much more stable with wifi now. Even when wifi connection is lost occasionally, switching it off/on works - no need to reboot the phone!

Good one, thanks!

Exactly the same issue here. Bought two new 650s two days ago. Latest firmware and official update installed (not insider), and WiFi constantly disconnects. The phones need to be soft reset to solve the issue. I've tried all the suggestions, factory reset, device recovery, wifi sense and hotspots off, Bluetooth off. Such a shame. I got these to replace our problematic 735s after Windows 10 upgrade. Really want to stick with windows, so hope it can be fixed.

Another option is switching the LOCATION to off. Seems to work better now, but it's only a painful workaround. I need location services to be working - especially for voice navigation apps and weather.

Microsoft - wake up! My friend with 550 is thinking about the change to another system. I am also disappointed like the others in this thread. Do you really want to lose your customers?
