I'm on 10159 and my SP3 is now losing wifi ability upon sleeping. When it wakes, wifi is turned off. When turned on I get nothing. Reboot required.
How did you get 10159 on your SP3? I only had an option to install 10130.
Interesting, my SP3 had the exact same problem... on 10130. Since upgrading to 10159, I don't see that issue anymore.
Actually you can go straight to 10163 now. Just download the ISO and use it, either by making a bootable USB drive (for a clean install) or mount the ISO and run setup.exe to upgrade.
I actually lasted 24 hours this time on this build with my SP3, till I got completely frustrated with the tablet mode and went back to W8.1. If you have a desktop, laptop, IMHO this a great O/S. But for a touch system, forget about it. Microsoft still has some more bugs and interface changes to make before it's really ready for tablet systems (again IMHO).
I'm seriously thinking about unregistering my system for the W10 upgrade, unless they do something about it quickly.
