I tried the upgrade from Win7 to Win10 and the upgrade went pretty smoothly. Everything seemed okay when it completed and I was using it for an hour or more. Then I went off to do some stuff and when I came back and the computer woke up I suddenly had no network connections at all. I checked a bunch of stuff until I noticed my network adapter showed disabled, I reenabled it with no problem and the network started working again, but the next time I went to use my computer it was disabled again, since then it has disabled it right in the middle of me working on the net. Sometime I have had to reboot to get it working again but inevitably it gets disabled again. I am going to go back to win7 unless there is a known solution to this.
