And I know the wifi was working because it was working when it was running windows 7. I've never had such a difficult time with a laptop. Even though I can connect to the internet via an ethernet, the LAN designation doesn't even show up in the window for Sony Smart Network Utility. According to what I've read and the images I've seen, when I open the network utility it should not only show an 'on/off' slider but it should also be showing all my various types of connections - LAN, WAN, etc. I think it has something to do with Sony's Smart Network utility (which isn't so smart). Bummed and tiredīelieve it or not, I tried a USB wifi adapter and even that wouldn't work. So here I sit with my laptop and no wifi (and a very long ethernet cable running across my living room - which I tried to pass off as part of my shabby chic motif but not convincingly. It'd be easier to make a luncheon appointment with God. Tried contacting Microsoft tech support for windows 10 by phone - fugedaboudit. Sony's out of the computer business and no longer offering support. This is clearly a conflict between Windows and the Sony built in Smart Network software/utility.

Have reinstalled windows 7 from the OEM Recovery Partition and then performed Windows 10 upgrade (again) all to no avail. Have replaced the wifi card - still no wifi. And although I have it set to 'on' still no wifi. I have Sony Smart Network utility to turn on and off the wifi (no physical switch on this device). No matter what I've tried I can't get the wifi to turn on. I have this problem with a Sony SVE1511RFXB since I upgraded to Windows 10 a couple weeks ago. Thought I’d post the solution here since I couldn’t find it posted. I actually ended up buying and using an external plug in usb wifi for about a year now… just found out it’s some bs software that came with machine that got some random update that caused it to override the windows software. If you went into the wifi settings to turn it on, it may indicate that it is turned back on, but if you closed it and went back in it would be off. Windows would indicate that the wifi was turned off, but there is no physical switch on this machine. Longer story: Wifi intermittently stopped working and eventually stopped working all together (made me think there was something physically wrong with the wifi card). Solution: Make sure the wifi is turned on/enabled in the “VAIO Easy Connect” setting (green box with arrows) in the taskbar, do not uninstall the software, it creates new problems and Sony no longer hosts the software to reinstall. Problem: Wifi card inexplicably disabled, unable to enable wifi from windows settings
