The Win 10 update log does not list installation of any updates at all from yesterday, so it doesn't look like it was a bad driver update. If I turn the hardware wireless switch off and on again the network icon in the tray shows this, and will not list any available WiFi networks:ĭevice Manager says the device is working fine, and I have checked current driver version against that of a colleague with an identical X230i (which works fine) and they are the same: 15.16.0.2 dated 06/01/15.
I have tried uninstalling/installing various Intel Wireless drivers to no avail. I have checked that I have not done anything basic/daft like leaving Flight Mode on. What is really confusing is that if I boot the laptop with a Fedora 22 Live USB the WiFi works absolutely fine, which appears to suggest that this is indeed a Windows driver issue and not hardware failure. Yesterday morning at around 10:30 I walked away from it to do something else, and when I came back I saw that the WiFi interface had mysteriously disappeared from the list of available adapters, and now I cannot connect to WiFi at all.
My work laptop is a Lenovo Thinkpad X230i, which I upgraded to Win 10 Pro last year.
