ThinkPad T450 (Intel Dual-band 7265), running Windows 10 Pro, everything updated via Windows Update and Lenovo Vantage. After turning on Airplane Mode, and then turning it off, my Wi-Fi stays off (but Bluetooth seems to be back on) and I have to run the troubleshoot to enable it again.
Previously my Wi-Fi also wouldn't turn back on after sleep, but this was fixed by going to Device Manager and unticking the box that says "Allow the computer to turn off this device to save power". The other aforementioned problem still persists, though.
