I'm using a refurbished Lenovo ThinkPad T430s with Windows 10. It was working fine, but a couple of days ago, it randomly switched to airplane mode, and when I attempted to turn it off, I got a menu box reading 'turn wifi on' with an options box that doesn't actually work. What do I do? I tried the following:
Toggle the Wi-Fi switch. Doesn't work.
Press fn-f2 and fn-prtscrn. Doesn't work.
Block IPv6. Doesn't work.
Ran troubleshooter. Only got an unhelpful message telling me to use the switch to turn it on.
Network reset. Nothing changed.
Toggle Wi-Fi from the menu. The switch goes right back to the off setting.
Change channel width settings. Still nothing.
What do I do? I'm at my wits end here.
