I'm running a Thinkpad T430s with a fresh install of Windows 10 Pro. After a few days, the wifi disconnected and won't reconnect. Wireless card is Intel Centrino Advanced-N 6205.
Network Settings has the wifi switched to off. Clicking it to switch to on changes nothing - it shows as on, but connections don't work, and if I close the Network Settings window and re-open, the switch is back to off.
Windows 10 will not switch off of airplane mode. Clicking the mode button does nothing - the icon stays blue. Ethernet works fine. An external USB wifi dongle works fine, but I'd like to use the built-in wifi.
Things I have tried:
Run all updates through Windows Update.
What else can I do? Is this a motherboard problem? Warranty is expired on the machine.
Solved! Go to Solution.

Have you inadvertently just turned off the WiFi Radio via the switch that is, I believe, located on the right side of the laptop up front?
Even if it is on, try toggling it a few times and see if the WiFi radio will turn on. If not, the switch may be bad, but can be replaced, or the ribbon cable just loose.
If it were me, I would probably spray the switch with some electronic cleaner to clean it, and if need be, remove it to clean and check the ribbon connection to see if after cleaning it works.

Have definitely toggled the hardware switch many times. I'll check the ribbon cable. I'm not very handy so this is a little intimidating, but it's worth a shot.

Be sure to keep track of all the screws and what parts they hold, because they will all start looking the same after a while yet are not (snack sized ziplock bags and a permanent marker work great), and take lots of digital photos and notes as you go along.
In case you need to order parts
Description Part Number
Bluetooth Switch Board 04W1700
Bluetooth Switch Cable 04W1687
I found this (both switch and cable) with a quick search, but a more thorough search might find a better deal.
