I have uninstalled access connections, re-installed it, uninstalled it. I have tried every single driver, currently at 18.104.22.168. When I Fn+F5 all I get is the bluetooth option. In the Device Manager the adapter is showing up, with an exclamation mark, the details say "The device cannot start, (Code 10)". I took apart the laptop, re-inserted the card, checked the antenna connections. I booted from a USB Linux, wireless will not work in that OS either.

The error your getting is ether a hardware or driver issue within device manager and I suggest you
completely uninstall the Wireless driver and reinstall it. Then check and see if the error still happens.
You can also try to roll back the driver first and or use system restore to bring the computer back to time when it was working.

Ok so can you try to now uninstall and reinstalll from the link the correct driver? This would be my next suggestion.

Okay, rolled back to 22.214.171.124 and now the device is showing as installed, Code 10 is gone, shows up in Fn+F5, still not working though.
Sure sounds like the switch is the culprit, as others above, have observed. Are you still under warranty? Might be time for a trip to depot service, or on-site, if you've got it.

Got it resolved on my machine. The problem is definitly in the hardware button and can be resolved as follows but first ensure the machine is not still under warrenty else just take it back have the button replaced.
1. Backup machine and switch off.
2. Remove battery.
3. Turn machine upside down and remove hdd and memory moduals.
4. Unscrew all keyboard and palmrest screws. (about 11~12 in my case)
5. Push the keyboard and palmrest loose via the access holes.
6. Turn machine around and unplug the keyboard and palmrest.
7. Pull the top side panel loose thats on top keyboead/screen.
8.(note the toggle switch sits under the motherboard pci card) so you will have to remove all the mb screws to make space for you to lift the mb without breaking or removing the mb. You want to remove the toggle switch that is mounted to the chassis.
9. In my case I had to remove about 8~10 screws.
10. Slowly lift the mb up till the toggle switch is sepperated from the microswitch.
11. Unscrew the toggle switch and remove it. Note the on position for the micro switch and set it to on.
12. Reassemble the unit by reverse following steps 10 to 1.

I just downloaded the newest Lenovo solution Centre, it does not even pick up that there is a problem. Downloaded Access Connections to see if that would help, no.
If I uninstall the device, scan for changes, it picks it up again, will not start it.
Tried a new card, I think it was an 1802 error, laptop would not boot, said incompatible wifi card.
Very frustrating, using a Belkin USB wifi stick, not what I want to do.
Pretty secure in the fact that unless someone comes up with a solution to what appears to be a widespread problem, my next laptop won't be a Lenovo.

I also had a problem with my wifi not being detected. Turning the wifi switch off and on again didn't resolve the issue and the hardware didn't show up in the device manager.
I resolved this by turning the machine off and removing the battery, turn it back on without the battery. Now it did detect the wifi and i was able to connect to my network again. While the machine was still on I put the battery back into the machine and it kept working, even after rebooting. I havent had a problem with the wifi since.
I hope this is helpfull to you who have the same issue i had.
