How to fix WLAN Connection failure on Lenovo Tab 10? Did something break?

Added (1). This used to work fine with the same Wi-Fi connection, bought it in november, just lately it is not connecting to my home network, I get that failure error after entering the password

Added (2). I haven't tried to connect to another network yet, and other Wi-Fi devices in the home can connect fine.

Might need some driver reinstalled. Contact Lenovo for the support that you already paid for.

Restart might solve your issue
