x220 got error after updating wifi driver

[caolang]

Hi, my x220 after updated the wifi driver, it got the following error like the screenshot

I can still connect to the internet through wifi but the icon on the system tray keeps showing no connection.
What should I do to solve it?

Open the wireless radios control - Fn+F5 - and power off then power on the wifi radio.

I vaguely recall having the same problem once after a wifi driver update, and that it was only resolved by rebooting the system.

Already done as you said, but not work, still have the wrong icon
