When I use wireless network,the network status icon show up wireless connection icon.WIFI connection status icon

But when I use command ifconfig wlan2 down to disconnect wifi,the network status icon still show up connection status.

The network status has not changed to disconnect icon.WIFI has already disconnected network,but the status icon still show up connection.

How can I to fix the status icon sync problem?

My ubuntu version is Ubuntu 14.04.1 LTS

Okay, here is an answer that should work. To disable the wifi card, you can disable the kernel module by running the following command:

sudo modprobe -r iwlwifi

If this works, the icon will usually update immediately.

To re-enable the kernel module to bring the device back up, run the following command:

 sudo modprobe iwlwifi
