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
