I am assuming you clicked the icon to bring up 'ipinfo' after you killed the modem (it's showing the IP address). If so this is almost certainly a bug with the driver.
Can you try one test for me please to confirm this?
While the modem is off and the icon is still showing, open a terminal and run this command please:
Code: Select all
ifconfig wlan0
'ifconfig' is a mature program, part of the 'wireless-tools' suite of programs.
Thanks.
