Comment 12 for bug 80499

Hi,
  I think I had a similar issue. I connect often to a DHCP wireless LAN at the University , but i need sometimes also to connect to a nother Ap wlan to control a robot. So I wrote 2 scripts in order to switch from one to another. When I started at the robot WLAN all was OK (this LAN had static IP); but when I ran the DHCP WLAN script, I was unable ro return later to the robot WLAN executing its script. iwconfig showed that WLAN connection switched to University LAN, after some seconds. Finally I found that I had to stop a dhcp client daemon AND a WPA_SUPPLICANT daemon too. Adding "dhclient stop" and "killall -q wpa_supplicant" at the beginning of my robotWLAN script was enough to end with that disturbing WLAN switching.
