This post reminded me of a debate we had here last week about wireless. I think some extra services are running on your laptop. Also, I think there is some miscommunication about what it means to have wireless "on". You say you have to kill wpa_supplicant manually, and I think that is a sign of the first mis-configuration. The wpa_supplicant service should be turned off in system-config-services. In there you should also have the network service turned off. NetworkManager can start a wpa_supplicant process if it needs one, and it will turn it off for you when you stop the NetworkManager. If you turn off NetworkManager and NetworkManagerDispatcher as well, then it is absolutely impossible for the laptop to automatically bring up a wireless connection. It just can't happen. Now, if you run "/sbin/ifconfig" you should see no devices. Do you see devices? My situation is like yours. I have wireless various places, and also a static IP at the office. I leave NetworkManager turned on. (network is off, wpa_supplicant is off). When I go to the office and start up, NM tries to search for wireless networks and join them, but always fails. It searches for wired DHCP as well. As soon as the network icon appears in the panel, then I click on that icon (nm-applet is the program it comes from) and turn off networking. Note I mean turn off all networking, not just wireless. Then I open a terminal and manually turn on my configured wired device, either with system-config-network or "/sbin/ifup eth0" (were I did the configuration before with s-c-n). After turning on the wire, I read the contents of "/etc/resolv.conf" to make sure the DNS server is correct. It is almost never correct, because without DHCP running, I have the last valid name server. Sometimes it is correct, and I think that is because, before I stopped NetworkManager, it scanned the environment and found a server that was willing to tell it the DNS. But that doesn't always happen. Even after going through this exercise, I still generally see the wlan0 device listed in /sbin/ifconfig output. IT is listed, but it is not associated, it has not obtained an IP number, and it does not cause trouble (yet). PJ -- Paul E.
