Which wireless card/driver are you using?

On this x86_64 X60 (1709-CTO) with the Intel 3945 option, running
Kubuntu 7.04 and using KNetworkManager, turning the switch off:

May 30 17:50:38 detritus kernel: [   15.410612] ipw3945: Radio Frequency
Kill Switch is On:
May 30 17:50:38 detritus kernel: [   15.410615] Kill switch must be
turned off for wireless networking to work.

The WiFi led goes off and predictably pings fail.

Then, turning the switch on:

May 30 17:51:13 detritus kernel: [   50.090384] ipw3945: Detected
geography ABG (11 802.11bg channels, 13 802.11a channels)
May 30 17:51:22 detritus kernel: [   59.385447] ipw3945: association
process canceled

That "association process canceled" message seems harmless, as the
network is functional, complete with the led back on.  This is on a
WPA2-PSK WLAN.

I also had the kill switch working without apparent problems earlier
under Debian unstable on the same machine.
