Argh, is this the reason why compat-wireless(wireless-testing?) today
doesn't quite work any more?
NetworkManager no longer wants to work, with this message in syslog:
localhost NetworkManager: <WARN> nm_device_wifi_disable_encryption():
error setting key for device wlan2: Invalid argument
and trying to do it by hand give this error:
#iwconfig wlan2 key restrict <key>
Error for wireless request "Set Encode" (8B2A) :
SET failed on device wlan2 ; Invalid argument.
This is v2.6.30-rc5-23297-gbf2c6a3 ; the last time I had a working
compat-wireless was only a few days (<5) ago.
