Tomas. I've looked at the provided logs and the kernel source-code
involved.
The logs show that the PC (I assume this is still the Prestigio 157?)
doesn't provide a radio frequency kill switch using the usual HAL
(hardware abstraction layer) identity. Here's an example of what I'd
expect to see (from a 3945ABG):
lshal | sed -n '/^udi = .*rfkill/,/^udi =/ p'
udi = '/org/freedesktop/Hal/devices/pci_8086_4222_rfkill_3945ABG_wlan'
With the 2915ABG devices here that doesn't show up either so not a major
problem. There is however a node in the /sys/devices/ tree that actively
reflects the kill-switch state provided by the ipw2200 module. Here's a
bit of code to see if your PC has the same:
KILL="$(find /sys/devices -name rf_kill)"
if [ ! -z "$KILL" ] && cat $KILL
The values reported have these meanings (from the ipw2200 source):
/* 0 - RF kill not enabled
1 - SW based RF kill active (sysfs)
2 - HW based RF kill active
3 - Both HW and SW baed RF kill active */
Depending on the result you can try manually changing it. I'd be
interested to know if it is possible to actually make the radio turn
on/off using it:
echo 1 > sudo tee $KILL
When I do that on the Vaio notebooks with 2915ABG the NetworkManager
applet reports no network device almost immediately. I can re-enable it
by doing:
echo 0 > sudo tee $KILL
If I use the hardware switch to kill the radio I see:
cat $KILL
2
If the ipw2200 module has no control over the state of the radio kill
switch - if it can only read the status - then I'm going to close this
bug as Invalid (since it isn't a problem with ipw2200) and move to your
other specific bug #53953 "change 'acerhk' to use 'autowlan=1' by
default".
