Bugzilla Bug 143716

Hi,
I currently switched to ~x86. As I tried to start my wireless device (prism54
chipset) with

# /etc/init.d/net.eth2 start

I got:

Error for wireless request "Set Frequency" (8B04) :
    SET failed on device eth2 ; Input/output error.

According to the kernel-maillinglist this is a problem of the fireware
uploading and some kernel internas - I don't know the exact reason.
But I patched my /lib/rcscripts/net/iwconfig.sh as followed:

drunken net # diff -c iwconfig.sh.bak iwconfig.sh
*** iwconfig.sh.bak     2006-08-12 23:09:43.000000000 +0200

+       if ! ifconfig "${iface}" up ; then
+               ewarn "can not bringing up ${iface} before setting wireless
options"
+               ewarn "some wireless cards are unable to change channel etc.
before they are up"
+       fi
+
        if [[ -z ${ESSID} ]]; then
                eerror "${iface} requires an ESSID to be set to operate in
${mode} mode"
                eerror "adjust the essid_${iface} setting in
/etc/conf.d/wireless"

It works fine for me.

Nope, no bug. It allows the driver to be built non-modular.
When non-modular, the resources are not available,
at boot time, to load the firmware.

I just got this answer from kernel maillinglist. So this problem should occur
on more wlan cards.

Damn, as I notice my patch does not work perfectly. I will work on it.

Ah, the problem is that you can not set the channel before setting an essid.
The device gets allready up by iwconfig_set_mode so my last patch is useless.
But I have moved the set of the essid between the set of the mode and the set
of the channel.

Thanks for the patch :)
Fixed in 1.12.4-r4

Hi,
I've changed the summary for easier searching.
