I am running FC5 on a Samsung Q35 - which has an IPW3945. I have installed the
ieee80211 version 1.1.13 subsystem, and also the ipw3945 driver version 0.0.73
from sourceforge, along with the microcode and regulatory daemons.
I prepared an ifcfg-eth1 file in the /etc/sysconfig/network-scripts directory.
I find that if I run the "load" script provided in the ipw3945-0.0.73 directory
then the wireless interface fires up beautifully.
I can shut down the interface with ifdown eth1.
However I cannot make the daemon/module load automatically via the modprobe.conf
alteration suggested in the INSTALL file.
In the INSTALL file it suggests that there should be two lines:
# echo install ipw3945 /sbin/modprobe --ignore-install ipw3945 ; \
sleep 0.5 ; /sbin/ipw3945d --quiet >> /etc/modules.d/ipw3945
# echo remove ipw3945 /sbin/ipw3945d --kill ; \
/sbin/modprobe -r --ignore-remove ipw3945 >> /etc/modules.d/ipw3945
However I presume that the "# echo" and the ">> /etc/modules...." are not
required as this makes the system fail to boot, so I put the two lines into the
modprobe.conf file as
install ipw3945 /sbin/modprobe --ignore-install ipw3945 ; \
sleep 0.5 ; /sbin/ipw3945d --quiet
remove ipw3945 /sbin/ipw3945d --kill ; \
/sbin/modprobe -r --ignore-remove ipw3945
However the ipw3945 module and daemon are not loaded after boot - and ifup eth1
do not work either. I also added a line to the modprobe.conf as
alias eth1 ipw3945
even though this was not mentioned in the INSTALL file - but this also does not
I also tried adding to the first modprobe.conf line /sbin/modprobe -q eth0 in
case the known bug in FC5 prevents the system from assigning the correct device
name but this also has no effect.
If I try ifup eth1 after booting the terminal message is:
"ipw3945 device eth1 does not seem to be present, delaying initialisation"
I am using the 2.6.15-1.2054_FC5smp kernel -
Does anyone know how to get this to work so that it knows about the wireless
interface after bootup ?
