 Posted: Wed Sep 14, 2005 3:27 am Post subject: Autoloading Firmware for Wireless NIC [solved] |
 |
|
After a long battle, I finally got my Wireless working. I have a prism card (D-Link DWL-650 rev.P) and I'm using the hostap drivers. In order for my wireless to work...I have to load the kernel module, THEN I have to load the firmware using hostap_fw_load. All together, it looks like this:
| Code: |
# modprobe hostap_cs
# hostap_fw_load wlan0
|
There are two things I want to do.
1) The card is a PCMCIA card. I want the module to automatically load when the card is inserted.
2) I want to automatically load the hostap_fw_load command when the module is inserted.
What do I do?

Okay...I don't know how...but I have the module autoloading when it's inserted.
I still have to manuall run the hostap_fw_load routine though.
Anyone got help with that last part?

Try adding the following line to your /etc/modprobe.conf file. You've stated that you have got to the point where it automatically loads the module, so this next line configures that module loading to first load the module and then runs the command to load the firmware: | Code: | | install hostap_cs /sbin/modprobe --ignore-install hostap_cs; /usr/bin/hostap_fw_load wlan0 |

That file won't get overwritted by a modules-update or any other scripts, will it?

I think it does. Hmm instead of putting it in modprobe.conf directly, try creating a file called 'wireless' in /etc/modules.d/ and add that line in there. This way it will always be in the modprobe configuration whenever you run update-modules.

That seems to work.
Thanks.

Actually...it's not working. I still have to run hostap_fw_load wlan0 every time.
Is there a way to add this to the /etc/init.d/net.wlan0 script? Or is this not advisable?
I was also told that I could do something in the preup() function within /etc/conf.d/net. But I don't understand the docs on that.
Any advice?

I just got the same exact card working with hostap_cs and I figured out how to get the firmware loaded automatically. The problem with the modprobe.conf install line is that /proc/net/hostap/wlan0/ doesn't exist for hostap_fw_load to use until after the modprobe for hostap_cs completes, and the modprobe.conf install line runs hostap_fw_load as part of the modprobe for hostap_cs so it isn't completed yet.
You must use /etc/pcmcia/wireless.opts to make hostap_fw_load happen for the specific card. Remove all the examples from the default wireless.opts and make your's like this:
| Code: | # ... comments at top of file ...
case "$ADDRESS" in
# D-Link DWL-650 rev P1
*,*,*,00:00:00:00:00:00)
if [ "$MANFID" = "000b,7110" -a "$PRODID_2" = "DWL-650 Wireless PC Card RevP" ] ; then
VERBOSE="true"
INFO="Load firmware for D-Link DWL-650 rev P1"
log /usr/sbin/hostap_fw_load $DEVICE
fi
;;
esac |
This will automatically run hostap_fw_load when the card is inserted, after loading the hostap_cs module.
Also, the pcmcia scripts try to use /etc/init.d/net.wlan0, so if you want to use Gentoo's init.d script to setup your wireless, you'll need a /etc/init.d/net.wlan0 symlink'ed to net.lo, and you'll need at least the following in /etc/conf.d/wireless:
| Code: | sleep_scan_wlan0="1"
iwpriv_scan_pre_wlan0="host_roaming 2"
iwpriv_scan_post_wlan0="host_roaming 0" |
You'll probably also want to read the comments in and use /etc/conf.d/wireless to configure access point stuff. |
