Finished: CALL FOR TESTERS Intel wireless 5100/5300 iwn(4) driver for FreeBSD

dduong · Dec 20, 2009

I can also say that I haven't had any issues on rev26. I'm running 8.0 (AMD64) on an X200 with an Intel 5300.

LesJen · Dec 21, 2009

Hello
I've upgraded as well, it took a little while to figure out that I needed to load yet another module (iwn5000fw.ko).
Now wlan0 connects but not to the network specified in wpa_supplicant.conf!
I get an IP-address from someone elses network! How do I avoid this?
Thanks
/Leslie

oliverh · Dec 21, 2009

Without any further details it's just wild guessing.

What details would you like me to provide?

oliverh · Dec 21, 2009

Your part of /etc/rc.conf regarding the wifi config and /etc/wpa_supplicant.conf _without_ your password ;-)

LesJen · Dec 21, 2009

I just want to ad that this config worked with v.24 of this driver!

rc.conf

Code:

wpa_supplicant_enable="YES"
wlans_iwn0="wlan0"
ifconfig_wlan0="WPA DHCP"

wpa_supplicant.conf

Code:

ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=0
ap_scan=1
#
network={
        ssid="my ssid"
        scan_ssid=1
        priority=1
        psk="hidden password"
}

eyebone · Dec 22, 2009

so finally some time to test it. rev. 26 compiles and works so far on:

Code:

kernel: iwn0: <Intel(R) PRO/Wireless 5300> mem 0xf2500000-0xf2501fff irq 17 at device 0.0 on pci3

wpa_supplicant with WPA key + AP connection working perfeclty, doing some stress tests ...

observations i made:
1. changing the mac address of wlan0 ends up in a flapping connection with a former working wpa_supplicant configuration.

Code:

kernel: wlan0: link state changed to DOWN
kernel: wlan0: link state changed to UP
kernel: wlan0: link state changed to DOWN
kernel: wlan0: link state changed to UP

2. changing both, wlan0 and iwn0 to the same (fake) mac address results in no connection to the AP at all, even no flapping stuff.

3. i tried the also the aircrack-ng suite, now listening for other networks seems so far not to work i guess this would be also the same for injecting, but i didnt test that so far

if you need wpa_supplicant output i can paste you, but i guess you can reproduce the problem without problems.

in anyway thank you for a working wireless driver

!!

regards,

LesJen · Dec 22, 2009

If I have ifconfig_wlan0="WPA DHCP" in rc.conf. It will connect and work.
If I have ifconfig_wlan0="inet 172.17.0.159 netmask 255.255.255.0" it won't connect!
Any ideas on what's the problem?

Never actually tried that, added to my TODO list.

Yup, radiotap/monitor mode is another point on the TODO list.

Add a SSID maybe?

LesJen · Dec 22, 2009

I saw now in the handbook what you mean! Unfortunately it won't connect with the line:

ifconfig_wlan0="ssid my_ssid inet 172.17.0.159 netmask 255.255.255.0"

Is there anything else I can do to make it connect?

bschmidt · Dec 22, 2009

LesJen said:
Do you mean the SSID that I have in wpa_supplicant.conf? Where should I put it?

Code:

ifconfig_wlan0="ssid YOURSSID 172.17.0.159 netmask 255.255.255.0"

LesJen · Dec 22, 2009

I've tried now for more than ten minutes. It won't connect when an IP-address is set. DHCP is ok. If it's dependent of the ssid parameter when setting the IP-address, how come the ssid is not needed when using DCHP?
Could it be something else that's preventing it from connecting?

robbak · Dec 24, 2009

In the first line you were trying to connect with WPA (ifconfig_xxx0 WPA DHCP). Now you are trying to connect without it (ifconfig_xxx0 ssid YOURID youraddress netmask yournetmask)

Have you turned off encryption on the network, or have you just forgotten WPA?

oliverh · Dec 25, 2009

Using rev27 for about an hour without any problems so far, runs very smooth

Thank you very much for this answer

No I have not turned off the encryption! But I have forgotten to put WPA in the ifconfig line. Very observant of you and I need to polish my glasses

PS: SSID is not needed now

dduong · Dec 27, 2009

Is there a way I can check the rev that I'm using? I want to know if I applied the svn patch correctly.

Thanks!

If you mean something like

Code:

iwn revsion XY loaded

then no, there isn't.

The best way to ensure that you are using the latest SVN version, is to remove any if_iwn.ko and iwn??00fw.ko modules from /boot/kernel/ and checkout/build the driver afterward.

dduong · Dec 27, 2009

Thanks bschmidt.

I've recently upgraded my X200 to 4gb of RAM and after checkout/build of the rev 27 driver plus recompile the kernel; everytime I start wpa_supplicant, my wireless LED shows up and my whole laptop crashes and reboots. I enabled the debug and this is what I see:

Sorry, I'm new to this whole debugging process and I've only learned how to do it from the previous posts. I will try to provide you as much info as possible if requested.

bschmidt · Dec 27, 2009

Did you build/install the kernel before or after you've compiled the wireless driver? I just ask, because if you install a kernel afterwards it overwrites the wireless driver.

dduong · Dec 27, 2009

I built/installed the kernel after compiling the wireless driver.

I assume that I was suppose to compile the wireless driver without build/install the kernel?

bschmidt · Dec 27, 2009

Exactly, there's usually no reason to rebuild the kernel, just the driver is enough.

Let me know if the panic still exists.

dduong · Dec 27, 2009

Thanks!

Here is what I did so far.

1) Removed any if_iwn.ko and iwn??00fw.ko modules in /boot/kernel/
2) Build/Install kernel (start things from scratch)
3) Followed your instructions on post #16.
4) For kicks, I've rebooted

Unfortunately that is still an old driver, the latest version doesn't print the 11n rates.

Can you do

Code:

# ls -l /boot/kernel/if_iwn*
# svn co http://svn.techwires.net/svn/projects/freebsd
# cd freebsd/sys/modules/iwnfw
# make
# make install
# cd ../iwn
# env CFLAGS=-I$PWD/../../ make
# make install
# ls -l /boot/kernel/if_iwn*

and post its output?
