[solved] rt73: SIOCSIFFLAGS: Cannot assign requested address

Live forum: http://rt2x00.serialmonkey.com/viewtopic.php?t=4755


26-04-2008 12:20:45

After 2 months of searching and trying, I ask for help.

I have an D-Link DWL-G122 C1 (clever me!! (). When I try to startup the wlan0 interface via ifconfig it gives me [code1arbs3ak]# ifconfig wlan0 up
SIOCSIFFLAGS: Cannot assign requested address[/code1arbs3ak]

At the current stage I have these settings

1. I'm using the rt73-cvs-2008042605 driver (from the daily build).

Compilation/Installation is fine. No problems.

2. The driver seems to load properly. No error reported

[code1arbs3ak]# dmesg | grep rt73
rt73: init
rt73: idVendor = 0x7d1, idProduct = 0x3c03
rt73: using permanent MAC addr
rt73: Active MAC addr: 00:00:00:00:00:00
rt73: Local MAC = 00:00:00:00:00:00
usbcore: registered new interface driver rt73[/code1arbs3ak]

Firmware seems to be the latest [code1arbs3ak]# md5sum /lib/firmware/rt73.bin
bd733372ae21a010bf8a5511d7711c2d /lib/firmware/rt73.bin[/code1arbs3ak]

Although MAC 000000000000 confuses me ... ?

I've blacklisted some kernel-drivers as recommended
[code1arbs3ak]# cat /etc/modprobe.d/blacklist | grep rt
blacklist rt2500usb
blacklist rt73usb
blacklist rt2x00usb[/code1arbs3ak] and they don't seem to load [code1arbs3ak]# lsmod | grep rt

usbcore 89584 8 rt73,sl811_hcd,usbhid,ohci_hcd,uhci_hcd,usb_storage,ehci_hcd[/code1arbs3ak]

3. I'm using a 2.6.25 kernel
[code1arbs3ak]# uname -a
Linux moghedien 2.6.25-gentoo-r1 #2 SMP Tue Apr 22 21:49:57 CEST 2008 i686 Pentium III (Coppermine) GenuineIntel GNU/Linux[/code1arbs3ak]
This because I spotted that the ralink drivers were updated from 2.6.24.x to 2.6.25 and thought that new drivers would have solved my problem. They didn't.

... and, oh yes, it's a Gentoo system. So the .config is highly modified. Should I post it as well?

4. My WLAN-Router is now completely free and open, since I tried to avoid Auth/Encryption-Problems. I just want to get contact. This failed.

I don't have WEP, WPA or MAC Filtering enabled. This is ok, since I'm at the country side ...

5. Some additional data

[code1arbs3ak]# ifconfig -a

6. As there is no BSSID/AP set, I tried to set it manually

[code1arbs3ak]# iwconfig wlan0 ap 00:01:e3:e2:0d:b7
Error for wireless request "Set AP Address" (8B14) :
SET failed on device wlan0 ; Network is down.[/code1arbs3ak]
which leads me directly to [code1arbs3ak]# ifconfig wlan0 up
SIOCSIFFLAGS: Cannot assign requested address[/code1arbs3ak]

Pluging this *+!@@#$-stick into some Windowz-Maschine works. cry

7. The LEDs on the stick are off. No blinking, no nothing.

8. Yet another issue which puzzles me

[code1arbs3ak]# lsusb

Gives three troublesome lines at the end ... huh?

I know pretty much input up to here, but I really, really googled and tried a lot to get it working.

What's wrong? Do I miss something? HELP! cry

... and, OH, BTW once running a rmmod - modprobe -v rt73 sequence the module crashed, leaving some relicts in kernel space, freezing my system.

Hi dyle71,

A MAC address of all zeroes means that although the operation to get that item from the adapter's EEPROM has been done without an error indication, the actual data was not obtained. All the other symptoms are probably due to the same thing that caused the MAC address failure.

First, make sure there are no collisions i.e. only one instance of one version of the driver is present[code3jqgp1nr]lsmod|egrep ^rt[/code3jqgp1nr]Specifically, if you wish to use the legacy driver, you need to make sure the version shipped with the 2.6.25 is not enabled. If you wish to use the nextgen driver, make sure there are no scripts that load the legacy driver. If the nextgen driver has been compiled into the kernel, the lsmod trick won't show you that it's there. Check your .config file.

Next, just try unplugging the adapter, then plugging it back in.

If that doesn't work, build with debug enabled, then modbprobe with "debug=15" as a parameter, followed immediately with an rmmod. Attach a gzipped copy of /var/log/debug to a posting here, and I'll look at it.



28-04-2008 03:55:27

Hello Vern,

Thank you for reply!

Plugging in and out doesn't help.

I also followed your advice, but run into that crash I reported in the first post. Basically, when removing the rt73 module, it sweeps dmesg with lots of

As there's this "Oops ... SMP" I removed SMP from the kernel and that solved the crash.

But still the driver doesn't work. So I reconfigured the kernel to not contain anything that smells like rt2x00/rt71/rtsomething. I had it set as module and blacklisted them before ... now I'm pretty sure the kernel doesn't know [i1xrkpgiz]antyhing[/i1xrkpgiz] about rt2xx drivers [code1xrkpgiz]# zcat /proc/config.gz | egrep CONFIG_RT[x276]
# CONFIG_RT2X00 is not set[/code1xrkpgiz]

So ... attached you find my debug.gz. It has been made as such
1. device unplugged
2. modprobe -v rt73 debug=15
3. plugged in the device
4. rmmod rt73
5. cp log

Hence, the device is still plugged in when I copied the log, although the driver complains that the device is disconnected a thousand times ... ???

Wired ... should I increase the debug level up to 31 as suggested in the TESTING file, which ships with the driver?

Another question you said [quote1xrkpgiz]Specifically, if you wish to use the legacy driver, ...[/quote1xrkpgiz] What are my chances? I've tried the drivers from the
- RaLink homepage - nada
- Kernel 2.6.24 and Kernel 2.6.25 - nada
- serialmonkey rt73 - ... ?

Is there any other possibilty I can try?


28-04-2008 20:23:16

Hi dyle71,

Took a quick look at your log. Basically, as soon as we try anything that uses the downloaded firmware, we end up thinking the device is not there. I don't know why.

Does the file /lib/firmware/rt73.bin match *exactly* with the CVS version of rt73.bin? If not, can you copy the CVS version of rt73.bin into /lib/firmware and try again? Alternatively, doing (as root) "make install" copies the firmware file and also creates an alias in /etc/modprobe.d/ralink (2.6 kernels) or /etc/modules.conf (2.4 kernels).



29-04-2008 03:14:00

Hi Vern,

Thank you for trying.

However I'm pretty confident, that the firmware file is correct
[code2tzqql44]# find /lib/ -name "rt73.bin"
# md5sum /lib/firmware/rt73.bin rt73-cvs-2008042605/Module/rt73.bin
bd733372ae21a010bf8a5511d7711c2d /lib/firmware/rt73.bin
bd733372ae21a010bf8a5511d7711c2d rt73-cvs-2008042605/Module/rt73.bin
# ls /etc/modprobe.d/
blacklist ndiswrapper pnp-aliases ralink
# cat /etc/modprobe.d/ralink
alias wlan* rt73[/code2tzqql44]

But as you mentioned the /etc/modprobe.d I also looked at the ndiswrapper and come up to a [code2tzqql44]# cat /etc/modprobe.d/ndiswrapper
alias wlan0 ndiswrapper[/code2tzqql44]

Could this mean anything?

... or are there any kernel-switches I'm missing for firmware/wlan functionality? Hence, since this is a Gentoo system I play around with the kernel a lot and things don't have to be as they are on other binary based distros ...

edit should I create another debug-dump? With a hight log-level? Which one?

edit2 is there any other driver possibility for me despite the drivers of the RaLink Homepage, the kernel ones and rt73 of serialmonkey?


29-04-2008 03:54:47

Hi dyle71,
[code3r5886df]alias wlan0 ndiswrapper[/code3r5886df]Basically says whenever a reference to wlan0 is found, load ndiswapper.[code3r5886df]alias wlan* rt73[/code3r5886df] says whenever you find wlan<anything>, load rt73. Looks like there may be a collision here.

Try getting rid of the alias for ndiswrapper and see what happens.



29-04-2008 04:40:53

Ok. I mv'ed the ndiswrapper file away, updated the module-db and rebooted.

No progress (

However, as above I created a debug-dump but this time with debug=31.

Right at end of the dump it states
[code30xicyjp]Apr 29 06:22:40 moghedien rt73: init
Apr 29 06:22:40 moghedien rt73: idVendor = 0x7d1, idProduct = 0x3c03
Apr 29 06:22:42 moghedien rt73: Unstable hardware

Apr 29 06:22:47 moghedien BUG: unable to handle kernel paging request at ffffe800[/code30xicyjp]

And then it starts crashing again, so removing CONFIG_SMP didn't solve the crash issue.

After that my whole ifconfig/iwconfig system is terrible broken. Calling "iwconfig" results in a seg-fault (!!) and when trying to bring the NICs down the kernel hocks up at shutdown, unable to proceed.


Attached the debug.gz.

BTW when modprobe'in rt73 the LEDs on stick remain dumb silent. No flashing, no blinking, no nothing ... I guess they should do *something* ...


30-04-2008 09:05:46

Yikes! Got it! shock

It ain't a kernel/driver issue!

The missing blinking of the LEDs made me suspicious. See it's an old Dell C600 which just supports USB 1.1. Therefore I got an PCMCIA Card enabling USB 2.0 for this laptop.

Now, plugging in the stick works, and the kernel detects the stick well. However, power supply is way too insufficient to let the WLAN Stick perform *full* operation.

After I grabbed an active USB Hub which has its own power supply the WLAN stick got enough energy when connected to the Hub, which in turn was connected to the laptop. The LEDs were blinking like on a christmas show, the rt73 driver loaded, got a MAC and I was instantly connected!!! oops

Though ... the kernel/driver combination really messed up my 2.6.25 if the stick malfunctioned, but well ...

It works now!

Thank you, Vern, for your patience.

PS Errr ..... the board changed since my last visit ... uhm ... is there some "[solved]" prefix button/switch arround?


30-04-2008 20:32:31

Hi dyle71,

Your discovery re. power requirements is good information.

FWIW, I think the driver should work with USB 1.1. I think available power is the pacing requirement.

Good detective work! It seems if I ignore problems long enough, they fix themselves.



01-05-2008 05:47:34

[quote3azb6wqv]FWIW, I think the driver should work with USB 1.1.[/quote3azb6wqv]
Yep, maybe. But the stick doesn't [url3azb6wqv]http://www.dlink.de/?go=jN7uAYLx/oIJaWVUDLYZU93ygJVYLelXSNvhLPG3yV3oUo99haltbNlwaaRp6zsoAmu5j3cf/YEOBM7i36XpLE0WuOzR[/url3azb6wqv]

For linux kernel 2.6.25. can you try this one.
last night, i try to use rt73 module from k2wrlz and I've ported to kernel 2.6.25. Due to nature of this module, it will never up, I think. Maybe, because of the interface doesn't has a MAC address before ifup and it can't be triggered with ifup/usb_rtusb_open() before a MAC address is assigned. So, I've changed the flow of the module and you can refer here.
