Error, dhcpStart: ioctl SIOCSIFFLAGS: No such file or direct

Hey, I am using a Linksys WPC54GS card and when I try

# dhcpcd wlan0
Error, dhcpStart: ioctl SIOCSIFFLAGS: No such file or directory

Anywhere I've gone they either say that the driver is broken or the kernel doesnt have it built in. I updated the kernel a while ago, and it was working before the update, and I am using the same driver, but I dont know what else I could build into the kernel that would make it right.

/usr/src/linux/.config:

hi! I think I know what your problem might be. You updated the kernel sources, and broke compatibility with your out-of-kernel-sources (externally provided, i mean) modules such as ndiswrapper. Try rebuilding them, that may well be your problem. If you have any other externally provided modules you may need to rebuild them too. But start with ndiswrapper.

I had this problem a bit ago. I was really worried about my wireless AP until I realized that all i needed to do was sync up the madwifi package with my kernel. Then, the problem 'magically' disappeared.

That would make sense, but since the kernel update I have actually done

# emerge -e world

because a bunch of other things broke. This still isnt working though.

I'll try anyway though.

nope... still get the same error message.

emerge -e world isn't going to recompile kernel i don't think.

right... but that's not what you said... I already recompiled the kernel, and after doing so, I have done the emerge -e world.

oh, right. sorry, i guess i was confused.

I guess it must be some config in your kernel. You could compare the two configurations i guess...

heh, here's the problem with that... i stupidly deleted the old kernel config. and also I posted the config for the wireless cards, and I have all card possibilities enabled, at least the ones in that section of the config. There's got to be something else that I'm not aware of.

Try upgrading to dhcpcd-3

It may not work but you should get a better error message (hopefully)

Could it be neither the kernel nor wifi driver, but something else? pcmcia-cs maybe?

dhcpcd-3.0.9 gives the exact same error message.

I think my pcmcia is working fine because ndiswrapper -l outputs this:

lsbcmnds : driver installed
device (14E4:4318) present

are all the modules loaded?

wow... I'm brilliant... no... ndiswrapper is not... how do I get it to load at boot again?

Googling implies that although the driver is fine, there is a problem loading the firmware for your card. Check your logs for any firmware related errors.

well, when the module is loaded, dhcpcd wlan0 gives me another error... but I understand and can handle this one

Error, wlan0: dhcpcd already running (/var/run/dhcpcd-wlan0.pid)

So that seems to have been the problem. I also realized why I thought it was running. I had ndiswrapper in /etc/modules which is incorrect. However, it doesnt seem to work properly with it in /etc/modules.autoload.d/kernel-2.6 either. It loads but for some reason dhcpcd wlan0 gives me the same error, I decided I would try the ndiswrapper -m that supposedly makes it so it loads every time wlan0 is called. We shall see...

well... that didn't work either... oh well at least I know what the problem was now

you know more than that my friend. is this akin to the error message displayed prominently at the console?

flamingpi6C73 · n00b Joined: 26 Sep 2006 Posts: 50

yes, however I would still like to get ndiswrapper working at boot... I have tried a number of things, and none of them work. I have to run modprobe ndiswrapper to get it working even though lsmod shows that ndiswrapper is running.

So, the module gets loaded at boot. But either it isn't getting loaded properly, or maybe the module is fine and the device just needs to be started with something analogous to /etc/init.d/net.wlan0 start ?

Ok... so apparently that was not entirely the problem...

nope. guess not.

maybe it's time to move on to

ok, well the newest version of udev still gives the same error.
