Wireless Help

I've been trying for about a week to figure this out on my own but I keep running into issues.
I have gotten it to the point of getting a "done" output from netcfg2 but I am still not pinging anything.
I'm not sure what this means.

Can someone take a look at my configs and tell me if anything needs changing?
Thanks!
(I'm running arch with wmii as my WM. I also have xfce installed as a DE for another user if that matters...)

...and it isn't working.

Before I got to this point I have had so many errors: DHCP lease attempt failed (installed dhclient?), Association failed (disabled WPA for now), and it seems that iwlist scan only works after i attempt to connect to a network (what does this say about my setup?)

Please help me sort this out!
If you need anything else just ask...

Thanks

Re: Wireless Help

What if you rule out all other setups, rc.conf, netcg2, networkmanager, dhclient, etc... so nothing is left automated.
And then try to set things up manually first.
So for example, right after boot:

ifconfig wlan0 up
iwlist wlan0 scanning
iwconfig wlan0 essid "drahtlosnetz"
dhcpcd wlan0

Try to use dhcpcd in stead of dhclient, if you don't have it already install it with "pacman -S dhcpcd"

Once you got you network running you can try setting up an automated device, and see if you can get that to work too...
Just how I get things working everytime... hope it can help you.

After a fresh boot...

Re: Wireless Help

Good approach ibendiben.
I'm a noob, but if iwlist fails ("No scan results"), then there's not much use in assigning essid "drahtlosnetzwerk" to wlan0. Try to find out why you're not getting a signal first... Does the access point really work? If it is a laptop, have you tried pressing the Wireless-LAN button?

Re: Wireless Help

I'm on a thinkpad T30 2367. There isn't an on button for it on the case as far as I can tell.
iwlist scan works if I try to connect to a network first. I get several networks that are in range.

What do you mean by "if I try to connect to a network first?"

What happens if you perform the other steps (iwconfig, dhcpcd) now?

Re: Wireless Help

You do not happen to use some kind of encryption do you?
Can you tell me what this wifi0 interface is?
Your error is a very strange one, for what I found. I had it too when setting up my network. But then sometimes it would just work.
And once I finally got it working, it wouldn't fail on me again, so there's hope wink

Re: Wireless Help

another thing is this wpa encryption?  if you are using that, youll need the wpa supplicant as well.  I'd be curious what happens if you do what ibendiben says and do an iwconfig wifi0 essid networkid, then do a dhcpcd?  What kind of device is this wifi?  on my bcm card, even though it showed up, it didnt want to start up right unless i modified the rc.conf to include the ndiswrapper module at boot.... details please?  lsusb, lspci?

Thanks

What do you mean by "if I try to connect to a network first?"

I netcfg2 mom_dads. It outputs done. Then I can iwlist and it scans perfectly. I tried a iwconf......etc...etc. and no go. I like the idea of manually connecting first; I went through my rc.conf and made some changes to accomodate that approach... tell me if my networking and daemon matrices are legit. Thanks for your help so far guys. Good Ideas. Thanks!

Re: Wireless Help

im sorry...maybe its the glass of wine i had tonight, maybe im crazy but earlier your iwconfig shows two wireless devices...wifi0 and wlan0  what are these two devices and why cant you use the wlan0 device with the above commands?

Re: Wireless Help

I tried earlier in this thread. Now, after changing my rc.conf, I get:

[root@Kara wmccann]# ifconfig wlan0 up
[root@Kara wmccann]# iwlist wlan0 scanning
wlan0     No scan results

[root@Kara wmccann]# iwconfig wlan0 essid "drahtlosnetz"
[root@Kara wmccann]# dhcpcd wlan0

Re: Wireless Help

Run /etc/rc.d/dhpcd stop and try the above commands again.   Dhcpd is running already cause you have it in your rc.conf, but netcfg calls it when selecting a profile if set to dhcp (IP=dhcp) which you do.  So you might want to remove the wlan0 from your rc.conf and just use netcfg2.

Re: Wireless Help

Dhcpcd isn't in the rc.d. I have tried letting netcfg2 run the show before but to no avail.

#   - prefix a daemon with a ! to disable it
#   - prefix a daemon with a @ to start it up in the background
#
DAEMONS=(syslog-ng !network netfs crond alsa slim !net-profiles)

To sum up:
- comment all lines declaring interfaces or dhcp,
- comment the "gataway=("-line when you use dhcp this line should always be commented
- prefix the network deamon with a ! to disable it.

Now you perform the steps I told you earlier. See what happens then.
Succes!

If dhcpcd reports to be running already you can stop it with:
dhcpcd -x wlan0
