Wireless network in KNOPPIX_V3.1-2003-20-EN

**kees** · 02-15-2003, 10:07 PM

I'm having trouble initialising the ESSID of my wireless
networkcard. If I change the ESSID in my router to
"linux-wlan" everything works. So I can get it to work but
I want a different ESSID.

I set the ESSID with the program (MENU->KNOPPIX->Network/Internet->Wavelan configuration)
It initializes a file called '/etc/pcmcia/wireless.opts'
This file is interpreted by the program /etc/pcmcia/wireless.
I managed to track down the command that is executed and
tried it on the command line with the following result :

Code:

SH > iwconfig wlan0 essid hallo
Error for wireless request "Set ESSID" (8B1A) :
SET failed on device wlan0; Function not implemented.

I noticed a Warning when executing iwconfig :

Code:

SH > iwconfig
...
Warning: Driver for device wlan0 has been compiled with version 14
of Wireless extension, while this program is using version 15.
Some things might be broken...
...

Is there something broken ?

I noticed the same and am wondering if there is an easy fix , how does one update the files in /lib the prism2.o files that seem to be broken.
Is it possible to mount /lib rw on the ramdisk or something?

Did this work in earlier versions of Knoppix? Then please send the bug description to Klaus Knopper.

I have gotten a specific ESSID to work, but my methods are very kludgy.

I'm using Knoppix v3.2-2003-05-20 on a Dell notebook with a Linksys AP and an Orinoco Gold card. I also get the version 14 versus 15 mentioned above.

Initial bootup identifies my Orinoco Gold card correctly, but I get no Internet access (wireless card not found). Running iwconfig or netcardconfig and selecting DHCP produces no results.

This is what works for me: Open a shell and run netcardconfig and select STATIC configuration. Enter info from LAN (internal) connection (notebook=192.168.1.100, gateway=192.168.1.1, no DNS). After ifconfig sets the LAN parameters a wireless configuration tool opens up and requests wireless parameters like ESSID and channel and stuff. I enter my specific ESSID and channe number and the program (iwconfig?) writes these parameters. Nothing works yet, but we're almost there.

Rerun netcardconfig again, but select DHCP this time. Sending DHCP broadcast from eth0 is now "OK" and "auto lo eth0" sets everything up. From now on wireless performs correctly with my specific ESSID and channel number.

If I could restore myconfig from a floppy (to save these settings) I'd be a happy camper...

If it's a Prism card, dont't use iwconfig for setting the SSID, but use the following instead:

Code:

 wlanctl-ng wlan0 lnxreq_ifstate ifstate=enable
 wlanctl-ng wlan0 lnxreq_autojoin ssid=SpeedStream authtype=opensystem
 ifup wlan0
 pump -i wlan0

Of course, you should use your own SSID instead of "SpeedStream"

orinoco is not prism based. iwconfig works.

Just sharing my experience with my orinoco silver. All that is needed is the following 2 lines:

#iwconfig eth0 essid "whatever" enc "your WEP key"
#pump

you may put this in the knoppix.sh

thanks a million! your method worked great for me running integrated intel wireless on my dell latitude...

You're welcome. Glad it helped.

After reading an earlier message, I have to say that garyng has a much easier way of setting up a wireless card. I wasn't familiar with the pump command.

Boot the Knoppix CD normally.
#iwconfig eth0 essid "whatever"
#pump

This method is much quicker than what I was doing... especially since I can't save and restore network configurations.
