[ltp] HELP: wireless wlan-ng setup problem with T30 on Mandrake 9.0

[Wei Wang]

There have been various reports of successful IBM T30 w/ wlan-ng with 
various distros. (Unfortunately haven't heard a single one on Mandrake yet).

I have Mandrake 9.0 and thinkpad T30 and am trying to make the wireless
care work with wlan-ng 0.1.16-pre8. I've been at this for a week and
just couldn't get it to work.
This is what I've done.

Reconfigure and recompile kernel 2.4.19.(It takes me 50 minutes for the compiling. I don't know what went wrong. But that's another story)

Successful install with "make config", "make all" and "make install"
I've deleted the broken Mandrake 9.0 built-in prism2 driver.

1 modify /etc/rc.local (this is the rc.local to modify, isn't it? there   is another rc.local in /etc/rc.d/
   #modprobe prism2_pci  
   #wlanctl-ng wlan0 lnxreq_ifstate ifstate=enable
   #wlanctl-ng wlan0 lnxreq_autojoin ssid=<w-107-CB2-3QG> authtype=opensystem
   #ifconfig wlan0 <yourIP> netmask <yourNetmask> broadcast <yourBroadcast> route add default gw <yourGateway>

   I am using DHCP and automatic IP and don't know what to put here in    <yourIP> and <yourNetmask>, etc.
2 my resolv.conf reads

nameserver 128.232.1.1
nameserver 128.232.1.2
nameserver 128.232.1.3
search cl.cam.ac.uk


3 I didn't try the rc.wlan alternative. I don't know how to do that. 
  Also the only rc.wlan I could find through locate(w/ very recent updatedb)
  are: 
  home/wei/tarball/linux-wlan-ng-0.1.13/etc/rc.wlan
  /home/wei/linux-wlan-ng-0.1.15/etc/rc.wlan
  /home/wei/linux-wlan-ng-0.1.16-pre8/etc/rc.wlan

  

4 wlan.conf:
	SSID_wlan0="lab"
	ENABLE_wlan0=y

  wlan.cfg-lab:
  I don't know how to modify this file. I have a ESSID and a network key but 
  don't know where to put them in this file.


I guess that's all I need to do, right? 

dmesg after boot gives:

PCI: Found IRQ 11 for device 02:02.0
PCI: Sharing IRQ 11 with 00:1d.2
PCI: Sharing IRQ 11 with 00:1f.1
A Prism2.5 PCI device found, phymem:0xf8000000, irq:11, mem:0xf2f20000

prism2sta_probe_pci: prism2_pci: wlan_setup() failed.
init_module: prism2_pci: No devices found, driver not installed.
p80211.o: 0.1.14 Unloaded

If I do modprobe prism2_pci again I get this error message:

/lib/modules/2.4.19-16mdkhope/kernel/drivers/pcmcia/ds.o: init_module: Operation not permitted
Hint: insmod errors can be caused by incorrect module parameters, including invalid IO or IRQ parameters.
      You may find more information in syslog or the output from dmesg

And this time dmesg reads:

I've been searching google with "wlan_setup: called without wlandev->name set."
but nothing useful came up. 
Does this have anything to do with what I haven't finished in the configuration above(wlan.cfg-lab and rc.local)?


Please help.


Many thanks,
