I have posted this in the networking section, but got no reply after one day. Maybe there are more helpers in this section.

I have a PCi GW-NS11H Wireless LAN PC Card, running RH9, I followed what's said in http://www.oreillynet.com/cs/weblog/view/wlg/2318

I installed kernel-wlan-ng-0.2.0-7.i686.rpm, kernel-wlan-ng-pcmcia-0.2.0-7.i686.rpm and kernel-wlan-ng-modules-rh9.20.19-0.2.0-7.i686.rpm which all match my kerel (2.4.20-19.9). Because I don't find my card in /etc/pcmcia/wlan-ng.conf, I added
card "PLANEX", "GW-NS11H Wireless LAN PC Card", "", ""
manfid 0x14ea, 0xb001
bind "prism2_cs"

according to the output from

code:/sbin/cardctl ident

which gives:
Socket 0:
product info: "PLANEX", "GW-NS11H Wireless LAN PC Card", "", ""
manfid: 0x14ea, 0xb001
function: 6 (network)

Then I changed the ONBOOT to yes in /etc/sysconfig/network-scripts/ifcfg-wlan0. Finally I did a /etc/init.d/network restart, but it complained:

Bringing up interface eth0: [ OK ]
Bringing up interface wlan0: prism2_cs device wlan0 does not seem to be present, delaying initialization.
[FAILED]

Apparently, my wlan0 was not bound to the device. I have "alias wlan0 prism2_cs" in /etc/modules.conf.

What other information do I need to provide? I really can't figure out what's going on. I am very grateful for any helps. Thanks.

I found out that the ifcfg-wlan0 was not configured correctly.
The TYPE=Ethernet should be TYPE=Wireless, rite? And the network 192.168.0.0 should be 192.168.1.0, rite? coz ifconfig gives:

ifcfg-wlan0 file:

BROADCAST=192.168.0.255
GATEWAYDEV=wlan0 # this is for setting default route

Any ideas?

When I inserted the card, I found the log message in /var/log/messages:

Aug 16 22:11:28 localhost su(pam_unix)[4738]: session opened for user root by ray(uid=500)
Aug 16 22:11:38 localhost kernel: spurious 8259A interrupt: IRQ7.

Aug 16 22:11:39 localhost cardmgr[3804]: manfid: 0x14ea, 0xb001 function: 6 (network)


Does that mean my card is not supported? But it's using a prism 3 chipset.

PS. My PCMCIA is a cardbus, does that have anything to do with my failure?

Yoyoyoyoyo, GUYS. My PLANEX (PCi) GW-NS11H Wireless card is working now. Will try WEP later on.
I played with the settings for many hours. And I solved the problem, I think, by just these two simple steps.
1. 2. Add the following entry into /etc/pcmcia/wlan-ng.conf

card "PLANEX GW-NS11H Wireless LAN PC Card"
version "PLANEX", "GW-NS11H Wireless LAN PC Card"
manfid 0x14ea, 0xb001
bind "prism2_cs"

The info I got it from Then I used the info to imitate an entry into the wlan-ng.conf.
