I am reposting this earlier from comp.os.linux.networking as I am running
out
of time to fix this.
-------------------------------------------
I have Redhat 2.4.20-28.9 and DLINK PCI wireless card ( DWL-520 ).
Initially RDHT 9.0 with kernel 2.4.20-6 was installed in system ((P3)
Gateway 2000).
Subsequently system updated to kernel.2.4.20-28.9.rpm so that the wlan
drivers
would be compatible with the kernel.

To detect the pci NIC I have loaded the following RPMS
kernel-wlan-ng-usb-0.2.1-pre14
kernel-wlan-ng-0.2.1-pre14
kernel-wlan-ng-modules-rh9.28-0.2.1-pre14

During booting I get
Unresolved symbols in
p80211.o
prism2_pci.o
prism2_plx.o
prism2_cs.o
prism2_usb.o


Also lsmod does not list any prism_* modules or p80211 module.

Looking forward to some help.

Thanks,
-Joydeep

My wireless card works on Redhat linux now.



Here are the conclusions of my investigations

First the DLINK DWL-520 is not expected to work on motherboard

where pci version is not 2.2 or later.



I had to use Vantec Go 2.0 PCI USB wireless card instead because

It was compatible with pci 2.1 of my motherboard.



First rebuild your kernel and boot with it because linux-wlan-ng-0.2.1

driver expects the path to the source code of the currently running kernel.

Then make sure the vendor id and product id is present in the linux-wlan-ng

Source code if not modify



linux-wlan-ng-0.2.1-pre9/src/prism2/driver/prism2sta.c

at around line 450 to 455 to add the following

static struct usb_device_id usb_prism_tbl[] = {

{PRISM_USB_DEVICE(0xyourvendorid, 0xyourproductid, "Your
vendor info")},



Now follow the README that comes with the driver.



Make sure the SSID in /etc/wlan/wlan.cfg and channel # in
/etc/wlan/wlancfg-SSID

is correct and matches your wireless network or WaccessPoint node's SSID.
