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.
