Trouble installing a wireless card

HackTidus · 02-11-2008, 06:40 PM

--Using Fedora Core 6--

I currently own a DWL-122 USB (prism 2) wi-fi card which is compatible with the wlan-ng 0.28 drivers (at least, that's what the compatibility list says), i've downloaded the drivers, and run a ./Configure a make and a make install on them, but still don't know how to use it, i've tried to add a new wireless net interface on the net configuration, but the DWL isn't displayed, maybe I missed some steps on the installing process, could someone tell me how to install the drivers and enable the card? It would be a great help...

Thanks in advance!

The card is compatible with the orinoco / orinoco_cs driver which is already part of the kernel, for example;

$ locate orinoco
/lib/modules/2.6.18-53.1.6.el5/kernel/drivers/net/wireless/orinoco.ko
/lib/modules/2.6.18-53.1.6.el5/kernel/drivers/net/wireless/orinoco_cs.ko

You will need to have isl3890 firmware in the /lib/firmware directory, for example;
$ ls -al /lib/firmware/isl3890

Do you know where I could get good working firmware for this? I found a bunch of links to Mac OS X firmware downloads, but all of them had subsequent posts about the downloads not being good.

Since this is a USB interface visit: http://jbnote.free.fr/prism54usb/index.html follow the link;
please manually goto the firmware directory.

dont know much about those drivers, could you give me more exact instructions? i'd be really nice

Thanks in advance?

besides, the prisusb driver is compatible with the DWL-G122, i own the DWL-122 which is a different version

HackTidus · 02-12-2008, 07:52 AM

prism54usb i meant

Then as a suggestion use the Windows XP driver and dkms-ndiswrapper from freshrpms.net;

rpm -ivh http://ftp.freshrpms.net/pub/freshrp....fc.noarch.rpm

yum install dkms-ndiswrapper --enablerepo=freshrpms

thanks, i'll give it a shot and see if it works

i've successfully installed the windows drivers with the version specified, done a modprobe, but it doesn't detect my card on the net interfaces screen, any ideas?

Lenard · 02-12-2008, 12:17 PM

Have you setup the alias in /etc/modprobe.conf?? alias wlan0 ndiswrapper
Do you have a file named ifcfg-wlan0 in the /etc/sysconfig/network-scripts directory???
Example file;

Code:

TYPE=Wireless
DEVICE=wlan0
HWADDR=
BOOTPROTO=dhcp
DHCP_HOSTNAME=
IPADDR=
NETMASK=
DOMAIN=
ONBOOT=yes
USERCTL=yes
IPV6INIT=no
PEERDNS=yes
ESSID=
CHANNEL=
MODE=
RATE=

done the alias thing and seems to work

thank Lenard!

HackTidus · 02-12-2008, 01:12 PM

no, still doesnt work

i see the hardware and i've set up a network interface named wlan0, but when I type iwconfig, doesnt detect any wireless interfaces...

the file you told me before is missing

HackTidus · 02-12-2008, 01:28 PM

i've spotted that file finally, the hardware adress is set to 00:00:00:00:00:00 which doesn't seem quite regular, how can I know my actual hw adress?

Check the var/log/messages file, look for the ndiswrapper lines;
Example;

Code:

It should be listed on the device itself also.
