halo...i am using fedora core 4, 2.6.11-1.1369_FC4stk.16 ( after change to 16K stack size) and did installed ndiswrapper-1.23 into my distro.
I did followed the installation method from this link:
http://ndiswrapper.sourceforge.net/m...p/Installation

Everything is work fine, and i also did "ndiswrapper -m" to create aliasing to modprobe.conf and also disable irq
by typing "acpi=noirq" in terminal.

I did not have any problem when typing the commands:
iwconfig,iwlist wlan0 scan,ifconfig.

But when i try to activate my network card by typing "ifconfig wlan0 up", the error message shown as:
" No such device".

DId anyone know why ???

It sounds like your driver is loaded but you have not configured your network on wlan0. You can do that from the command line with:

# iwconfig wlan0 essid <insert essid name>
# iwconfig wlan0 key <insert WEP hex key> (if you use WEP)
# dhclient wlan0

If you are not using a WEP key, skip the second command. If you are using wpa, you need to install wpa supplicant to use it and even there, ndiswrapper often has problems with wpa. The best thing is turn all encryption off on your wireless access point and see if you can get connected. Then try wep 64 bit, wep 128 bit and wpa in that order.

halo..may i know what is wpa ???
I did followed the instruction from your previous messages, and it shown as below:

[root@localhost kokchin]# iwconfig wlan0 essid 'WaveLAN Network'
[root@localhost kokchin]# dhclient wlan0
dhclient(3472) is already running - exiting.

Or i explained in details what I did by following the instruction installation of the link from my previous message.

after i intsalled the ndiswrapper and window driver, and it shown hardware exist and driver installed. Then i type " dmesg" :

((maybe i did typed some command such as iwconfig,iwlist,ifconfig and ifup ...then it appears the extra message such as:

ndiswrapper (set_encr_mode:689): setting encryption mode to 6 failed (C00000BB)
ndiswrapper (iw_set_bitrate:508): setting bit rate failed (C0010017)

ndiswrapper (ndis_open:770): couldn't set packet filter ))


Then i checked the wlan0 interface whether got exist :

[root@localhost kokchin]# iwconfig
lo no wireless extensions.

eth0 no wireless extensions.

sit0 no wireless extensions.

Then i typed "iwconfig wlan0 mode Managed" , then is ok.
Then i typed "iwconfig wlan0 essid "WaveLAN Network", then is ok.
Then i checked the essid whether is the name of "WaveLAN Network", it shown:

Below are my details of /etc/sysconfig/network-scripts/ifcfg-wlan0 files:

# Please read /usr/share/doc/initscripts-*/sysconfig.txt
# for the documentation of these parameters.
IPV6INIT=no
ONBOOT=no
USERCTL=no
PEERDNS=yes
GATEWAY=
TYPE=Wireless
DEVICE=wlan0
HWADDR=00:0c:f1:31:f6:af
BOOTPROTO=dhcp
NETMASK=
DHCP_HOSTNAME=
IPADDR=
DOMAIN=
ESSID='WaveLAN Network'
CHANNEL=1
MODE=Managed
RATE=Auto


I did set the "ONBOOT = yes " , but it still cannot connect to internet.
I did typed "acpi=noirq" to disable ACPI , as taught in this link:

http://ndiswrapper.sourceforge.net/m.../index.php/FAQ

I did refer to 2 links below:

http://ndiswrapper.sourceforge.net/m...roubleshooting
http://ndiswrapper.sourceforge.net/m...roubleshooting

But still have face the same problem.
Did anyone have any ideas about this problem ??
I did really running out of ideas why still cannot connect to internet.
Please drop your advices and ideas here. Your advices are much appreciated.

WPA is a type of strong encryption that is replacing WEP which can be pretty easily cracked.

For your ifcfg-wlan0 try something simple like this:

DEVICE=wlan0
BOOTPROTO=dhcp
ONBOOT=no
HWADDR=00:0c:f1:31:f6:af
METRIC=10
MII_NOT_SUPPORTED=yes
WIRELESS_MODE=Managed
WIRELESS_ESSID=WaveLAN Network

You only need the HWADDR line if your wireless router has MAC filtering turned on and if that is the case, you need to add your wireless MAC to the allowed list of MACs. Also, I don't believe there should be any quotes around the ESSID name. I think you're pretty close to getting this working; just need to get the configuration right.
Finally, if you are dual booting with windows, confirm that wireless is working OK in windows.

actually i trying to connect to internet through wireless in library, if I want to use WEP or WPA, is that i need to get the key from wireless host library or is can set by myself ??

It's unlikely that a library would use any form of encryption but you should ask the librarian. Libraries around here tend to be open networks that can be accessed for free. They certainly aren't using any MAC filtering.

I did able to connect to internet through Window by setting in all "auto mode", is that possible I need to set the encryption key for WEP or WPA to connect wireless to internet in fedora by using ndiswrapper ??

If you can connect through windows, it's an open network. You cannot connect to a wireless WEP or WPA encrypted network without the key which would have to be given to you by the library. Try the ifcfg-wlan0 I gave you and see if it works.

halo kilgoretrout,

I still not able to activate my wlan0 interface after follow your instruction by changing the setting of ifcfg-wlan0 at /etc/sysconfig/network-srcipts/.

One thing i feel weird is if i am not able to activate my wlan0 interface, how can my wlan0 interface scan the access point in library ?

I knew my wlan0 interface is not activated when i typed "ifconfig" , there is not wlan0 interface appear, just loop back interface and ethernet interface(wired connection). Besides that, when i tried the commmand "ifconfig wlan0 up", it shown that no such device. Then, i tried "ifup wlan0" , it shown faied to determine IP.


Did anyone have face similar condition as me ??
Please drop your message here if you have any ideas...Thanks!!

I was just having the same problem with an rtl8180 card. When you ndiswrapper -l, does it show the driver as installed AND hardware detected? That's where my problem was; my hardware was not being detected because the wrong driver was installed. Actually, it was the right driver, but it had to be hacked before it worked, but that is neither here nor there (unless, of course, you are using this driver as well; if so, check out this website, my card was #11).

EDIT: Uh, it won't let me post the website since i don't have 3 posts yet. Email me and I'll send it to you if needed.

when i typed ndiswrapper -l , my hardware is exist and type "dmesg"...everything is ok as shown from the terminal. i did "ndiswrapper -m" and also "apci=noirq" as stated in ndiswrapper FAQ.

I just curious if my cannot activate my wlan0 interface, why i can scan my access point in library ??

I did stated from my last post message.
If anyone know about it please post your ideas here. Thanks a lot

Thanks to kilgoretrout first, thx for your advices and suggestions to me even though it not help me to get wireless connection successfully.

finally i can connect to internet through wireless. I did changed to use older version of ndiswrapper, whcih is ndiswrapper-1.1

Now i know the reason why i cannot connect to wireless connection. This is because the wireless tool version cause me cannot connect to internet through wireless althought i seem like able to scan my library access point.
You can see the error message like this from my previous messages :

Warning: Driver for device wlan0 recommend version 18 of Wireless Extension,
but has been compiled with version 17, therefore some driver features
may not be available...

I am not sure how to install the latest version of wireless tools. It seem like need to recompile the kernel if i am not mistaken. If anyone know how to upgrade the wireless tool version please let me know it .Thanks a lot.
