D-link DWL-122无线网卡厂家没有提供Linux下的驱动，只有Windows下的驱动，我应该怎么办使得此无线网卡能在Linux下用啊？自己写驱动有没有设备的具体资料。谢谢大家了。 :D

先用lsusb看你得卡得芯片，然后到
http://sourceforge.net/projects/ndiswrapper/
看看你得卡是否被支持，如果支持，用ndiswrapper+winxp网卡驱动就可以用了。
不过这个东东好像对pci和pcmcia的卡支持的比较好，usb的不知道怎么样。

谢谢，我的卡支持。但内核版本不够，我是2.4.XX。

You can configure a new kernel.

碰巧俺用的就是这块usb的无线网卡，look this，当时俺参考的就是这个。
D-Link DWL-122 Wireless USB Adapter linux HOWTO      
2003.12.22 @ 8:48:47 PM
I've got a D-Link DWL122 Wireless USB Adapter this weekend for $29.99. Not only the price was good, but it also stated "Mac OSX supported", which sort of encouraged me to go ahead and give it a try.

I asked Mr. Goggle, who told me right away it uses a Prism2 chipset, and that it is supported by linux-wlan-ng version 0.2.1-pre13 or later, thanks to a patch written by Andrew Beresford.

(Gentoo users use "emerge". More info at the end of this document)

Installation was long but smooth. It requires kernel sources and a locally compiled kernel, as any precompiled kernel with sources will cause dependency errors when executing depmod:
/sbin/depmod -a
depmod: *** Unresolved symbols in /lib/modules/2.4.20/net/p80211.o
depmod: *** Unresolved symbols in /lib/modules/2.4.20/usb/prism2_usb.o


I realized it would be rather hard for an inexperienced user to get this device to work. That is the reason why I wanted to write something about it. So here is a quick HOWTO:

- First become root and cd into your src directory:
su -
cd /usr/src


- Get the latest kernel source from www.kernel.org. I used 2.4.23 when I wrote this article, but it also works on 2.6
wget ftp://ftp.kernel.org/pub/linux/kernel/v2.4/linux-2.4.23.tar.bz2




- Uncompress your kernel and make a symlink so that it can be accessible as /usr/src/linux
tar -jxf linux-2.4.23.tar.bz2
rm linux
ln -s linux-2.4.23 linux


- cd into your new kernel and compile it:
make menuconfig (spend a few minutes here configuring your kernel properly, one of the pleasures of opensource)
make dep
make bzImage
make modules
make modules_install
make install
cp arch/i386/boot/bzImage /boot/vmlinuz-2.4.23
cp System.map /boot/System.map-2.4.23


Note for kernel 2.6 users: Install the module-init-tools package, enable on your kernel Device Drivers -> Networking support -> Wireless LAN (non-hamradio) ->

Wireless LAN drivers (non-hamradio) & Wireless Extensions.
And compile your kernel with "make && make modules && make modules_install" instead

- Create the right entries in your bootloader. This instructions will depend on the bootloader and distro you are using. In my case it is GRUB running on Debian, therefore the configuration file is located at /boot/grub/menu.lst. It would be /boot/grub/grub.conf in RedHat and /etc/lilo.conf for LILO users. All you have to do in all cases is create a new section as follows (for lilo users, it is slightly different):
title Linux kernel 2.4.23
root (hd0,0)
kernel /boot/vmlinuz-2.4.23 root=/dev/hda2

(make sure you set the right root parameters, check your existing menu options for clues. Lilo users must now execute lilo)

- Reboot your machine choosing the new kernel and log in as root again.

- Get the latest linux-wlan-ng drivers (0.2.1-pre16 in this case), uncompress and configure as follows:
wget ftp://ftp.linux-wlan.org/pub/linux-wlan-ng/linux-wlan-ng-0.2.1-pre16.tar.gz
tar -zxf linux-wlan-ng-0.2.1-pre16.tar.gz
cd linux-wlan-ng-0.2.1-pre16
./Configure

- Compile and install with:
make all
make install


- That's all. Now you can tail /var/log/messages -f and plug in your Wifi usb adapter. You will see something like this:

- Now you need to configure your network accordingly with your access point. Edit /etc/wlan/wlan.conf and set your SSID as follows:
SSID_wlan0="mywlan"
ENABLE_wlan0=y


- This means you will need a /etc/wlan/wlancfg-mywlan file. You can use the included wlancfg-DEFAULT for reference. You might want to try first with the default configuration, disabling WEP on your access point, but do not forget to enable it once you know it works:
cp /etc/wlan/wlancfg-DEFAULT /etc/wlan/wlancfg-mywlan


Note: When enabling WEP make sure there are NO spaces/tabs after "=" in the line dot11WEPDefaultKey0=00:01.... otherwise it WILL NOT WORK !!!. I have submitted this info, and hopefully will be corrected in future versions.


- Configure now your IP:
ifconfig wlan0 192.168.0.2 netmask 255.255.255.0
route add -net default gw 192.168.0.1


Note: This IP configuration will work with most default configurations. Make sure you set the right local (wlan0) and gateway (gw) ip addresses. You may even have DHCP enabled on your access point, in that case you can obtain your ip automatically with dhclient

Note2: I have just installed Gentoo on my laptop and emerge takes care of evrything. All you have to do is:
USE="usb -pci" emerge linux-wlan-ng

(make sure first that emerge -s linux-wlan-ng shows version 0.2.1-pre13 or later)

Note3: Make sure CONFIG_PACKET and CONFIG_FILTER are enabled in your kernel if you expect DHCP to work.

That should get you going. Enjo
