无线网卡安装求助！

xbtan

买了一台compaq的笔记本，cpu是celeron m的，安装ubuntu后系统没有找到无线网卡，内核已经升级为2.6.12-10-686，在网上查了一下，应该是用ipw2200的驱动，但是按照http://ipw2200.sourceforge.net/I ... ��到最后modprobe ipw2200以后，没有发现出现新的网络接口，用dmesg查看，ipw2200和ieee80211应该是安装好的。请问应该如何解决？

谢谢！

Make sure your firmware files can be found by the kernel module.
I don't have a ipw2200 card, i have a DWL-650+
when i was installing the driver, a kernel module, manually, I could specify a location when compiling.
However, the same driver come with a Ubuntu linux kernel will look  for the firmware in a different place, and I dont how to change the default path. I think it could be done by passing a parameter to it when running the  modprobe command.

Also, beware of that the module will look for the firmware files with the kernel version as their surfixes. eg, for the module in /lib/2.6.12-10-386, it would look for the file FIRMWARE-2.6.12-10-386 not FIRMWARE-2.6.12-11-686 or whatsoever. It always behave like this if the module come with Ubuntu kernel image.

How can I make sure I put the firmware files in the correct directory?
I put the firmware files into all the folders specified by FIRMWARE_DIRS in /etc/hotplug/firmware.agent.

I install the ipw2200 and ieee80211 by "make" and "make install", I think it would not make a mistake.

btw: the firmware files and firmware directory both have no surfixes.

What does dmesg say about the module ipw2200?
Should be some clue there
