Intel WiMax/WiFi wireless networking broken in Kubuntu 10.04

Can you give the output of:

sudo lshw -C network; sudo iwlist scan | head -n 15

Thanks

The first "solution" says "wait"; the second says "use ndiswrapper" somehow. What do you recommend, and how do I go about it?

If you need it to work now then ndisgtk is part of a standard install. You will need the windows .sys and .inf file

I installed ndisgtk. When I open /usr/sbin/ndisgtk, it asks for Windows drivers. No drivers are currently selected.

Since I dual-boot this machine, the Windows 7 image is on a mount point called OS. Do I select the files ndiscap.inf and ndisuio.inf in directory OS/Windows/inf? Doing so, the tool marks them as invalid drivers. I didn't get to the .sys files. What am I doing wrong?

Well yes, you should download the XP driver (32bit or 64bit depending on the architecture of your installation)

You can find out the arch using:

uname -m

if the output is "i686" its 32bit, "X86_64" means 64bit

you will need the .inf and .sys files from the driver file, ndisgtk will help you install the files.

uname -m says: x86_64

The other partition to my Kubuntu installation is a Windows 7 installation, and the WiMAX/WiFi works fine there. Should I locate the Windows drivers that are used there, or am I restricted to an XP installation?

When I open sudo ndisgtk, the terminal window reports:
(ndisgtk:2035): libglade-WARNING **: Could not load support for `gnome': libgnome.so: cannot open shared object file: No such file or directory

and the blank "Wireless Network Drivers" window is not much help. Maybe I'll resort to running Windows 7 after all :-(

The XP drivers usually work better but just get some 64bit windows drivers and use them. "restricted to an xp installation" doesn't make any sense here, the fact you have Win7 on another partition is completely moot.

Again, using a wired connection will help here and getting updates will help lots.

Would someone else be able to explain the details of the above procedures more precisely? I appreciate all your insights, but I guess that I'm not as atuned to Linux system administration as I need to be.

Oooooh look what I found:
http://www.linuxwimax.org/Download

I started downloading packages mentioned in this page (i.e. http://www.linuxwimax.org/Download), and thought it would be a good idea to download the GNU C++ compiler too. :-) I've extracted i2400m-fw-1.5.0, wimax-tools-1.4.3 and wimax-1.5 directories, and started to configure wimax-tools-1.4.3.

After setting environment variables LIBNL1_LIBS=/usr/lib, LIBNL1_CFLAGS=" ", GLIB_LIBs=/usr/lib and GLIB_CFLAGS=" ", I was able to convince ./configure --with-i2400m=/usr --with-libnl1=/usr/lib/libnl.so.1.1 to run without errors. But then, running make coughed, spluttered and gave up!

I'm pretty sure that my band-aids did not help the "disease". Any further suggestions would be appreciated.
