Madwifi installed, but no wireless connections found

jasper-2
Well allow me to be clearer on my madwifi installation / functioning problems
the before. I left it for a while but would really get it going this week.

First my computer specs:

Acer Aspire 4520G AMD Turion 1.9 GHz Laptop,
2 GB memory, 160GB Harddisk,
Nvidia GeForce 8400m G 128 MB Graphical card,
 802.11b/g WLAN, Bluetooth.

Linux specs:

Ubuntu Hardy Heron 8.0.4 Linux Kernel 2.6.24-19-generic
Madwifi version: 0.9.4

I had madwifi running before but after a kernel change it didn't work anymore. I
tried to uninstall all and reinstall madwifi again many times, but to no avail.
When I enter iwconfig I get:
lo        no wireless extensions.

eth0      no wireless extensions.


ifconfig gives:

When I entered sudo make in the madwifi directory now I got :
jasper@jasper-laptop:~/Documents/madwifi-0.9.4$ sudo make
[sudo] password for jasper:

Then I entered: sudo modprobe ath_pci
Nothing showed, but I presume this is for activation....

Then I entered:
jasper@jasper-laptop:~/Documents/madwifi-0.9.4$ modinfo ath_pci

and got:

But still I get:

jasper@jasper-laptop:~/Documents/madwifi-0.9.4$ iwconfig
lo        no wireless extensions.

eth0      no wireless extensions.

I hope I have been clearer now. Please tell me what I am missing here... Maybe
it is a network configuration problem, not a madwifi problem?

Maybe you forgot "make install"?  Ubuntu can install its own MadWifi,
which could have been loaded instead of the one you have compiled.

modprobe only work on installed modules.  It doesn't check the current
directory.

modprobe would report fatal errors on the command line.  Messages from
the driver are placed to the kernel log.  The kernel log can be checked
with the dmesg command.  Please look at the log to possible problems.
If you cannot resolve them, please post the end of the log to the list.

If the problem if with unresolved symbols, you'll need to reboot or
unload the original MadWifi modules with madwifi-unload.bash included
with the sources.

All that is only interesting if you look at the lspci output and compare
the ID of your device with the IDs printed by modinfo.  To get enough
information, please port the result of this command:

lspci -vnn -d 168c:

That would list all Atheros devices with their numeric IDs.

Apparently, the device wasn't claimed by the driver.

iwconfig shows all network devices, even if they are down.  No network
configuration problem can hide a wireless device from iwconfig.
