Mark,
Here's what I got when I typed those three commands:
The wlan-card is not among it, correct. Beside that, there is no clue in there what goes wrong.
ndiwrapper is loaded when I type lsmod, but the system does not seem to recognize the wlan card still.
Okay. So there seems to be a few problems left :( What I did up to now: I went at www.google.com/linux and searched for "dell 1450 wlan". I got quite some results and reading some of them, I get the impression that it should work. Please have a look at the results of this google-search too. In the meantime: Did you installed the sources of the kernel (package "kernel-source<version>)? And what is the output of the following command: $ lspci (launched as root!)? We should get the exact name of the included wlan-device. Sometimes. producers change their included components without mentioning it anywhere. Greets, Dennis
