I'm about to have the same problem with a wireless card as we are installing a wireless netword next week. I hope you've solved your dilemma before then but, if not, misery loves company.
About orientation, I'm also a newbie, but my brother told me something about executing commands that helped. He said that files are not ever manipulated as such unless in the context of a particular program.
For e.g., an MS Word file is always manipulated in the .doc format in windows or not at all.
This was significant to me b/c, in Windows, the operating system recognizes the formats so transparently that its easy to forget that there's a program involved in the process.
From the command line, this is a different ballgame. Generally speaking, files do not seem to be manipulated AT ALL unless as part of a command. So the user always enters commands linked to "targets" which are files. The command cues the format of the file so that it is recognized.
This is a small insight perhaps, but it hit me like a rocket. Apologies if its too far from where you are now to be helpful --- but I hope it is.
