Wireless device support — and indeed, wireless reliability — has been frankly awful in Linux up to this point. Even among the devices that work (at least some of the time), there are frequent problems. For example, my IBM Thinkpad T42 laptop comes with an IPW2200BG adapter that mostly works — except after suspend, when it will refuse to function unless the driver is unloaded and reloaded. I’m using NetworkManager to "magically" manage my network connection; when it works, it works fabulously, but there are no docs. None. I challenge you to try and find a man page or any scrap of documentation about NetworkManager anywhere on the Internet.
At least on the driver side there might be some hope on the horizon. Devicescape, a WiFi software stack specialist, has just released their "Advanced Datapath" IEEE 802.11 driver stack under an open source license, and several kernel developers are trying to get it integrated into the Linux kernel. Of course, as with all integrations, this won’t happen overnight, but when it does, many wireless features such as WPA, WEP, software MAC, and so on that currently require add-ons like the userland
wpa_supplicant for WPA could be directly run by this stack.
I’m looking forward to the day when I don’t have to do this magic incantation to get wireless working after suspend:
# /etc/init.d/NetworkManager stop
# /sbin/modprobe -r ipw2200
# /sbin/modprobe ipw2200
# sleep 10
# /etc/init.d/NetworkManager start
A complete non-sequitur: survey questions that make no sense.
would like to take the opportunity and say i learn a lot on this page, and i am still laughing pretty hard at survey question #13. suppose the answer should be "n/a", though if one chooses any other, the reply says one of these: "excellently quickly", "quickly good" (since "goodly" can't work), "averagely quickly" and so on…i'm just amusing myself there a little bit.
I also have no idea why "N/A" is a checkbox, whereas the others are mutually-exclusive radio buttons. A valid, though meaningless, answer would be "Excellent N/A" — but then again, "Excellent" is meaningless as a response to "How quickly…" anyway.
You could start writing the NetworkManager docs. You obviously know something about the program, and there are currently no docs available. I encourage you to write something and submit it to the NetworkManager devs, or just post it online.
This is how free software works, the more everyone contributes, the better it will work for all of us.
