NetworkManager

Just start hacking around with NetworkManager, and realized this plug & play application is not a simple one. Insdie NetworkManager it will call wpa_supplicant, and it will go back to a generic Linux wireless extension (wext). However now every driver able to accept wext, so some specific driver wext will be needed to handle some not so generic driver e.g. madwifi, ralink etc. At the same time, wpa need to get info from hal sysfs to get extension to be pickup or else it will not able to auto-pickup. So the driver itself need to be hal/sysfs enable.
Of course in a good day when the driver is good, we all happy and everything work like a charm, however when you get a buggy driver that's where the nightmare begin. And debugging hal is not a easy one if you don't understand the arch of it function. After all this is a very interesting technology in Linux desktop nowaday.
