I have heard that this WLAN card works perfect in OS X, however I am also wondering if the same is true for Linux? I am using openSuse. I hate messing around with that madwifi nonsense and if this will solve both my problems I'm sold. Also is there anyway of installing this card without voiding the warranty (like in the expansions slot)? Lastly, has anyone noticed an improvement with signal quality and or speed with this card?
