I have an airport card in my iMac G4 lampshade and it no longer connects to my Airport wifi, not because of a defect or issue but because the only format is just not compatible with the newer. Not sure if there is a work around for that or if using a non Apple wifi router will work but it is something I would think about to make sure it will do what you want it to do.
If you are neutral in situations of injustice, you have chosen the side of the oppressor. If an elephant has its foot on the tail of a mouse and you say that you are neutral, the mouse will not appreciate your neutrality. Bishop Desmond Tutu
