I just got my airport extreme cards today and installed them fine. I have networked them but the signal is stupidly low. I am only a couple of feet from the machine i am connecting to and i only have 1 or 2 notches on my airport meter. Will a airport basestation improve my signal becuase i am thinking of buying one of them. Also when i was installing the lead in my g5 there was 2 arial leads inside. One is the same as the one in my powerbook and the other is something else? Also it says in my powermac g5 manual that i should attach an arial to the back of my g5, but i have lost this arial. If anyone can help me with this it would be much appreciated!!!!!!
