i am sure this is on the forum... but i couldn't make sense of the aiport/ intel thread as it has all these complicated numbers on it, so sorry if this is the umpteenth time you have read a simlar post... Anyways, my macbook has developed a bad habit of not picking up MY wifi signal in the last week. Everytime it wakes it it wants to jump onto a non password protected network, and I can only use my own if i redo the whole name of network/ password thing in internet connect. is there a firmware for this? i am also hesitating to download 10.4.7 just incase everything gets worse. Thanks a bunch!
