Hello I am writing to see if anybody else encountered this problem. Today recieved my new macbook in the mail and I had been using it all throughout the day and after I performed a software update i turned on my family's pc and after windows loaded up (and connected to my wireless network) i grabbed my mac and I saw that I lost my internet connection and it prompted me to enter in my password. I thought that was wierd b/c I had already entered in my password and told it to remember the connection. Anyways, i reentered my password and after 3-4 seconds i see something that says: "incompatible security." So I disable the wireless internet on the pc and suddenly the macbooks wireless works again (w/ no pword request.) What do I have going on here? Any software updates required? I am stumped!
