My wife has a macbook and has had no problem connecting to the internet through our router until now. Our wireless network has always been password protected, but until this weekend she never had to re-enter the password. now she has to re-enter it every time she starts surfing the net. The only change was that she had used a wireless account at her parents house. She has used other wireless accounts (wifi hotspots etc) before and never had this issue. Any thoughts on what the problem might be?
