Ok, I'm a new mac user. And I used to turn on my computer and it would connect to my home's WiFi right away. Now, the airport is on, and it won't connect to it unless I select the router (which it sees right off the bat..) or if I turn the Airport Off and then back On. There are 2 ways this could have happened: A) I screwed with some setting that I shouldn't have. B) When my computer had a WiFi related Kernel Panic during sleep near 0% battery life. Basically I'm trying to avoid reinstalling OS X (again....). So if anyone has any idea what to do, please help (Apples support documents were of no help). Thanks.
