I have an Airport Extreme and Express. There's a MacBook Pro, MacBook, and PowerBook G4 that connect to it (all 10.5.3, and have the latest 5.3.2 Airport Utility installed). The firmware on the two Airports are both up to date also. There are other gadgets that connect to them, such as 2 iPhones, Wii, 360. Recently, I find that Airport Utility automatically launches randomly about once a day. I'll find this to be the case when I wake up in the morning, when I come home from work, etc. Besides the Airport Utility being launched, everything else seems to be normal. Although I highly doubted it, I thought maybe it's an intruder being malicious with my network, so I changed the passwords and names of the the SSIDs, and also made them invisible. That was yesterday morning, and this morning Airport Utility was launched again when I woke up. Anyone have a clue as to what is going on? Please help!
