I posted this awhile ago and got several views but absolutely no response. Anyone have a clue what's going on? I called Technical support and all they said was if it detects anything in the area with a wireless signal, it will come on. Not buying it;  I have had my Motorola NVG510 gateway for about 3 weeks. I just noticed that when my computer is off and my Nintendo WII is off (I also have standby mode turned off) that my wireless light on the modem comes on by itself occassionally and stays on.  This never happened with my old 2Wire. Does the NVG510 check for updates at certain times, or should I be concerned that someone else is accessing my gateway to use my internet service...or worse. How can I change my encryption on my gateway? I have found no webpage for doing so like I had with my 2Wire.

Any info is appreciated. I have heard how people can hack into others wireless because it always broadcasts a signal when it is on.
