A:AnswerThe hex key is supposed to separate the camera and battery from the plastic housing. You insert it, turn to the right, and it "pops" after which the front is supposed to separate from the housing. It does not. Whoever said "easy peasy" must not have had the camera up for long, because it does not pop out easily after it's been up a few weeks. If you're trying to figure it out in your hands on your kitchen table right out of the box, sure, works like a charm. If you're on a ladder on your front porch and it "pops" but doesn't "pop out" you are stuck. Not the only one with this issue.
A:AnswerNo, it will not, at least not easily. The orbi broadcasts dual band wifi, meaning there is no way for you to choose the 2.4ghz band, you just get whatever wifi band is best. Even when you are on the 2.4 ghz band, it still won't connect for no apparent reason. There are numerous questions about this on the arlo community forum with no real resolution.
