Tam,
I used the first method in the instructions (iOS AirPlay) to set my AA up, which forced it to connect to my network. Do you know anyone who has an iPhone 5 or 6 who is local? Maybe ask them to come over real quick and see if they can stream to the AA using AirPlay. This will force the unit to connect to your network. I know it's not the preferred method, but it would be interesting to see if this method temporarily works to get your AA connected to your network. If it doesn't then there is something different about your network and my network.
