I just bought 2 ERA 100s.  One set up easy and works.  The other does not.  I live in apt where I dont control router settings.  I turned off my android phone vpn to try and set up.  It has gotten all the way to asking for wifi network and password which goes fine and then it says it has a problem connecting to network?  how so, if the first era 100 did fine?  I have no other sonos equipment.  how to fix.  Ive reset era 100 and router 5 or more times.  Lights go out after 20 sec on era 100, why is that?  Used to be such a simple product to use, now im debating whether its worth it.  would like some good tips to correct.
