I have an Airport Extreme with private and guest network, plus a wired Airport Express extending the reach of the private network (plus streaming music). All works nicely, except that the guest network reach does not get extended. This is unfortunate, but given that the Express is an older product it is not too surprising.
Question: If I add a 2nd wired Airport Express next to the existing one, can it be configured to extend the guest network? That is, there will be two Airport Express each extending a separate network?
