Yes, I have two Airport Expresses which I use to stream music, and they extend a Netgear "Orbi" system. But I was not able to get an Airport Extreme to work as an extender, and it was causing problems even when connected via ethernet to my router, so I had to ditch it.I’m curious if it’s possible to continue using an Airport Express to extend a non-Airport network. I currently have a Time Capsule as my router but could use the router feature on my cable modem (currently in bridge mode). However, I’d like to be able to use AirPlay. I’ve done some research and, at this point, am confused. Clarification would be appreciated, particularly from folks who have actually done this (or tried it).
