2 issues.. Sonos seems to have an issue with repeaters.. And Amped seems come up..
Second.. Chromecast does not like Amped wireless repeaters.. So I need to connect directly to to my Asus router..and all works fine.
Not sure if it's a handshakeing issue.. Hoping a asus repeater. Will correct this issue..
Where I live (central Europe), RP-AC52's availability is also very poor. The price comparison tools do list them as available from just a few sellers but the price is c.a. 80% the price of RT-AC56U. I was in similar position (only I wanted it as a wired Access Point, not Wi-Fi repeater) just a few days ago and ended up getting a second router. I am happy with my choice as now I have two full-blown routers and I'm free to shuffle them around, repurpose them both as I wish in the future, etc. The added flexibility is well worth the ~20% price premium being asked for RT-AC56U over RP-AC52, if you ask me. Not to mention the faster theoretical wireless throughput (BTW, do you know this repeater has only a Fast Ethernet port?) and a GbE switch. Well, I kind of miss the night light function, though
