Ubiquiti Amplifi Mesh Router
I have a noob question (I don't know anything about network technology). I have this device in operation and am basically VERY satisfied with it. My topology actually looks like this: Salt router (WLAN off) --> Ubiquiti Amplifi --> End devices (SmartTV, AppleTV, AV receiver). In addition, I had a NAS (WD Live Duo, older device) on the AP - however, I could not access the media in the NAS via app on smart devices (e.g. iPhone) (via PC and WLAN, however, access without problems) --> so NAS to the Salt router and NAS access without restrictions. So side question: Why was that? Actual question: Do I have to set up Salt --> AP --> end devices or could I also Salt --> Switch --> AP and end devices ... my point is that Airplay works and for that I have to be on the same network, right? Or can/must I "manage" something so that the network is one and the same? Thanks for the help in advance and greetings Patjaselm
