Google translate: Nucleus+ just arrived yesterday, using Huawei mobile phone P50pro, downloading APK from ROON official website, but the core cannot be found after installation. What I connect is to build a soft router by myself, because mainland China is not friendly to Google and Netflix video sites, so I need to build another router to bypass the wall. The speaker is KEF that supports ROON and is also connected to the soft router.
To simply the network setup, connect both the P50 Pro (via WiFi) and the Nucleus+ to your WiFi router (or WiFi access point). Make sure the WiFi router is passing multicast packets. Consumer grade TP-Link routers usually work.
For Asus router, enable LAN → IPTV → Multicast Routing.
For Netgear, disable Smart Connect. With some models of Netgear, you may need to disable IGMP.
Also look for IGMP settings in the router and experiment with them.
Google translate: Today I changed to the Apple Mini 6, but I still can’t find the core. My soft routing system is openWrt R21.6.1 GDQ v6.1, through linksys3200ACM to connect to the door of China Unicom optical cat to go online. It seems that it has nothing to do with the mobile phone and is mainly a router problem. I don’t know how to operate it.
