Description of Issue

After switching to TP-Link Deco Mesh Wifi router, I couldn’t find Roon core with either my Mac or cell phone as Roon Remote. The core may briefly appear and show “connecting” but disappear shortly after. The Roon core PC and all the remotes are in the same network with IP addresses 192.168.68.xx
Everything was working when I was using my old TP-Link regular wireless router.

When you change networks, which is what the new wifi is to a Windows PC, you need to make sure that you replicate all the firewall settings as well, and verify that the network is Private and not Public.

Thanks!
Changing firewall settings solved the problem!
