I have internet on my IPAD. The static IP on my Ipad is 192.168.178.239
And the static IP of my PC is 192.168.178.253
Those numbers are assigned in my dd-wrt router using the mac address
This is how my static internet works: every single device with its own unique mac address has its own static ip
The thing is: while Roon on my IPAd is in the Choose your Roon Core mode it is looking for 192.168.178.2 all the time
Weird is, sometimes in a few seconds it gives 192.168.178.253 and I have to click fast to ok and then I am inside, else it stays on 192.168.178.2 and I can wait forever…
How can I set that 192.168.178.253 is always be used by Roon?
I don’t think you can, the iPad is does a discovery process to look for the core, and it’s usually pretty close to instantaneous. I don’t know why you feel you need to use static addressing, it just makes more work.
A static IP makes a home network more stable then DHCP. But I think for me a crucial option is missing: selecting the network settings where roon has to search the main server and in my opinion it is really embarrasing Roon does not have such a tool build inside the app. The only way is to buy a separate laptop where I can save the core.
Roon uses multicast for discovery, so I would take a look at your DDWRT router and make sure that multicast is active and perhaps try toggling IGMP Proxying/IGMP Snooping, as these have helped with discovery issues in the past.
With that said though, I don’t think I’ve seen the behavior you describe of Roon searching for a specific IP, generally the only IPs that appear on that page are the ones of the Cores on the network, what does the 192.168.178.2 IP map to, is that another device running Roon?
