Serviio

Hello. Yesterday I changed my internet company, and they gave me a ZTE ZXHN F6640 router. Since I have it on I can no longer access the service on my 2016 samsung, which with my previous router from the other company I did not have to configure anything and only the app came out directly on my TV (DLNA).
What do I have to configure in my new router to be able to continue using the service (DLNA) in my old samsung tv? All the best!!!.

I can't find any manual for that model online. Are all your devices connected via WiFi, or is there any mixture of Ethernet and WiFi? There's usually a security setting for the wireless radios that block connected devices from seeing each other. Since the only thing that has changed is your router, it has to be a setting within it.

Problem solved, call the technical service of my company and they solved the problem, thanks.
