I have had a bit of a go. As already mentioned, the setup consists of 2 steps. 1. internet setup, 2. TV setup (set up multicast). In this community you will find everything you need to set up your router correctly for all common routers. Wingo is not on the main page, but you can find it in the attached articles: Setup for (Swisscom, Sunrise etc.):
https://community.ui.com/questions...
@tonoriesco has then adapted the config for Wingo:
Everything is exactly like the swisscom config except the :
set client-option "send vendor-class-identifier "100008,0001";"
I you don't change that, you always fall in the Swisscom IP and there is no way to have an IP. For Wingo, the client-option must be empty.
