Network connection issues are always complex and usually not streamer dependent (as in it wouldn't matter whether you're running Optical Rendu or 2Yu+2Go).I currently use a rather high end router in the ASUS RT-AX88U. I also have a Devolo powerline ethernet adapter that feeds goes to the Optical Module Deluxe, which in turn feeds the Optical Rendu. I got the Devolo adapter replaced to eliminate it as the source of the problem- which did not help.
If you're running on Wi-Fi (the whole system or part of it which would be necessary for your iPad to control Roon), buying a bigger router like ASUS RT-AX88U doesn't always help because the new problem probably started because your neighbor's new Wi-Fi router is interfering with yours so now you have a bigger router to overpower your neighbor's router but your neighbor can always get an even bigger router. Moreover, interference is usually intermittent and unpredictable.
Powerline products can be very helpful if you can't physically wire your router to the Optical Rendu with a physical Ethernet cable. However, even these Powerline products work less well with distance which can affect connection speeds but usually for streaming audio, it should still be more than fast enough. Although for audiophiles who love using power conditioners, these power filters can potentially filter the signals from the Powerline products so one has to be careful which power socket they use for the Powerline products. The bigger issue is that now some Powerline products have Wi-Fi router built-in. So your Devolo Wi-Fi can potentially interfere with your ASUS Wi-Fi and together with interference from your neighbor's Wi-Fi it becomes a bit of a gong show.
Note none of the above discussions have anything to do with Optical Rendu vs 2Yu+2Go.
Ultimately, it would be best for @NYanakiev to describe the current network setup in detail and the connection issues that are occurring. But I'm not sure if this is the best thread to discuss the issue. Not sure if @NYanakiev wants to PM me to talk about this more or whether @NYanakiev wants to just post more information about the issues and then let people PM him back with some suggested solutions.
