My ISP/IPTV provider recently changed their equipment and the new boxes are running Android Oreo (model is HPH07) with a custom IPTV app on top of it. I managed to get to the underlaying system and installed a couple of apps no problem so I can use the box as a general purpose media player/streaming box.

My problem is that you have to connect their boxes to their modem/router (can't work through a switch or even on wifi) and it connects only for IPTV service with no internet on the cable or vice versa if I manage to get internet on the connection first there is no tv signal. My guess is they tunnel the connection to an IPTV only server on their network (when I check the IP of the net connection it is not on my internal network).

Therefore I want to be able to set certain apps use the Wi-Fi connection for general purpose internet and keep the ethernet just for the IPTV. I know I can do that on a phone with Wi-Fi and Data, but can't find a way to do it with ethernet and Wi-Fi. Anyone know of a way to do this? Even an app would probably work as well.
