Replace the T3200M with a new router but keep wired optikTv working

Hello!

Sorry for the delay! In the meantime, a lot of things have happened and I have done several that leave me, how can I say ... perplexed.

Regarding your suggestion of everything with the TV via the wall cable, it is also an idea that I had!

Unfortunately, when I wired the house in RJ45, I determined that the junction point would be the basement staircase and so I had all the cables from the house arrive there.

So, I can not move the interconnection devices anywhere. Sadly.

To make a long story short, my initial fantasy of completely replacing the Telus router never came true despite strangely encouraging tests at times.

I can not remember everything I did, but I managed to spend an evening without the Telus modem and with the TV working at the same time, but the next morning the TV no longer worked.

I tried:

1. My new router alone on the ON: The TV works in waves of 10 seconds, I change channels and I win a new 10 seconds and so on.

2. My new router connected to the ON and the Telus router connected to my router: Same result as 1.

3. Telus router on the ON with my new router on the Telus router and the TV on my new router: Works longer than 10 seconds, almost 1 minute on average, but the first time it succeeded for the evening and it was only the next morning that I noticed that the 10 to 30 second problem returned.

Finally, I am connected as described in my very first publication.
ON -- TELUS -- New ROUTER
                      -- TV

For the android media box, I reactivated the Wifi on it and since the new router is more powerful than the Telus one, being on Wifi is a more viable option than before which means that I can drop its wired connection which solves my need to have both a connection to the Telus router and my new router in the living room. Also, since the Wifi is on the new router which itself is connected to my entire network, I can access my media server, travel photos, music, etc.

For the rest, according to my research, the GL iNET Flint2 is supposed to be multicast compatible, but the configuration seems so complex and so different from all the tutorials I found that I don't think I'll have time to get started on it before the Christmas holidays. (I can't find the link tonight because I'm looking for it, but I found a forum post from a guy who managed to get his third party router to work with the TV using a setup he found online on a UK site if I remember correctly)

Thanks again for your help and if you can think of anything else that could improve my setup, you're welcome to do so.
