as I quickly learned and would give the same advice to prospective Extreme owners.... let Emile set it up. This is his baby and brain child. It’s not his first rodeo. Truly he will have you up and running even remotely. Let him do the setup. There are so many things that can be changed. He asked me with each one and he did the input. I’m happy with the outcome.
I will give him full bandwidth - I will only power the system and connect the cables! He has other customers with Vivaldi systems, it should be a quick set-up. How are you controlling the system?
