I have 2 isps connected to my house. One is cable and the other is DSL. I am wondering whether I can use one powerline adapter set for cable and another powerline adapter set for DSL. In other words, can the powerline carry data information from two different isps at the same time or not?
If you use 2 different sets on 2 different encryption they will be completely separate....but they will still share the total capacity of the wiring in the house. Hard to say how much they will interfere best case they would each get half but I bet it will much less.
