So the problem is that me and my brother want to get different internet lines for the house (one for him and one for me) because we keep arguing with each other about lag and other stuff. So basically, our house has 2 phone jacks, one in the kitchen and one in his room. He's planning on getting comcast for himself and I want to stick with the current AT&T internet plan that we have. Would that be possible? Having a comcast internet line in his room and the other AT&T internet line connected to the kitchen for me to use?
