I recently had Cox install Panoramic modem/wifi combo. Extremely disappointed in the range and performance for my Roku players. Some simply do not play at all. Modem/router is in the center of the house and it's not a huge house(single story 2200 living). I'm thinking about purchasing my own modem and running three separate routers in the attic above the areas where my TV's are located. Does anyone have any input if this would work or not????
