I Arris gateway and 3 portals. current setup is gateway and 1 portal in living room and 2 portals in the 2 bedrooms. The gateway is noisy and lots of heat and I need to keep door of my stereo system tower open all the time to release the heat. My question is can I just move gateway unit to the spare room or garage but keep 3 portal in the same place. (so there is no portal connect directly to gateway)?
