Is the T25 modem capable of supporting 240 Mbps upload speed. It is rated to support 8 upstream channels - but my current device shows only 4 upstream channels are enabled. With 4 upstream channels I can only theoretically get 4x30 ~120 Mbps.
Does anyone know what upstream frequencies comcast use? There isn’t enough bandwidth in the RF split (5-42 MHz) to support 8 channels so the diplexor config of 5-85 MHz need to be enabled to get full 8 channels. Does comcast need 4 upstream channels with 2x2 MIMO for its 200 Mbps upload speed or does it utilize 4 channels?
