I'm currently in an apartment where the DVR/Receiver (a 8742HDC) is in the living room and the cable modem is in one of the bedrooms where my computer is. Cable modems are primarily used to deliver broadband Internet access in the form of cable Internet, taking advantage of the high bandwidth of a HFC and RFoG network. Second point is, when I had a Comcast cable modem I was constantly losing Internet service. These levels apply to all SURFboard cable modems and cable modem/gateways. 5.24” x 5.24” x 1.65” Weight in Lbs (with packaging) 1.52lbs This frequency range is typically from 5 MHz to 42 MHz. A cable modem is a type of network bridge and modem that provides bi-directional data communication via radio frequency channels on a hybrid fibre-coaxial (HFC) and RFoG infrastructure. If your cable modem reports more than 52 upstream power, you need to look at your cables and splitters.
