how many downstream channels does comcast use

My TV can go to 135, as can my RF Modulator (used to send the DVR's signal to a bedroom TV), but it didn't work well. While it isn’t outstanding in any way (modems rarely are) it features normal transfer rates along with good router capabilities, which is exactly what you’d want. Since about 15% of Comcast cable systems are 550 MHz systems, this has held back providing more HD channels. However, apart from Comcast, the supported ISPs send the data through DOCSIS 3.0, which is why the transfer rates of this modem are only better theoretically. Most original modems only support 4 channels.Upstream is about 30Mbit raw (27Mbit after overhead) due to different modulation. Then again, ARRIS has pretty bad customer service, so you might have tough luck taking advantage of that better warranty. The modem provides 32 downstream channels along with 8 upstream channels for DOCSIS 3.0 and 2 OFDM downstream channels along with 2 OFDM upstream channels for DOCSIS 3.1, with maximum download speeds of 10 Gbps and upload speed of 2 Gbps. If you are intending to use a separate device for routing, then make sure that the WiFi transfer rates or the Ethernet port transfer rates are higher than the transfer rates supported by the modem, else your transfer rates will be limited to the router’s limit. The higher frequncy should allow more bandwidth also. Using the current 256QAM modulation, each channel is about 42.8Mbit (I think closer to 38Mbit when overhead is accounted for). The Netgear has a superior GUI. Very low frequencies, below 10MHz, tend to be very noisy and are usually used by cable boxes as their return channel.From the summary on Wikipedia, there is no limit to the number of upstream or downstream channels in the specs.
