The forward modulation used is determined by the environment variables in your service area. Just as AM and FM are two methods of transmitting radio, we also have a few methods of transmitting data to your cable modem. Remember, closer to 0 is better.Įnsuring your cable modem is on the earliest split (coming from outside your home) or no split at all helps ensure your modem works at it"s best. ![]() In other words, if you have a 4-way splitter with two unused ports replacing that splitter with a two-way split would be the difference between having a -10dBmv and a -13dBmv forward signal. In general each "port" on a splitter equals about 1.5 db of signal loss. If you have unnecessary splitters or splitters having more ports than you need, consider removing or replacing that splitter with one containing only enough ports as you need. Here's some tips you may try in an attemtp to get this number closer to 0 however, these steps only work if you are at a value that is less than 0.Ĭheck the coax cables in your house ensure they're all nice and tight. ![]() If you are just outside this range, don"t worry as long as your modem"s working all is well. While a value of 0 is ideal, the signal should be somewhere between +/- 15 dBmv. The forward power level reported by your modem represents how strong the signal is from RCN"s transmission facility when it reaches your modem. Rest assured that RCN has selected a frequency that optimizes performance in your service area. These channels are not viewable on your TV since it"s designated for cable modem service.ĭesignated frequencies may change by location and potentially even neighborhood. Note: in terms of cable modem service, "forward" is the downstream or download side of your cable modem service and "return" is the upstream or upload side.įorward frequency is basically the "downstream channel" the modem tunes to for receive service. This may be helpful to identify malware generated traffic or to simply satisfy curiosity in determining how much bandwidth a particular application uses. ![]() In addition to testing your upload / download speeds, you now have the ability to monitor your cable modem throughput. Utilizing this approach allows for greater accuracy and simultaniously accounts for traffic passing from multiple hosts behind a modem (IE: home networks). This is done by passively measuring traffic throughput directly at the provider"s side of the cable modem rather than the at the client side. RCN"s speed test is custom built to accurately measure data throughput between the cable modem and RCN"s network. According to negativeduck - these are best to use for a multitude of reasons
