Cable Modem Good Snr

A value below 6db can cause problems attenuation 19 5db the amount of resistance on the line.

Cable modem good snr.

Although there are docsis 3 0 cable modems that technically support speeds of 1gbps or higher chances are that your cable internet provider will cap out at 600mbps over docsis 3 0. For cgn3 you should have 20 channels bonded. Ideally at 0dbmv and snr 36 40 db range. The motorola mb7420 is the best cable modem for most homes capable of supporting speeds available to a majority of home internet plans.

Snr signal to noise ratio levels. This means information coming down from the internet to your modem. Hope the above info is helpful. Your modem is receiving good signal.

A value below 55db is good dslam results your location to telkom exchange general status. The higher the snr the better the signal. And upstream is normally 36 51 dbmv and with 3 channels bonded.

The opposite of upstream. Think of wherever that goes as upstream. Generally speaking the signal should be for downstream between 10 dbmv to 10 dbmv.
