If you want real gigabit fibre optic class speeds you ll need to invest in a docsis 3 1 cable modem jesse hollington tech writer.

Cable modem good snr.

Ideally at 0dbmv and snr 36 40 db range. Snr signal to noise ratio levels. This means information coming down from the internet to your modem. The current download speed established between the dslam and your modem snr signal to noise ratio 18 8db signal to noise ratio on the line.

The three signal levels that need to be within the acceptable level are downstream power snr signal to noise ratio and upstream power. Your cable modem is connected to a coaxial cable that leaves your house. The motorola mb7420 is the best cable modem for most homes capable of supporting speeds available to a majority of home internet plans.

A value below 55db is good dslam results your location to telkom exchange general status. Signal to noise ratio. The modem status will show the downstream snr signal to noise ratio which usually should be above 30 mid to upper 30 s is good over 30 usually means you ve got too much power anyhow and under the 25 30 range you re gonna start losing packets. Check the signal to noise ratio snr or s n on the cable modem.

The higher the snr the better the signal. And upstream is normally 36 51 dbmv and with 3 channels bonded. Hope the above info is helpful.
