Cable Modem Good Power Level

To view the upstream and downstream power levels.

Cable modem good power level.

The power level on all downstream appears to be good 1 5 3 3. 2010 04 10 08 58 44 mprogers technically low transmit levels upstream power can cause. It has 8 downstream and 4 upstream channels. Downstream and upstream power levels are important when determining if the cable line that is connected to your cable modem or modem router is receiving sufficient power.

Upstream power shows the level of the signal from the cable modem to the provider. Launch a web browser from a computer or mobile device that is. The three signal levels that need to be within the acceptable level are downstream power snr signal to noise ratio and upstream power. Good upstream power levels are within 38 48 dbmv.

Downstream power level rx this level is the downstream signal strength and can be plus or minus and shows the amount of signal received by the modem from the cable companies transmitter. Good downstream power levels are within 7 to 7 dbmv. 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. The cable modem s power levels should be within these ranges.
