WebSignal to Noise ratio (SNR) is a ratio of powers, hence it's always greater than or equal to zero. On the other hand, very commonly, SNR is expressed in decibel (dB) notation: SNR dB = 10 log 10 ( σ x 2 σ n 2) where σ x 2 and σ n 2 … WebRefresh the page at least twice to identify variations in SNR, Downstream Power, and Upstream Power. NOTE: If the either of the signal levels are outside of the acceptable range, power cycle or factory reset the modem.; Contact the cable provider to adjust the signal level to the acceptable level range.
