Signal-to-noise ratio (SNR) is a gauge of signal strength to and from your cable modem in relation to the background noise. The ideal SNR range is 30 to 50 decibels (dB). High noise or low power levels reduce the SNR and can negatively affect your Internet connectivity, resulting in data loss or slow speeds. Such issues can be caused by problems with wiring or connections but are rectified easily. Tips Warnings Writer Bio
