If no obvious problems exist or repairs have not improved the SNR values, try moving the cable modem to the most immediate entry point in the facility. Attach it to the main feed, if possible. If the SNR values are good, then the problem is cabling in the facility. If the SNR values are still unacceptable, the problem is in the cable modem, outside cabling or equipment of the cable provider. You can try changing the cable modem, if you feel comfortable with that task. Otherwise, it is time to get the ISP/cable provider involved. You can report your findings of the SNR values.
