Signal levels are very important for cable internet. The below levels are the acceptable ranges for a cable internet connection:
Downstream Power Levels: between -11dBmV and +11dBmV
Downstream SNRs: greater than 32dB
Upstream Power Levels: between 35dBmV and 52dBmV
Your connection's signal levels can be viewed by you at any time by accessing the management interface on your modem (http://192.168.100.1).
If you notice that your signal levels are out of range, please contact us immediately at firstname.lastname@example.org .
EXAMPLE: a difference in the SNR as small as 2db (30db vs. 32db) can cause over 90% packet loss. This will result in slow speeds in some cases or complete connection loss in
