Im in Northern VA, and all day today I've had issues with my signal-to-noise ratio rapidly fluctuating. I'm on the Preferred plan and still have a Scientific Atlanta DOCSIS 2.0 modem (yeah, I know). My connection has been pretty stable for the past 6 years at this address. Usually, the SNR stays above 36 dB and rarely moves around; today it has been anywhere from 35 to 28 dB. This has equated to painfully slow page loads and d/l speeds maxing out at about 1.5 Mbps (when directly connected to the modem and on wi-fi). I tried changing out the coax cable between the wall and modem to no avail. There are also no splitters inside the house. Anybody else in the area experiencing such issues?
Well depending on how old the modem is, it may be time to replace the modem. As a failing modem can start to have problems with signal levels, and such.
