My internet speed over the past few days has greatly decreased in download rate 2.5 Mbps ( Im currently on the 75 plan). At the same time my upload rate has seemed to get a higher range, approx 8 Mbps. I've tried connecting to the modem with a computer for a speed test and no change in speed was noted, so I know it's not just a wireless issue. My modem is the hitron cgnm-2250. Any help would be greatly appreciated...ohh, and I've already tried the resetting the modem and factory resetting .
