I woke up this morning to no internet access. After unplugging and plugging the modem back in, I had to wait a couple of minutes for the modem's lights to stop flashing. When they did the second light is lit blue. Never seen that before (usually green). I check 192.168.0.1 and I now have 4 channels listed in "downstream".
My download/upload speeds are really fast now. Upload only went as high as 2.79 before.
