Has a Comcast tech out the other day and he watched the levels for 15min said everything was fine. After he left problems with the modem dropping out and SOMETIMES coming backup by it self began again. Took my 1 month old modem back to BestBuy and got a brand new one. Same problem within 10 minutes. This is my specs and log information. Someone please give me an idea of what is going on and if anyone needs more information just let me know.
