Motorola MB8600 Constant Reboot (noise on Xfinity line?)
I have a Motorola MB8600. I'm subscribed to Xfinity for 500Mbps download speeds and 10Mbps upload. Each day, for the past three weeks, my internet download speeds have dropped to <1Mbps. Upload speeds are stable. The only way to fix download speed is to reboot the modem. Post-reboot, download speeds return for some undertermined amount of time (1hr - 1 day) before I have to reboot again and repeat the process. Xfinity has been of no help to me in solving this issue and basically pushed me off to contact Motorola directly, which I've done. Motorola says the modem is operating properly, so now I'm at a loss about the best way to proceed. I have 32 downstream channels (QAM256) with a Pwr (dBmV) range of -13.4 to -20.3 and SNR (db) range of 32.4 to 38. Question is, is this range of noise on the Xfinity line acceptable, and if not, how do I get Comcast to help me!
