I have been long experiencing intermittent drops on our internet and phone service ranging anywhere from 1 or 2 minutes to 20 minutes or more. This happens anywhere for half a dozen to 15 or more times a day. I recently bought my own Arris TM822G hoping that would solve the problem (while saving money). It has not helped. My signal levels always check in the proper range for both down and up and SNR is good at about 37 to 38 dB on all channels. Upstream power is 43.5, 44 and 45 dBmV. During a phone call with our son today, the phone line went dead twice. We could hear him but he could not hear us. Both times, an Internet Connectivity Monitor (ICM) that I often run logged internet drops at exactly the same time. Likewise, the Event Log of my modem has entries indicating some kind of error at the same 2 times. I have saved those logs for review, noting the phone call drops.
I assume this is some kind of neighborhood problem or a problem at the pole. I have Mediacom internet and phone service at my business and rarely have problems - always connected with more widespread problems.
BTW, while writing this, my ICM logged two drops of at least a minute long.
