This has been going on for a few months, but seems to be directly related to the amount of data downloaded. The below log was during the download of Windows 10 (2.6 GB and downloaded successfully). As you can see, the modem lost connection 9 times (counting the T3 timeouts). On days with less/little modem activity, there will be only 2-3 disconnects/reconnects. Signal levels have always been very good, and still are, so I'm not sure just what the problem is. Modem is a 4 year old Motorola SB5101U connected on a Mediacom 15/1 std pkg. Speed tests always report 24-27Mb/s DL & 2-2.3 Mb/s Upload. Router is a 4 month old TP-Link WR841N-V9.0 with current firmware. Modem has direct connection to 1st 2 way splitter, and this is in a single family home.
