MB8600 T3 time out and WAN IP drop

Hello,

Within the past few months I have been getting T3 timeout errors in my event log and our. We had a tech out here late last week and the issue returns on occasion. Randomly, seeimingly in the middle of the night, the modem WAN loses its IP and causes my router to lose WAN access until I restart the modem.

Troubleshooting already done: factory reset modem (no change), replaced modem (just replaced yesterday and T3 generated on boot)

Is the downstream power slightly too high and upstream too low?, i.e. channels 3-11 on the screenshot.
