Multiple modem dropouts throughout the day (T3 Timeout)
Issue: Throughout the day, my modem loses internet connectivity and essentially goes through a re-connection process as if I did a manual reset. This occurs about 10+ times a day especially between 9-3pm and even more so during hotter temperatures. (Southern California, Single Family Home).
Note: I have tried to fix the issue by replacing the Modem, but the same issues persist.
- Arris SURFBoard SB6183 (previous)
- Motorola MB8600 (replaced the SB6183 when I assumed connectivity issues were tied to the modem -- it wasn't the problem)

After observing the Event Logs the last few hours, I keep seeing T3/T4 Time-Outs whenever internet access drops-off. I included a sample below:
Does anyone have any additional thoughts in troubleshooting? Or potential root issues?
My current plan is to purchase brand new coax cables to connect the modem directly to the cable line to the street / ground block and see if the problem lies with existing routed cable and any splitters in its path.
Thank you for reading and any responses.
