Repeated Connection Drops

Started having connection dropping over and over. Modem logs showing errors. Unsure if this is related but there was an outage in my area yesterday. I think my power levels and SNR are in appropriate ranges but I am getting these errors in the logs of my SB8200. A technition was here recently and replaced a splitter and the conector which showed some corosion. What additional troublshooting can be perfomend or what are the next steps I should take?
