You need to contact the ISP and have them review this. They need to check the signal up to the modem and ensure it's working well. If testing another modem results in same better operation, it's possible the CM maybe bad if the ISP checks things out.

you DS power is quite high but that itself may not be the issue.
Are you losing SC-QAM Locks as well?
