New Modem/Router upgrade is dropping connection regularly

I upgraded the modem with the internet speed upgrade and have nothing but connection issues. The event logs have Critical and Warning messages related to mismatch of connection. Please advise !

What do the modem's signal status values look like ? Try getting them here; http://192.168.100.1 

Please copy all of the text in its entirety of the *Downstream Power Levels*, the *SNR's* (Signal to Noise Ratios), and the *Upstream Power Level* numbers and paste them into your next post.

Also. Are there any more error log entries being shown ? If so, please post them as well (copy and paste them, don't post a screenshot) but redact any CM MAC and the CMTS MAC addresses for privacy.
