SYNC Timing Synchronization failure - Loss of Sync and other error logs from this past month

We've been having issues all month with our internet connection being very sporadic.  I tried to look into the issues by logging into the modem and looking at what errors it was generating but I'm just not understanding how these errors all interact and what the issue is based on what they say.  Any help would be most appreciated.  Connection speeds have been all over the place from 1mbps to 100mpbs with random disconnects.  Thanks in advance.  Here's the full log:

Please also post the *Downstream Power Level*, the *Upstream Power Level*, and the *SNR* (Signal to Noise Ratio) numbers.

What is the exact make and model number of the modem ?
