Firewall Blocked messages and reliability

This is our modem:
Hardware Revision:2.3
Serial Number:333136486
Processor Speed:1503 MHz
DRAM Total Memory:1024 MB
DRAM Used Memory:465 MB
DRAM Available Memory:559 MB
Flash Total Memory:512 MB
Flash Used Memory:2 MB
Flash Available Memory:22 MB
we get these messages in the firewall logs:
FW.IPv6 INPUT drop , 43 Attempts, 2019/11/07 18:34:12Firewall Blocked 
FW.IPv6 FORWARD drop , 10542 Attempts, 2019/11/07 18:34:12Firewall Blocked 
Any reason to worry?  
Also this model was swapped in during our recent upgrade to business 1Gig (about a month ago).  It used to be very flaky (requiring constant resets/reboots) UNTIL I changed the password last week... I know that sounds nuts, but is there a correlation?  Our comcast tech told us these new modems are very buggy.  Or was there an automatic system update that automagically fixed our dropped connection issues?
Best regards
