Several users have posted suggestions to move away from Verizon's DNS servers, suggesting Google's DNS and OpenDNS. You could try those.
Myself, I peridodically run DNSBench, freeware from Steve Gibson, to see what DNS servers look good here. I'm currently using Verizon's 151.202.0.84 and 151.202.0.85.
I noticed that your router's address is 192.168.3.1. I assume you have some reason for not using the default 192.168.1.1, but are all the other devices you're using assigned the 192.168.3.x subset?
Here's what I see if I ping brokenlinkcheck.com:
