Yeah I saw your IP address there, it is generally not a good idea to post it anywhere on the web, so the Mods here typically remove any IP addresses.
The reason I suggested checing the coax connections is that FiOS uses different frequencies to transmit internet data (and TV signals if you have that service), and coax is notorious for loose or corroded connections, or damaged cable, causing poor signal levels and quality at only certain frequencies, while passing signals at other frequencies just fine.
You indicated that this problem showed up since last Thursday; I wonder if maybe some update to your system, from Microsoft or maybe from your network adapter manufacturer, is causing this. Can you maybe try using System Restore to set your system back to a time prior to when the problem showed up, like Wednesday, and see if the problem goes away? This will only affect system files, not your data files, etc.
One other thing you might try is to turn off your router overnight to force getting a new IP address. I don't know why this would help, but you never know....
I wish I had more help to offer, but as you can see I can go to the same Verizon server and get perfectly good results, so I do think it is somewhere in your house. I hope you can find a solution quickly, and when you do I hope you will come back and tell us what the problem and solution were. Once again, good luck!
