I spent the entire day troubleshooting this issue, just as I have been doing for about the past week. It occurred to me I failed to mention what was probably a vital part of the way I have my internet connected, which is I had my ONT connected to my router via powerline adapters (it wasn't a direct connection), which I suspected for a while was at least part of the issue, but didn't initially want to admit or change it. My ONT is in a closet and my router is in the living room. So, I finally gave in and removed the powerline adapters and connected my ONT directly to my router via a 25 ft CAT6 cable that I had lying around. After all that, I was still having the issue, so I did some more investigating, and come to find out, I'm experiencing what is a well known issue with Verizon FIOS, especially for those who opt to use their own router, which I did. The issue is that the lease between the ONT and the router is not renewed properly. A common solution is to powercycle the ONT, then powercycle the router, however, since I opted in to receiving the battery backup, I have the additional step of removing/unplugging the battery backup before powercycling the ONT. This is too much to do every 2 hours for the foreseeable future, so needless to say, I will be calling Verizon tomorrow.
