I wanted to report some issues I hvae been having intermittently for a year or so with severe packet loss.
Initially, I started noticing that certain sites using HTTPS would have to be refreshed several times to load properly and were slow in general. Regular HTTP sites and even speedtest.net usually seemed fine.
I ran Wireshark directly from the ONT (no router) and it was reporting 5% packet loss, or rather a lot of TCP retransmits (indicative of packet loss). This was occurring 24x7. Eventually the techs began daily visits neighbor's house for 2 weeks and the problem *mostly* went away.
Now the problem has reappeared, but worse. During the day there is 1-2% packet loss, within the "acceptable" range, and not causing much trouble. However, every evening from 5:00p.m. until after midnight I am getting 5-15% packet loss, tons of out-of-order packets and failed tcp checksums. It makes the internet basically unusable. Any interactive site using HTTPS does not work, (think shopping or banking), even regular HTTP sites are having problems. Ironically, there is no way to file a support issue while this is happening.
I know this is a problem between the ONT and the network, the question is how do I get this fixed without spending 8 hours on the phone with a tier 1 support person who will make me install a bunch of random hardware and make me unplug everything and reset my router, etc.
