I dumped DOCSIS the moment fiber became available. With cable, I'd go through periods of 1% to 3% packet loss. It also affected the neighbors, so it wasn't my "old modem" as the tech once tried to claim. When it was at its worst, I saw my upstream bandwidth drop below 100kbits/sec due to all the TCP retransmissions.

Eventually they admitted it was an "outside plant" issue and beyond the responsibility of the home techs. It took months to finally get it fixed. Who knew if it was actually fixed, or it was just a fluke, since the problems would come and go.

Even when it worked, upstream was capped at 30 megabits/sec, which was pretty painful for large uploads.

Fiber has none of these problems.
