I just gave a DOCSIS 3.0 modem to a friend who was paying $7 per month on a DOCSIS 2 modem that couldn't provide the subscribed speed. Comcast had already charged her for a couple of truck rolls to troubleshoot the speeds, so it boggles my mind why the rented modem had not been replaced. Even more interesting is that Comcast does have infrastructure in place to notify customers of these issues, though I have only seen them use it to convert customers who bought equipment back to renting. When I bumped my modem into the D3.1 threshold last year, the company made a number of calls to let me know that I could improve my experience by going back on a rental plan.
