Comcast users: disable Gateway Smart Packet Detection

I just ran across this article.

Apparently, the cable modem that Comcast ships to business internet customers has a "Smart Packet Detection" feature that has a nasty habit of making connections go flaky from time to time. According to one report I read, it was actually causing the router to drop every other packet, which will obviously make your user experience less than ideal.

I'm not sure what this feature is supposed to do, and Googling reveals nothing but recommendations that you turn it off. But if turning it off fixes your problems, then I'd recommend doing it. Comcast's support staff don't always know about this, so they might not tell you to try this unless you're persistent enough to get your call escalated to high-level techs.
