Well the 3 mbps is a joke. It's maxed out at 2.6 and normally operates between 900 kbps and 1.8 mbps. Not to mention the modem in itself is a joke, which granted won't be solved by doubling up but I can deal with one annoyance for 40 less a month. At the end of the year I'll kill it anyway and get Comcast's 6 mbps down 756 up.
