Nice one, it will almost certainly be a
SuperHub, a combined cable modem / wifi router in one box. Don't worry too much about some of the old comments online about this router, most of the complaints come from the time before the latest firmware (R30) when it couldn't be put into "modem only" mode and used with a 3rd party router and it's wifi performance was average, both of which were fixed in R30.
The router side still has a few annoying limitations, like being unable to set your own DNS servers (coming in a future firmware apparently) but if that's a problem for you you can just stick it in modem only mode and connect your own router to it instead. - I make do with using it in modem and router mode though as it's wifi performance is much much better than my old D-Link.
