I you search for "Comcast Approved Cable Modems" a result pops up from Amazon that shows the approved modems that are on sale at the site. It is a non-official list. The official list is at the URL below. It could be that some of those modems cannot be used in some Comcast areas, but could be used in other areas.

It looks like some of them are combo modem/routers, but there are a bunch on the list that have no routers in them.

Having two routers in line between your computer and the net is a configuration that most users will not be able to properly configure. However, a few users will be able to get that setup working. If a user can avoid it then that is the much easier way to go.

To make a two router config work you could do one of the following:
- declare static route(s) - the network works best with this solution
- use RIP to "sync" the two routers up
