You must retain the router that Verizon gave you as the CE (Customer
Edge) device, otherwise you can't stream on demand video and the like.
However, you can disable its wireless port and install a WRT54G (about
half the cost of an RPi on eBay)

The docs shipped with the kit only reference Mach. Need to pick useful info

The regular thumping noise, about twice a second, seems

perhaps there is a video driver problem.
