The upstream levels of 54dB, is the maximun levels when the upstream is QAM16, this will need lowering, now does the OP have internal splitters in the house, like a VM STB also installed as well? As this will again affect upstream and downstream levels.

Once the levels issue is sorted, the person your helping will need to find out what version modem they have, Ambit 250-256 will be fine, better with latest versions of 255/256 though, if none of these get it replaced when Tech comes to fix levels issues. Also take out the router do ping test then reintroduce the router, again perform ping test. At each stage note if your experiencing packet loss or not.
