You dont need a d3 cfg. You need a d3 cm. D3 is backwards compatible with d1.1/2 so you will get a d1.1/2 cfg file from the ISP. If you can still serve or force cfgs then you can use a d3 cfg file on a d2 cm but it wont go any faster than 35 down or so depending on your network/signal quality as the 5101 cannot use multiple downstreams due to it only having 1 tuner...
