I don't think that ownership of your modem gives you or anyone else more flexibility for testing or experimenting on the ISP's network. The modem might be yours but the network belongs to them. I would get a few tools (mostly USBtagNT) and buy another modem (SB5101) to test with. Make a couple of good backups of the modem you buy and then flash some old bins on it with hax and hook it up to the coax and see what happens.
