It all depends on what sec features are being used by your ISP. Obviously, not many, if you can just swap a mac. Or, did only a full clone of the cm work? Does your isp push a firmware update on the modem? Unfortunately, we can't diagnose your node from here. Why not post a telnet boot log of a successful handshake (edit out all ip's first!). Do it with Hax Diag so you can see everything.
