+1 for getting rid of the Modem and replacing it if you can't dumb it down into "bridge" mode so it just acts as a modem rather than a gateway. Up here in the Great White North the Tier-1 ISP that my ISP rides on top of forces them to use a crappy modem but luckily this can be forced into bridge mode which gets rid of the double NAT and also another layer of potential trouble.
I googled the model number and "bridged mode" and found a whack of guides for doing this. Whether you can do it easily depends on your ISP.
You will also, of course, need a router behind the modem once it is in bridge mode. If you are also using IPTV then things can get a little tricky due to the VLAN tagging used by ISPs but again there are lots of guides out there.
