You can use any cable or DSL modem with that router. The SBG1000 is a cable modem and wireless router in one, you may want to make sure the wireless signal on the SBG1000 is turned off before you install the D-Link. The signals might interfere with one another. You may need to keep the SBG1000 since your cable provider might use its serial number or MAC address to authenticate you as a user on their network, and the D-Link doesn't include a modem built-in. Note that the DGL-4300 does not have WPA2, it does have WPA-Personal and WPA-Enterprise along with 128-bit WEP and MAC filtering. That's always been enough for me, my neighbors are technological Luddites so I don't really have to worry too much about my encryption protocol. The D-Link DGL-4500 IEEE 802.3/3u, IEEE 802.11a/b/g, IEEE802.11n Draft Xtreme N Gaming Router
has it, but is more expensive. I'm not sure if you want to spend the money on the DGL-4500, I selected the D-Link DIR-655 IEEE 802.11n (draft) IEEE 802.11g IEEE 802.11b IEEE 802.3 IEEE 802.3u Xtreme N Gigabit Router
as a good middle option that has WPA2. Note that NewEgg is running a special on the DGL-4500 until Dec. 19, you can get free shipping and an extra $20 off by using the "DlinkXmas4500" coupon code.
