With default settings the router will assign you an IP just like it does on WiFi - just set your ethernet setting to automagic and you should be able to see the router.
As per usual, check the modem and the router firmwares are up to date. If the router is pretty old, then it is possible that the firmware is old enough to not know what the new card is. When the HSDPA cards first came out, the routers needed a firmware upgrade to see them.
