Computer Receiving WAN IP instead of LAN IP

I caot for the life of me figure out what is going on. I recently purchased a Netgear CM400 cable modem and a Netgear N300 router.

I was able to successfully configure my CM400 with Time Waer Cable, my inteet provider and successfully coect while having my laptop plugged directly into the cable mode.

I then hooked up my N300 router and after a couple hours of messing with it was able to get inteet across my LAN. However, the catch is my IP Address on my local machines is being reported as my WAN ip provided from TWC, not my local IP provided from the router, which prevents me from accessing the router admin page.

I've tried even statically setting my local IP to that of what would be assigned by DHCP on the router to no avail, the coection dies and nothing works.

I have no idea how to fix this - would appreciate any help!
