Router lan ports not working! Help!

[The_Legendary_Windows]

So I my ASUS RT-N16 router just came in the mail today and I installed DD-WRT on the router. Everything was working fine until all the computer (4) connected on lan just suddenly cut out and it doesn't work anymore. It just says there's a limited connection. WiFi on the router works fine and I can get on the DD-WRT control panel, but on the top right hand corner it says "WAN IP 0.0.0.0" I've already tried factory restoring the router, reset modem, and resetting the router. Before when I got it working, the IP was 96.35.47.196, then went to 0.0.0.0, and finally went to 24.217.228.193. And I only have internet access on wireless devices, not LAN. Please help!
