DIR 615 DD-WRT headache with connecting to internet

Dear Experts,

I got DIR-615 router and installed DD-WRT and having issues connecting to internet.

DIR-615 E4 with DD-WRT build 16454

ISP details in the router

STATIC IP - 10.10.0.109
SUBNET    - 255.255.255.0
GW        - 10.10.0.1
DNS       - 10.10.0.1

I have dhcp enabled on the router, all settings are default to what DD-WRT provides.

Routing table as follows

Destination     Subnet Mask        Gateway    Interface
10.10.0.1        255.255.255.255    0.0.0.0    WAN
10.10.0.0        255.255.255.0        0.0.0.0    WAN
192.168.1.0    255.255.255.0        0.0.0.0    LAN & WLAN
169.254.0.0    255.255.0.0            0.0.0.0    LAN & WLAN
0.0.0.0            0.0.0.0                   10.10.0.1    WAN

My problem is that the wired laptop always tells that the internet is not accessible.  Iam getting the right IP from the DHCP router.  pls help me with configuring the router correctly so that i can connect to the internet
