jnr1010v2 is not connecting to the internet but working fine when i connect cable directly

Hello,

I have a 1 year old netgear wifi router, model number JNR1010v2. It was working fine until recently. It does not connect to the internet since a week .I suspect that it is because of the firmware upate to VersionV1.1.0.32_1.0.1. Since then i am facing the difficulties in connecting. I have showed the problem to my Service provider and he said the MAC id is the problem and he removed the MAC id for my connection. But after a week of the fix i am facing the same problem.

However, I am able to connect to the inetenet if i connect the ethernet cable directly to my laptop or PC. If i connect the same ethernet cable to the router, all the 3 led lights(Power, Internet n wifi signals)for the internet does light up & i am unable to connect to internet,

Can you please suggest a solution to my problem?

Details:

Model Number: JNR1010v2

ISP: Excell Media  (Provides an ethernet cable to home).

Service provider provides staic IP,subnetmask,default gateway etc

Thanks in advance
