Gateway Ping Failure - stumped

[awsure]

So, I just picked up a Netgear N300 because my D-Link pooped out on me and I cannot get my Dish Network TV service nor my Samsung Blu-Ray player on the network. I am using a powerline adapter for connectivity on both of the aforementioned items and they were working just fine with that setup before the D-Link failed.

Now I am running the connection test on my Blu-Ray player and it's telling me that a gateway ping failure exists. I don't really know how to proceed. All my other wired and wireless devices (laptop, phones, iTouch's, Wii, desktop) are up and running fine so I suspect the Netgear is playing nice with the powerline adapters for some reason.

I've tried powering everything down and back up again and that's not changing the situation. Please help.
