Unable to obtain IP address, Wired connection works fine

I haven’t had any serious problems with my WDTV Live Plus from November up until I moved this August.  I bought a new router (D-Link DIR-615) and now I cannot connect wirelessly no matter what I try.  Wired connection with automatic setup works flawlessly though.  I’ve tried doing the auto setup for wireless, and manual and nothing works.  Any help?

Nevermind, I think I may have solved the problem…  If anyone is having a similar issue, just use the wired connection to perform a firmware update (it took 2 times to update completely).  After I updated the firmware the auto setup worked without a problem. 

SO UPDATE YOUR FIRMWARE TO THE LATEST VERSION IF YOU ARE HAVING THIS PROBLEM!!!

Thanks - you really helped me out after trying to find out how to update the firmware. A wired update was the solution.
