Just wanted to give a note to others who might swing by this forum for help. Thanks to ivaniceman, the following worked for me:
"I turned off IGMP Proxy - didn't work
I checked the Wireless Settings -> Advanced Security Settings -> Other Advanced Wireless Options -> Switch Network to Broadband - (Mine was not already set to Broadband)"
Boom, it worked. It seems toggling between Network to Broadband triggers something.
Good luck all.
