Windows 7: Homegroup wont detect wireless bridge or Blu-Ray Player

Hello,

My wife and I recently started using Windows 7 (home premium 64) and bought an internet-streaming Blu-ray player, Sony model BDP S280. The USB wifi adaper for this model is proprietary and overpriced, so I instead set up a Wireless Bridge/Access point. (Amazon.com: ZyXEL WAP3205 Wireless N access point, Ethernet client, and universal repeater: Electronics)

No problems there, the device is connected to the internet through my wireless Network. Earlier tonight we were watching Netflix and Vudu movies perfectly. (I did not find any way to enter the actual SSID to the player, but I did enter the network name and WEP password to the Bridge, and the player just worked. I dug around in the player's menu to check the network connections and all the IPs match, though the network name doesn't display.)

Adding these devices to Homegroup is another story. Homegroup wont detect either the Bridge device or the player. Now, I checked Sony's support site and it definitely lists this model under DLNA-supported devices:


I also couldn't connect to the Player using it's IP address through my browser.

I'm no wiz at networking by any means, but I don't understand why I can't detect a device that I know for 100% certain is on the network. Both devices are powered on, of course.

Any help, thoughts, or Ideas would be greatly appreciated. Thanks in advance.
