Wireless Streaming of video (DLNA + Media Servers like Twonky)

[copadosion]

All,

I'm having issues streaming over my wireless network.  I have a need to stream some video over my wireless network from my QNAP Storage array running Twonky to a PS3.  The setup is this (all on the same subnet)

QNAP NAS --rj45-- switch --rj45-- WLC -- wireless AP -- PS3 (all on 172.16.10.x/24)

To ensure that this is neither a QNAP or PS3 issue, I have created the following topology which works fine:

QNAP NAS --rj45-- switch --rj45-- PS3 (all on 172.16.10.x/24)

I have tried some other things over the wireless (like streaming video from my QNAP to my MAC which works fine as I attach directly to the QNAP using the media server application) it appears that broadcast isn't working as Twonky is relying on some type of DLNA/uPNP function.  BTW -- I tried other applications like iTunes firefly server -- it also only works over a wired connection.

My wireless setup is straightforward in that I have the SSID broadcast (everything is on the same subnet) no advanced options like spoofing or snooping, no IPS, etc.  I'm just using a PSK.

Also -- the PS3 can connect to the QNAP server when I use a www browser so I know IP connectivity is there for wireless.

Any ideas of what I can do to enable this to work?

I have a Cisco 2500 running 7.0.116.0 and AIR-LAP1141N access points.

Thanks!

This was fixed by implementing two changes (thanks to another poster for answering a question about broadcasts!).

I enabled Multicast globally under Controller -> Multicast

And then under the Controller -> General enabled "Broadcast Forwarding"

Copa, thats correct. DLNA uses multicast to discover the devices. If you find that DLNA is not working network wide than you may need to make sure you have wired side multicast enabled as well.
