WD My World, Twonky and I Phone problem

[cavinghippy]

I have MediaLink Player Lite on my I phone and cannot get this to see the Twonky server on the NAS drive.

But, when I turn my laptop on and connect to the wireless network I then see the Music share folder (named as my laptop) and can stream the music fine.

Any thoughts why I can stream from the server with the laptop on but not see the server directly in the server list on ML lite ?

Any help gratefully accepted,

Andy
