Edimax router - MSN audio problem

Has anyone successfully managed to get an Edimax 6104K router to work
with MSN audio connections? Webcam works fine but I can't get the
audio to connect. I know the set up is OK on my PC because when I
replace the router with a Belkin, it works fine but the Belkin keeps
locking up, hence the replacement!!

The Edimax has UPnp enabled but it just won't play!!

TIA


BTW These router are also called 'GetNet' depending on where you are!

cheers,
Len
