Hi !
I'm stucked to this problem for 4 days now, and really need your help.
I got a primary AccessPoint router with a WIFI called A and a secondary Router that is configured as Repeater bridge, relaying the A WIFI, towards a secondary WIFI called B.
All of this address a network with @ 192.168.0.x.
Airport Express AE1 is connected to WIFI A and Airport Express AE2 is connected to WIFI B.
My MacMini is wired to the Primary Access Point.
When running ITunes on it, its seeing connect to AE1 and stream the music flow, great pleasure !
But I never succeeded in reaching the AE2, from ITunes, despite that I can ping it over the network..
So I did change the config, and now have the same SSID for the WIFI A and B.
Still no progress !!
Last night tests lead me towards this : the only difference between my two airports is that they have 2 different TTL when pinging. The one working has 64 and the one failing got 255...
But I couldn't find any information on iTunes checking network packets TTL before enabling streaming..
Do you know where we could find a iTunes Guru somewhere

?
Many thankc for your help.
