Hi,

I'm having serious synch problems with SqueezeCenter 7.0.  My setup:

- 3 x SB3 all connected wirelessly
- Linksys WRT54GS wireless router
- Xubuntu 7.10 on Via EN1200G 1GB ram

Synchronisation seems to be spot on when the server has been booted /
re-booted.  However, if it is up for an extended period of time and
usually when attempting to synch the following day, the players will
not successfully synch and there are delays of up to 6s for one of
them. 

I haven't done a great deal of structured testing but have tried a
number of permutations: synching via the remote and through the web
interface, unsynching and re-synching players, powering on in a
different order... each with equally poor results.

I have grabbed some information from the server.log (below) after
setting Multi-Player Synchronization Logging to info.  All 3 players
are configured in a single group, Player 1 initially playing, Player 2
and then Player 3 powered on sequentially.

I haven't really had synch problems with previous versions of
SlimServer, which I ran on an  XP machine.  I have also tried SC7.0 on
that machine but experienced the same problems.

First post and all that so apologies for it being a problem!  But your
help will be appreciated.


Thanks
