It almost sounds like you have your max or min transmission unit set to
something odd and it can't stream the audio.

Subject: [slim] wireless connection very intermittent


Thanks for your reply and ideas.

I am unaware of any software I have running on the server that is hosting
the Slim Server software. I am running an apache web server and a mail
server, but no firewall software. My router (SMC Barricade) serves as the
firewall. I have specified under the wireless router's "virtual server"
settings to allow both the computer running the slim server software and the

squeezebox itself to receive messages over the ports designated in the
instruction manual.

Again, I think it is key that I have been able to perform every function on
the squeezebox EXCEPT playing music. When I hit play, it always reports
losing contact with the slim server.

I downloaded the nightly build as you suggested. When I rebooted the
squeezebox, it asked my to update the firmware, which I did (connected
directly by ethernet). However, there was no improvement in wireless
functionality. When I set up networking anew in the squeezebox and arrived
at the stage where it looks for Slim Server software, I received the
following error:

Can't allocate netpages for DLL: 4

What's next?
