Let me see if I understand your setup... You have your Broadband modem hooked up to your linksys switch (is this a combo switch/router or just a switch?) then from your switch you have your pc hooked up and one side of your XE 102. The the XE 102 connects via wireless to the other XE 102 which is plugged into your Music Manager?

There are a few things with this setup that could be wrong.

1. Can you ping either side of the XE 102 setup? Are the Escients setup with DHCP or static addresses? I've delt with similar systems before. Using a ping will tell you at what point the connectivity is failing.

2. At one point you COULD connect to the Escient and now you cannot. Did you move the side the Escient is plugged in to a different outlet?

3. What model is the Linksys switch?
