Squeezebox "Cannot connect to Server", since new wireless router

Hi - I got a new wireless router, and since then I am unable to connect my Squeezebox player to Logitech Media Server.
I can connect to my wireless network successfully. I can listen to internet radio and can connect to MySqueezebox.com.
I have tried resetting my Squeezebox to the factory defaults, resetting the wireless router, restarting my computer.

Here's what happens on the steps to reset to factory defaults:

I connect to wireless network ok
I obtain IP automatically (192.168.1.100)
I select a music source ("My Music" (192.168.1.104))
Setup is Complete!
Go right to use your Squeezebox -->
Connecting to server....

then, ultimately, "can't connect to server, left to go back, right to try again...."

When I open the web control on my PC, there is no player found.

Is there something I am missing?

Many thanks! I miss my music!
