Is your router "B" or at least "G"? "B" may be too slow. Have you checked signal strength at the SB's location with a laptop or similar device?
When you change to a wired connection, have you changed the settings? You will still be connecting wirelessly if you don't reconfigure the settings.
Did you call Logitech's help line?
