I have since moved the DAP-1513 to the correct network and to the entertainment area. The TV and Blu-Ray are getting an IP from the DHCP. However, the 1513 seems to "disappear" from the network. However, the attached devices remain.
I have tried both the 5.0Ghz and the 2.4Ghz networks. The DAP-1513 will "disappear" until the unit is "power cycled,' no matter which radio is used.
