Ive recently replaced my cable boxes with Windows media center and several xboxes… and many are connected via Live Wire.
My issue is when using the live wire devices, the SSDP dicovery fails… and as near as i can tell with netmon, the packets are not traversing the network. they are being dropped… everything else works… file copies…internet access , etc
If i bypass livewire and plug them all into a regular router… everything works fine.
I found some post on an issue with SSDP packet drops with INTELLON
I cant find if WD livewire uses intellon , but there definitely seems to be a problem with this device and packet dropping but bassed on this ; it does : http://www.anandtech.com/show/3860/powerline-networking-with-the-western-digital-livewire
