MIPAL

i have a level 1 "N" router that shows good speeds & strength. Problem is, when i am streaming music to my DNLA aware DENON 3808 AV receiver (internet radio stations), they play for only a short while then stop playing & do not start up again, so it's not a network issue with the streaming station. Also, the win7 media player is (supposed) to stream to the DENON (music from my library), but the DENON reports folders empty. My second computer links to the first computer and it's music database just fine. (folders are NOT empty). Inserting my range booster (Hawking N-speed) only confounds the problem at this point, so for testing i have connected only to the Level ONE router to the Denon wireless switch/AP (linksys). any help out there?
