I just bought open-box NT-505 at eBay (from Teac USA) and am having the exact same issue. The display remains NET with 'starting' flashing.
Also tried everything I can think of, power cycle, cable swap, router/hub power cycle, firmware update (v1.22), factory reset, network module reset (which I found was mentioned in JP user web site) but nothing worked.
Now I have started a message conversation with Teac USA and am waiting for their response.
It's really a very basic feature for 'network' player and I'm disappointed that they have not tested it before shipping it out.
Its USB interface on the other hand is working fine and I can still enjoy the music it plays (pretty good).
