I just received one of these as well and have had no network issues whatsoever - it grabbed on right away.
Factory reset probably your best bet then before you do anything with your system move the unit over to a PC and update the software on the unit to 1.22 via the Teac Japan site. You need a USB to micro USB cable to do this and the NT-505 needs to be directly connected to the computer.
Plug in Ethernet cable, open the Lumin app and you should be in business.
Inital impressions are very good - separation and tone of individual instruments and voices are outstanding, seems to handle MQA files quite well. Took awhile to get the settings where I wanted them but having the ability to tailor the sound a bit seems to be worthwhile if you have the patience for it.
Hopefully you can get it going in a matter of minutes not hours I'd try rebooting your network as well if resetting and updating doesn't work.
