I have been having problems with mine as well and have tried a number of things including a new router, firmware updates, factory resets, different cables, etc. The problem seems to be a result of using a wireless client to establish the connection. I ran an ethernet cable to it a couple of days ago and it has been stable since then. I've connected my Roku, TV, home theater pre-processor, and Oppo to the wireless client and they all worked, so I'm stymied by why it won't work with the TEAC, but that seems to be the issue in my case at least.
Before doing that I had put in a support ticket with TEAC. When they replied, I asked why it wouldn't work with a wireless client and will post an update once I hear back from them.
