Howdy,
My NEO Gateway has the no signal and no ethernet lights on. We contacted Tesla because our last one had the no signal light on as well and they sent a new NEO gateway and the new one was connected and There is a link light on the port on the back of the modem. There was never any instruction that you have to do something to connect it to the solar panels. Just plug it in to your modem do a power cycle on the panels and other equipment but nothing about logging into it in any way. Most other wireless equipment you have to enter a password to show that you have permission to be on that device if not anyone can login into my solar equipment I would think.
