It is my house. I just tried resetting the routers... that didn't work, but my cell phone was able to access defender while my wifi was down. The cell phone uses a different network (ISP) to get to the web. But nothing on my house network will get Defender marine.
In fact when the wifi is back on line, my cell phone can't get it. (it seeks to use wifi over the cell network, when wifi is available)
So something is either wrong with my ISP or with my home net. (maybe my gateway).
Sorry Defender. Guess I have to go to the boat to get to you.
