1. The router/ modem was offline and it needed a reboot which I was not able to do because I am away. I confirmed this by not being able to access data from two ports of the router. (Solar panel status and my DVR of the camera security system.) 2. Well before this event, the DVR is the one that usually crashes. I spoke to TPG on the phone was told verbally that DVR constant uploads (to cloud server) have exceeded my bandwidth connection. As a compromise I normally put the DVR offline by disconnecting the data cable b/t DVR and router when I am at home. I only make the DVR online when I am away from home. This time they must have got desperate and crashed my router because I am away for too long. ... View more

This confirmed for me that any external request for connection (with proper login credentials) can see my NVR port.  Tried with phone on mobile data (WiFi OFF) with the App and obtain a successful online connection. I can a peaceful sleep tonight. ... View more
