Firstly the Model is M7000 but this is not available to choose so I selected M7200.

I use the MiFi in a vehicle with 4 mini cameras connected to it; this sends alerts and allows me to view the cameras live, change settings on them etc.
I can do all of this from my mobile phone when not within WiFi range of the car, perfect.
I guess because that works I thought I could change settings on the MiFi unit, but in the app it states not connected, presumably as and I'm outside of it's WiFi range so can't. I get a similar response if I go to http://tplinkwifi.net
I had a lengthy online chat yesterday with a TP-Link agent, who tells me that I can do what I am attempting but I don't think I can? AM I missing something?
