I was able to reset the gateway, put it into AP mode, connect to it’s network using the WiFi password, and then when I try to connect to http://192.168.4.1/ after a minute or two I just get “Connection timed out”
Is this unit a dud, and I should return it for another one?
I got connection timed out in both the browsers on my Android phone, Chrome and Brave.
I got out my laptop and managed to get connected to the web page that way and setup the router, but it was completely non-obvious that this would work.
I believe the gateway was also having problems with the Band Steering on my wireless router, but I’m not sure about that.
yes that’s the way to do it 
everything working now ?
Seems to be working well now, now I just need to get some more gateways.
