MR1100-100 LTE router : can I configure it to act only as WiFI repeater ?

Hello, have the Nighthawk MR1100-100 in my mobilehome / motorcaravan and works technically fine.

 

here my issue and question :

 

to save LTE datavolume I am using Dataoffloading as much as I can in campsite or open Wifis ( as recommended in the manual )

 

but when the wifi disappears ( pretty often on campsites ), the connection switches back to LTE, consumes my datavolume and I don‘t know about it. ( netgear telephone support told me that I can see this on the screen. true, but seriously: who checks the connection on the display every time, especially in a car or boat )

 

so what I looking for is a setting to let the router only work a wifi router, no fallback to LTE ( configurable with a setting in the app )

 

Having such a configuration and if the wifi is gone, I will see it on the tablet ( internet does not work ) and can decide what to do. But at the moment I can't easily see that the wifi of the campsite is gone and will happily download all the app updates from my mobile data volume.

 

is this possible, a good idea or am I the only one with that problem ?

 

at the moment I have bought a second ( very old and slow ) only wifi repeater to overcome that problem. When I am on a campsite I switch the Nighthawk off and use the other one. Not great to have a great product like the netgear and being forced to have such a poor workaround 

 

many thx so far and best regards from Germany
