M6 PRO Wifi Signal Dropping Out

May I  remind you, in your initial post in this thread, you also mentioned that, You have a"Nighthawk M6 Pro" mobile device, In that you've been using it for sometime "A fewYears". I'm fully aware it has Wifi capability, & it has also a "Builtin Ethernet port" socket too!

A separate network Ethernet port switches, are not too expensive, and come in various form factor sizes, as in "Small portable one", or "rack mountable" expensive ones too. 

Like I had mentioned before above, there are some limitations, to how one uses their own mobile router devices!

Thanks, but there is no cable NBN line or Ethernet option at the property, hence why we are using a wireless mobile modem for wifi signal.

That doesn't matter!

There is a (Single Ethernet port socket) on your mobile router device already. All you'll have to do is ask someone with some technical experience to provide you with an ethernet cable.

 You can get them in various lengths sizes, via online, or from an electronic shop on the high street near you.

• Pro's & Con's - It's dirt cheap Wi-Fi cctv cameras has no wiring connection. However, it has to be (working) within Wifi range of your router device, and free from interference e.g building insulation, or metal beams, or other electrical devices etc. One more thing to add, in your neighbourhood there might be other users on the same 2.4Ghz frequency as you. But on their own wifi setup, which might affect wifi performances to some degree, in your area.
