One more thing. There  is a company (Unbiquiti if I recall  correctly) I bought there Nano Station Loco M2. as I recall (two models M and M2 I got the smaller)
THe original wi-fi Ranger I understand used this module. I suggest the larger for better performance.  ONLY issue I have is the Security at some campgrounds if is the older one.. IT will not connect. Only  connects to the new one
About 5 Times the signal strength  
I put it on a flagpole
Now of course I just use my own cellular data to the Nano Station is in the basement... Conncted to my Spring Mi-Fi From FMCA
